Absolute reflective encoder chip for new encoder technology

12.03.2020/XNUMX/XNUMX | IC house presents new absolute Reflexive encoder chips, which now enable accuracies in optical sensors for position and speed that were previously only achieved by transmitted light encoders. Designing a universal sensor platform for the widest possible range of applications is a revolutionary approach in encoder technology. This approach is on the verge of opening up a variety of new applications Robotic and Automation to develop.

There are already first applications of the new encoder chip platform as a groundbreaking further development of the Encoderblue technology from IC house.

Wherever a compact design and high mechanical tolerances are required along with high absolute position resolutions of 22 bits or more, the IC-PZ can be used as a highly integrated System-on-Chip are used in rotary and linear measuring systems. In the future, this will lead, among other things, to further miniaturization of motor feedback systems. The technology is particularly suitable for implementation in robot drives. Lidar sensors in autonomous driving applications are also possible applications for highly accurate reflexive position sensors.

Use in the robot arm

The chip has two scanning sensors that scan the absolute track with pseudo-random code and the incremental track on the reflective code disc. Thanks to the Flexcount and Flexcode functions, the resolution and disk diameter can be largely freely selected. This is of interest, for example, for applications in which several drives with different code disk diameters are used, such as on the joints of a robot arm or in highly dynamic multi-axis systems.

Robot In the future, manufacturers will be able to use the IC-PZ as a universal sensor platform and simply select and parameterize the different diameters from the robot foot to the robot gripper. In addition, the position values ​​of all axes of a robot arm can be synchronized particularly easily using the bite protocol.

Electro casting resins reliably cool electrical and electronic components

For encoders with a code disk diameter of 26 mm, the IC-PZ can B. over 4 million angle values ​​per revolution can be resolved (22 bits). Code disks with a diameter of 9 mm up to linear position measuring systems with a maximum of 6,71 m measuring distance are supported. The blue LED is integrated in the 5 x 5 mm2 chip. automobilecalibration and analog on-chip signal conditioning for offset, amplitude and phase shift simplify installation and ensure consistently high signal quality during operation.

Measurement method with lensless design

The reflective measuring method with a lensless design requires a significantly lower installation height compared to transmitted light encoders. Much larger mechanical tolerances are possible when adjusting the sensor chip relative to the code disk (X (tangential): ± 0,5 mm, Y (radial): ± 0,4 mm, Φ (rotation): max. ± 2 ° , Z (air gap): 1 to 2 mm). Even the so-called egg or the eccentricity error of a code disk is compensated dynamically on-chip.

Air circuit breaker, digital protection relay and soft starter

The available interfaces of the IC-PZ are very flexible. Three of the five output interfaces can be chosen freely and in parallel: Quadrature signals ABZ, analog Sin / Cos for processing with an external interpolation module, UVW, SPI and Biss / SSI.

Secondary encoder for significantly more accurate robots

21.11.2019/XNUMX/XNUMX | With a Secondary encoder the absolute position accuracy at the tool center point of a robot arm can be increased by up to 80%. This means that industrial robots can also perform more precise tasks in assembly technology, e.g. B. the Automotive industry take over. Heidenhain In addition to the motor feedback, builds a secondary encoder on each robot axis after the Transmission

There he records the actual position of each Robotic joint without transmission error. A comparison of the position data from the motor feedback and the secondary encoder on each axis of the robot arm also allows the retroactive forces from the machining to be determined.

A typical meter solution for highly accurate Robot consists of the inductive Heidenhain rotary encoders of the type EBI 1100 or EQI 1100 as motor feedback and an inductive AMO angle encoder WMKA / WMRA as a secondary encoder. Thanks to its high level of insensitivity to dirt, the protractor can easily be attached to the outside of the robot.

For precise positioning of the robot on a longitudinal axis along large workpieces, the LIC 2100 is an open, absolute length measuring device to disposal. It enables high travel speeds of up to 600 m / min, so that the robot can quickly cover long travel distances of up to 28 m.

Encoder-based strain gauge digitizes building monitoring

May 15.05.2029, XNUMX | Bridges, wind turbines, cranes and similar large structures are exposed to particularly high loads. Therefore, their safe operation requires extensive monitoring. For this purpose, Heidenhain and Leine+Linde are presenting a new series of measuring devices: The ESR strain gauges deliver a highly accurate, digital measurement signal and are particularly easy to install.

The ESR strain gauges open up new possibilities for short-term, recurring or permanent strain and load measurements. They are the highly accurate, robust and reusable alternative to traditional systems for this Monitoring of large structures. What is completely new is the use of an electro-optical rotary encoder for measuring strains and outputting digital measurement signals.

The ESR strain gauges use the robust and proven Rotary encoder technology for measuring the change in length between two points. These two points are fixed 200 mm apart on the object to be measured. One measuring point is in line with the axis of the encoder shaft, the other at the end of a connecting rod. Every relative change in length of the loaded measurement object compared to the parallel, unloaded connecting rod leads to an angle change on the rotary encoder, which is used to detect expansion or compression movements.

Based on the selected geometries, an increment of the encoder corresponds to a change in length of 5 nm or an elongation of 0,025 µε. According to the measuring range of ±5000 µε, this results in an available resolution of ±200 values or over 18 bits. This is approximately five times more measurement information than in conventional installations with film-based strain sensors.

The ESR strain gauges work without fatigue and, thanks to their high sampling frequency, are also suitable for measuring in dynamic applications. With protection class IP66 and an operating temperature of -40 ° to +100 ° C The encoder is well protected from environmental influences and is optimally designed for outdoor applications.

Because the material of the connecting rod can be selected according to the material of the test object, the ESR strain gauges offer constructive, passive temperature compensation. Because due to the identical coefficients of thermal expansion of the connecting rod and the object to be measured, temperature-induced strains are not measured.

Absolute encoder with interface for numerous variants


19.02.2019/XNUMX/XNUMX | For position measurement in machines and systems with Siemens Controllers offers Heidenhain Absolute encoder with Drive-Cliq interface from Siemens. They deliver position and operating data safely and directly to the controls.

Thanks to the non-contact, magnetic Multihall technology, measured values ​​can be recorded reliably even if the machine housing is e.g. B. is filled with oil or water due to a leak. The sensor housing has integrated protection against magnetic fields. The sensors function in environments with field strengths of up to 0,5 T. They are available with redundant electronics for safety applications. They also work with high vibration loads, strong shocks and temperatures from -40° to +85 °C.

Posihall sensors are suitable for use in packaging machines, Food Processings machines, in the robust stainless steel version especially for mobile work machines or for applications in the offshore area as well as for solar and wind power plants.

Inductive and optical rotary encoders with high control quality


09.11.2015/XNUMX/XNUMX | The rotary encoder program from Heidenhain has the right solution in its portfolio for every task and requirement: whether small, large, single or multi-turn, with or without integral bearings, and optical or inductive. With both inductive and optical scanning, the rotary encoders offer high control quality and system accuracy for the respective applications. 

There are variants with functional safety and mechanical fault exclusion, which prevents the shaft and stator connection from coming loose.

Modern inductive rotary encoders do not need to hide behind their counterparts with optical scanning. The devices with optical scanning are still the first choice for the high end of the application spectrum. In terms of control quality and dynamics, however, the new inductive solutions have made up ground, and in terms of robustness they are even superior. This is shown by comparative tests between the new generation of inductive rotary encoders, their predecessor models and optical encoders.

Tension belt encoder for angle and speed measurement 

It is also essential for the practical suitability of these encoders that the inductive variants are in many cases compatible with the optically scanned rotary encoders. Due to the mechanical and electrical compatibility achieved in this way, the suitable rotary encoder for the respective control requirements of the application can always be selected from the manufacturer's portfolio and the Number of engine mechanics minimized will. With the current inductively scanned series, the permissible mechanical mounting tolerances have also been greatly expanded, for example by a factor of 2 for the permissible axial movement.

For a simple assessment of the mechanical attachment, the rotary encoders generate an evaluation number that the servo converter can be read out via the purely serial Endat interface. In addition, the rotary encoders also support monitoring of the temperature in the rotary encoder and motor. An integrated temperature sensor monitors the encoder temperature. In addition, an external temperature sensor in the motor winding can be connected to the rotary encoder. The rotary encoder evaluates both data, and the downstream electronics can read them out digitally via the Endat 2.2 interface without interrupting the control cycle.

Rotary encoder, counter and monitor in one device - specialist lecture



09.02.2015 | Magnetic principles of action in combination with unique signal evaluation, supported by high-performance microcontrollers: This is what makes the new encoders of the IFM Electronic a real alternative to traditional optical encoders. Thanks to extended, intelligent functions, these can be used flexibly for different applications in the field of motion control. Display, control buttons and convenient parameterization as well as diagnostics via IO-Link make them unique.

First, they are as Incremental usable. The resolution between 2 and 10.000 pulses per revolution can be freely adjusted. The devices can also be used as counters. Among other things, counting direction (up / down) and switching points can be freely selected. The third operating mode is used for speed monitoring. The user sets a speed range which, when exceeded or undershot, switches the outputs. The encoders thus work independently as speed or standstill monitoring systems.

All functions and parameters can be set on the device using buttons and an LED display. During operation, the display shows the current depending on the mode set Pulse, counter or speed values at. Due to the two colors (red / green), the user can immediately see whether the machine is in the OK range or whether limit values ​​have been exceeded. In addition, the display can be rotated electronically by 180 degrees, which allows flexible installation positions. In addition to setting directly on the device, the rotary encoders can also be parameterized completely and conveniently via IO-Link. This communication option makes the devices ideal for Industry 4.0.

Standstill monitor detects the standstill of drives without sensors

The high shock and vibration resistance enables use in rough applications. The cable outlet or the rotatable M12 connection on the plug-in devices can be used both radially and axially. Ultimately, the selection of the right rotary encoder is reduced to the right flange and the shaft - everything else can be freely configured by the user. There is a basic version for users who want to use the device as a transmitter and do without buttons and a display. This can also be set completely via IO-Link.

Absolute rotary encoders in protection class IP66 and IP67

21.06.2013/40/60 | Johannes Hübner has further developed the XNUMX and XNUMX series of his absolute value encoders and has adapted numerous components even more intensively to applications under extreme operating and environmental conditions such as in steel and rolling mills, in mining and in crane and port systems. Compared to the previous versions, the new series have, for example, even bigger Bearing with a higher dynamic load rating, so that the absolute rotary encoders are less affected by wear and damage under continuous load.

In addition to the usual interfaces such as Profibus, Profinet, Devicenet, Ethercat and SSI, the selection of interfaces has been expanded to include the option of a parallel outputs expanded. This type of transmission is very fast because the data is transmitted simultaneously via lines running in parallel and is not sent one after the other in one data packet, as is the case with bus technology. In addition, the 41 series also offers absolute rotary encoders with safety certification SIL3 / PLe according to IEC 61508 / EN 13849. The interfaces Profibus and Profinet are currently available here, further interfaces are in preparation.

The thick walled Aluminum casing and the encapsulated interior ensure high resilience even under inhospitable environmental and environmental conditions. The 40 series is available in two designs: with a solid shaft (11 or 14 mm diameter) for encoder attachment using Clutch and with a hollow shaft (20 mm diameter) for direct encoder mounting on the drive shaft. The single-turn resolution is a maximum of 16 bits (number of steps: 65.536) and the multi-turn resolution is 12 bits (number of revolutions: 4.096). The encoder version can optionally be designed in such a way that it can withstand temperatures down to -40 °C and shock loads up to 450 g.

The models of the new series 60 are hollow shaft devices with a bore diameter of up to max. 50 mm with keyway. The absolute rotary encoders are particularly suitable for the attachment of additional devices.

Absolute rotary encoder with SIL3 certificate for heavy duty

27.11.2012 | Johannes Huebner shows two new absolute encoders with SIL certificate. The AMP(H) 41 (Profibus) and AMPN(H) 41 (Profinet) specially developed for heavy industry are certified according to DIN EN 61508 up to safety integrity level SIL 3 and according to EN ISO 13849-1 up to performance level PL "e".

From spring 2013, the sensors will be available in two designs: AMP 41 or AMPN 41 with a solid shaft (14 mm diameter) for encoder attachment using a coupling, and AMPH 41 or AMPNH 41 with a continuous hollow shaft (20 mm diameter) for direct encoder attachment on the Drive shaft. Both the devices with a Profibus and with a Profinet interface are used for data transmission Profisafe protocol used. The total capacity is 28 bits, of which 13 bits single-turn resolution (8.192 steps) and 15 bits multi-turn resolution (32.768 revolutions). An additional incremental output offers 4096 pulses.

The new encoder is particularly suitable for areas of application in the heavy industry such as in steel and rolling mills, in mining, in crane and harbor systems and generally in applications with extreme operating and environmental conditions.

Properties such as a thick-walled aluminum housing, large ball bearings with a high dynamic load rating and an encapsulated interior, even when the terminal box is open, predestine the encoder for  heavy industry applications. All devices are also secured with screw against vibrations and fitted with feather keys for form-fitting shaft connections. With hollow shaft mounting, the long-armed, robust torque arm ensures higher signal quality. Due to the available degrees of protection up to IP 66/67 and the materials used, the absolute rotary encoders are also suitable for use in salty environments.

New encoder technology with dreams of the future

02.02.2011 | Robert R Wachendorff, Managing Director Wachendorff Automation GmbH & Co. KG, Geisenheim, presents the new Technology EnDra and claims that these rotary encoders will unleash creative destruction.



Incremental encoder with magnetic ring

12.07.2010 | ASM presents the magnetic incremental encoder PMIR7 in connection with the sensor head PMIS4 from the "Posirot" product family. The magnetic rings are available for three different shaft diameters, achieve up to 184.320 pulses per revolution and are suitable for difficult environmental conditions. The incremental, non-contact PMIS4/PMIR7 measuring system consists of a PMIS4 sensor head and a PMIR7 magnetic ring with an index mark.

The Sensor head is made of a metal housing that is closed on all sides and can be combined with three different magnet rings with an inner diameter of 27, 35 or 50 mm. The position sensors are an accurate, fast-working and robust measuring system with which a resolution of up to 184.320 pulses/revolution can be achieved. The guide tolerance is ±1 mm.

The shielded metal housing of the sensor head offers a high level of protection against electromagnetic interference and thermal overload and has protection class IP67. Since the measuring system works magnetically, it is insensitive to contamination, e.g. B. by oil or dust, and therefore suitable for use in harsh, dusty industrial environments magnetic rings are available with decade, binary or degree division and achieve up to 102.400 pulses/revolution, 131.072 pulses/revolution or 184.320 pulses/revolution. The temperature range extends from -40° to +85 °C, the maximum pulse frequency is 480 kHz. HTT, TTL and TTL24V are available as output types.

Atex rotary encoder with fieldbus interface 

01.06.2010/XNUMX/XNUMX | Fieldbus technologies are also increasingly in demand in potentially explosive areas. However, this trend is being slowed down by a very limited range of corresponding sensors with integrated fieldbus interfaces. To counteract this, Kübler now his Sendix fieldbus encodertechnology in a corresponding flameproof enclosure. The single-turn and multi-turn encoders are therefore approved for zones 1, 2, 21 and 22 and have the latest fieldbus profiles from Profibus and CANopen.

The shock and vibration-proof encoders work flexibly with the high resolution of up to 29 bits. With a protection class of IP67, the temperature range from -40 ° to +60 ° C, the housing and flange seawater-proof aluminum they are ideally suited for outdoor use in offshore or coastal applications. The compact design with an installation depth of only 145 mm, a diameter of 70 mm and a space-saving cable outlet rounds off the diverse and flexible options for use in hazardous areas.

Magnetic encoders as an alternative to conductive plastic potentiometers

15.04.2010/XNUMX/XNUMX | Thanks to their modular design with a separate sensor head and capsule, the magnetic encoders in the Eco Turn series can be Megatron combine to form numerous designs. Technical details make the used as a programmable sensor or adjuster a high-quality alternative to conductive plastic potentiometers. Its robustness and flexibility also compare favorably to optical encoders.

The EcoTurn can realize adjustable rotation angles between 0 and 360°. Any desired angle is programmable as full scale. The non-contact magnetic measuring method with Hall sensors is not only less susceptible to wear and tear than potentiometer solutions with conductive plastic, it is also vibration-resistant and can therefore also be used in environments that overwhelm other sensor technologies. The sensor capsule is filled with a casting compound so that vibrations and other environmental influences have no effect.

The electronics are optimally protected and at the same time this part of the sensor is waterproof. For the mechanical connection to the machine, there is the option of mounting via bushing or flange and a version that does not require any shaft or bearing at all. Here a magnet is attached to the machine shaft to be measured using a magnet holder. This means that standard shaft diameters from 4 to 12 mm can be covered.

3D printing service – online and fast

The Eco Turn is also ideally suited to safety-related tasks. The series includes fully redundant versions in which supply voltage, ground and output signal are completely separated. If she signal curves The customer decides whether they should run in the same way or in the opposite direction. A switching output is available for sizes 28 mm and larger.

Ethernet APL

First solution for modernization and migration


12.02.2019/XNUMX/XNUMX | For the first time, Ethernet-APL offers a solution for migration and modernization. The well-known type A cable can still be used. The Pepperl+Fuchs Field switch communicates either the Profibus PA or Profinet fieldbus protocols.

The field device recognizes the electrical signals and protocols sent by the connected subscriber and automatically converts them into data for the control system. Early adopters benefit from this as soon as not all devices are equipped with an APL connection in the initial phase of this technology. The same applies to the Modernization of plantswhere the investment in the instrumentation needs to be protected. The technicians then only swap or replace devices as needed.

End users also want it to be broadcast safety-related signals via ethernet. Ethernet APL proves to be an enabler here. The protocols offer functions in communication that could soon be found in field devices with APL technology. In this way, the same infrastructure can be set up for process signals and safety signals.

Standard for location technology with UWB, RFID, 5G, GPS

The transmission between the safety controller and field devices takes place after SIL 3. The infrastructure does not have to be considered separately here. The concept of the "black channel" was conceived for this. It defines the encapsulation for the data and transmits it in a normal telegram. This considerably simplifies the work of manufacturers, planners and operators.

Ethernet APL offers great benefits for process technology. It defines all properties for reliable operation. Pepperl + Fuchs brings decades of experience with patents, know-how and participation in working groups to the collaborative development. Ethernet APL will be a robust and modern Ethernet in the field of process plants in 2021 ready for the market.

The time has come for Ethernet APL video

The following videos give an insight and review of the respective development status of the Ethernet standard APL for process automation:

The physical layer makes Ethernet acceptable for process automation

17.10.2017 | What is taken for granted in factory automation is just beginning in process automation: the use of Ethernet technologies from the office to the shop floor. Pepperl+Fuchs is working on the Development of a new physical layer.

Too high installation costs, lack of robustness and, last but not least, a lack of concepts for the explosion protection have so far spoken against establishing Ethernet-based communication in process engineering systems. With the "Advanced Physical Layer" (APL), which Pepperl+Fuchs is now developing, field devices are connected directly to Ethernet networks.

In this approach, power switches and field switches form the core components for a 2-wire Ethernet field communication. The power switch is located in the non-hazardous area and connects standard Ethernet networks to the physical layer. It supplies the field switch and connected field devices with power via two-wire lines up to 1000 m long.

This eliminates the need for an additional Power Supply. The Field switch takes over this function in the hazardous area and ensures both the signal transmission and the power supply of up to twelve intrinsically safe field devices. Here, the cables between the switch and field devices can be up to 200 m long. The power switch is located in the non-hazardous area, while the field switch is installed in the hazardous area

Industry 4.0 in the process industry




The direct one realized with Field and Power Switch Connection of field devices to the Ethernet enables consistent, transparent communication from the process control system down to the field level. Gateways are not required. In this way, field devices can communicate directly with the process control system and thus become Industry 4.0 components. At 10 Mbit/s, data transfer is almost 10.000 times faster than with Hart, which enables additional functions. These are, for example, access to the web server, which makes device documentation available, or the display of process, parameter and diagnostic data in real time.

Support power switch and field switch all common Ethernet protocols, such as Profinet, Ethernet/IP or Ethercat, but also IT protocols such as MQTT or OPC UA. With the latter, connection to cloud-based systems is also possible.

Because with the Advanced Physical Layer Standard fieldbus cable can be used, it is easy to migrate from classic fieldbus systems to Ethernet technologies: the existing one wiring can remain. The field switch supports both Ethernet 2-wire devices and conventional ones fieldbus Devices. The switch automatically recognizes which type of device is connected. In this way, existing fieldbus components can easily be supplemented with Ethernet-capable field devices. Since gateways are no longer necessary, overall investment and operating costs are reduced and Industry 4.0 applications make economic sense.

Nominated for Industry 4.0 Innovation Award 2017

For the second time, VDE Verlag is presenting the Industry 4.0 Innovation Award in cooperation with ZVEI. Pepperl+Fuchs sent along power switches and field switches an innovation for communication in process automation and made it through the first round of the competition. An independent jury chose the top 10 from all submissions. In the online voting process, everyone can now vote for their favorites until October 31.10.2017, XNUMX.

Gateways

You can find the current Gateway innovations here.

Gateways for the fast and safe way to IIoT

19.11.2018 | HMS Industrial Networks presents with "Anybus Communicator IIoT" and "Anybus X-gateway IIoT" two new gateway families that support MQTT and OPC UA and thus enable data exchange between devices in industrial networks and IIoT applications.

The new gateways enable thanks to the support of MQTT and OPC UA easy entry into the Industrial Internet of Things (IIoT) and cover all common industrial communication standards towards the production level. 

The Advantage for system integrators, machine builders and device manufacturers is that of almost all devices that use Industrial Ethernet, fieldbusse, CAN or serial protocols communicate, data can be easily and securely transmitted to IT systems and IoT software. 

It doesn't matter whether the data is generated in a single device, multiple machines or an entire automation system. Anybus Communicator IIoT and Anybus X-gateway IIoT transmit this data in modern IIoT systems, where they can be seamlessly integrated, monitored and analyzed. Data from new and existing systems can be integrated. This makes processes more transparent, which, for example, enables cross-plant decisions, higher productivity or more sustainable production.

The Anybus Communicator IIoT can provide the IT side with data from field devices that work with serial protocols or CAN. The Anybus X-gateway IIoT integrates data from fieldbus and industrial Ethernet networks. Typical applications of the gateways include, for example, the data integration of Modbus RTU and TCP, CAN-based protocols, Profibus-DP, Ethernet/IP, Profinet, Ethercat, Powerlink and CC-Link.

IO-Link gateways connect intelligent sensors in the hygiene sector

29.05.2017/XNUMX/XNUMX | Extra for the food industry IFM Electronic developed new IP 69K field modules with four or eight IO-Link ports and full V1.1 functionality. The decentralized IO-Link masters serve as a gateway between intelligent IO-Link sensors and the fieldbus. Master and device can be conveniently configured with the "LR Device" software. If desired, the integrated "LR Agent Embedded" sends the process values ​​directly to the ERP systems via the PLC.

The intuitive software LR Device finds all IO-Link masters in the network and creates an overview of the entire system. All connected sensors are shown with their respective parameters. This means that all sensors in the system can be parameterized from a central location.

Especially for use directly in wet areas of Food industry a special housing material was developed that offers the high degree of impermeability according to IP69K. The halogen and silicone-free materials and production processes are identical to those of the connecting cables in the "Ecolink EVF" product range.

This technology guarantees reliable and permanently tight sealing M12 connections. In addition to high-quality materials specially tailored to these applications, intensive monitoring during and after production ensures the highest quality standards.

Gateway closes media break between Ethernet and fieldbus


16.10.2014 | The "Nethost" gateway from is suitable for new control generations without a fieldbus connection or for controlling peripherals via PC via Ethernet Hilscher as a bridge between fieldbus and ethernet. Controlled via native TCP/IP, the device supports the full range of functions of a fieldbus PC card. It can be controlled remotely and transmits cyclic and acyclic data as well as alarm and diagnostic messages.

Real-time Ethernet systems are clearly established, but the range of services offered is not required in all cases. If simple Ethernet meets the basic communication requirements, the connection to the fieldbus can be implemented via a gateway. Nethost integrates the fieldbus with little effort and allows remote control as if the interface were local.

"The control provider using the gateway could then follow the slogan: 'Controls 1000 Profibus inputs and outputs in a millisecond without their own Profibus connection,'" explains Armin Beck, product manager for gateways at Hilscher Gesellschaft für Systemautomation mbH, the benefits of the device. "Because due to the design, the controller would only have one Ethernet interface and still be able to address Profibus I/O peripherals." Since Nethost simply 'hosts' the missing fieldbus interface as an Ethernet node, thanks to simple TCP/IP Protocol and the high transmission speed of 100 Mbit/s an adequate replacement for the previously integrated fieldbus solution.

Bring Ethernet and fieldbus in line

The savings potential in the construction of modern production plants through the use of Industrial Ethernet is high. Advantages are, for example, the continuity of the communication system, the use of a uniform cabling standard, the simple redundancy capability to avoid failures and short cycle times with high deterministic data transmission.

To the chagrin of the machine builder, however six Industrial Ethernet systems established on the market. Implementation and support of each system requires investments. "The new performance data came at a high price," Beck continues and asks: "Does it always have to be Ethernet suitable for industry?" While retaining the fieldbus, simple Ethernet is also sufficient for the office world. In fact, it can make sense to continue using the existing fieldbus potential. For example, hard real-time capability is only required in motion control applications. In over 90% of all cases it is irrelevant. The low cycle times of the Real-Time Ethernet systems of less than 1 ms are only rarely required.

So machine segments that have been set up with a fieldbus have proven their worth over the years and now they have to be linked to Ethernet as well controlled remotely are used, Nethost qualifies for this purpose due to its low latency of 1 ms and the support of simple TCP/IP. The bandwidth of the 100 Mbit Ethernet is so high that up to 5 devices can be addressed simultaneously via one strand.

Investment protection for fieldbus devices

Hilscher also observes that Ethernet trend in the sales figures of its products. Demand has increased noticeably in the last two years. However, with a market share of over 70%, fieldbus technology is still strong and will continue to exist for years to come. "The duty of the machine builder to support both systems for a long time becomes a free choice for us," explains Beck. In the concept phase of the new product, the focus was therefore on investment protection. "The aim was not to immediately replace fieldbus with Ethernet, but rather to merge both technologies in the simplest possible way."

In this way, proven fieldbus devices can continue to be used and a broader market can be addressed.” The idea of ​​a TCP/IP based gateways. "There are already a few TCP/IP gateways on the market, but these devices only convert the pure I/O data," emphasizes the gateway specialist. "Our Nethost supplements the range of services here with acyclic services, diagnostics and status messages and thus completely integrates the subordinate system."

Graphic HMI operator terminals for industrial automation

For example, working as Class 2 Profibus master, the sending of DPV1 read/write services or the pure CAN telegram transmission in addition to the actual protocol handling as a CAN open master. TCP/IP makes data transmission to and from the nethost secure. The transparently transmitted telegrams are coded and classified according to type and purpose in a few bytes at the beginning of the telegram. The coding logic is in the C source code. It maps to a socket interface and is therefore easily compatible with any TCP/IP stack.

On the application side, it abstracts to a simple procedural API function interface. Catchy functions such as Open, Close, Reset, Send, Receive or IO Exchange guarantee quick understanding and thus short integration times. The functions are decoded in the device and executed remotely. It is based on the RPC principle (Remote Procedure Call). A DLL enables immediate use of a nethost under Windows. A C toolkit shows an example implementation under Linux to make it easy for embedded programmers to get started.

Remote access via remote PC card

“The access functions for a nethost are in line with the manufacturer's platform strategy Once integrated - everything works identical to those of the PC cards,” emphasizes the product manager. Simply exchanging the PC cards for the Nethost DLL under Windows, for example, makes it possible to exchange both product series for one another without having to change the user program. What was controlled locally yesterday can be controlled remotely tomorrow via Ethernet via the control level.

“The same API makes Nethost remote PC card for the control cabinet. In systems without a slot for PC cards, the device is even a direct replacement for PCMCIA cards,” says Beck, commenting on access via Ethernet. The decisive factor is: "If a system already supports our PC cards, it now also supports the operation of a nethost." For example, IBH Softec was one of the first companies to integrate the functionally identical DLL into its Step 7-compatible Soft-PLC S7-315 / Soft-SPS S7-416 and now also supports the Profibus Nethost in addition to CIFX PC cards.

The automator was also able to hire two other existing customers directly for the Nethost integration who have been purchasing large numbers of PC fieldbus cards for controlling peripherals for years. According to their own statements, after around 15 years of use, both are working on a new control generation that, due to its compactness and greater flexibility, can only communicate via standard Ethernet interfaces. Nevertheless, one does not want to do without the support of established fieldbus technology and offer a migration path from the old to the new generation. TCP/IP stack, standard Ethernet controller and the programming experience with the PC cards ensure short integration times. As a result, today it is possible to serve both fieldbus customers and new Ethernet customers alike, despite the changeover to Ethernet.

TCP / IP conversion soon also for real-time Ethernet

The next step in Nethost development has already been initiated. In the third quarter of the year, Hilscher three new variants launch. The already existing variants for Profibus, CAN open and Devicenet are supplemented by Profinet, Ethercat and Ethernet/IP masters. This takes into account the strong demand for TCP/IP conversions in the real-time Ethernet world.

All variants are configured via a bus-wide uniform FDT/DTM based configuration tool. If the target system already has an engineering tool, the alternative and open configuration via XML files ensures transparency. XML schemas bring the configuration data into the correct format and can then be loaded into the nethost after conversion into a binary file. The device can thus be fully integrated into any target system.

With this solenoid interlock there is a plastic actuator in the actuator Metal bracket integrated, which engages in the turnstile of the guard locking and thus ensures that a protective door is safely closed.

To get out of the dissimilar materials Plastic and Metal To establish a connection with high quality and resilience, a secure bond is crucial in the joining process. In one Plastic-metal composite Without a special seal, interfaces represent a constant contact surface for the penetration of water, air or other media.

Plasma seal tight as a new approach

This offers a completely new approach for a media-resistant and particularly adhesive hybrid composite Plasma sealing process Plasma seal tight. The composition of a plasma-polymer sealing layer produced in atmospheric pressure, the formulation of the plastic compound and the process parameters were coordinated in the new industrial solution in such a way that a long-term stable, media-tight composite of the component is created.

The advantages of the new process: A higher product quality can be achieved as well as a safe, reproducible and economically efficient production process - and the whole thing environmentally friendly. Because the plasma seal tight technology dispenses with the use of cost-intensive and environmentally harmful chemicals on the metal surfaces. These are used in many cases to achieve a material bond with the aid of solvent-based adhesion promoters.

FMB Bad Salzuflen – news ticker

The AZM 300 solenoid interlock is now used in many branches of industry. One of the features of the AZM300 is the novel, patented working principle with rotating shaft and turnstile. It has the advantage that the safety door is pulled into the end position when it closes and is kept closed with almost no play. The solenoid interlock serves as a door stop, which makes the use of a separate door stop unnecessary. An RFID sensor is used for reliable identification of the actuator, which enables three different levels of coding and thus also protection against manipulation.

If the new procedure is after Termination of a test phase Proven as part of the pilot project, Schmersal plans to use the new method for both existing and new products in order to be able to produce them even more efficiently.

Safety interlock with 10 kN locking force

02.09.2019 | the Schmersal Gruppe presents an integrated safety solution that offers the user a high level of safety, higher machine availability and significant savings potential. The solenoid interlock AZM400 permitted in combination with the Safety field box a much simpler wiring. A new locking device protects several people in walk-in facilities from being locked in by mistake.

The AZM400 solenoid interlock has only been on the market for a few years and has since proven its versatility. It offers a very high locking force of 10.000 N. Due to the two-channel unlocking signal, it achieves the performance values ​​for the locking and locking function PL e or SIL 3. In combination with the new Safety Fieldbox, several AZM400s can now be connected to a Profinet / ProfiIsafe node in a safety chain. This solution is significantly cheaper than equipping each individual guard locking with a Profinet interface.

Within the Safety Fieldbox thanks to the universal device interface with 8-pin M12Plug a wide range of different safety switching devices can be connected: safety interlocks, safety switches, sensors, light curtains and control panels. Safety interlocks of different designs (electronic and electromechanical) each occupy only one device connection. The advantage for the user is a significantly simplified and therefore more cost-effective wiring of safety switching devices. In addition, complex additional installations for controlling the guard locking and reading back the diagnostic information are avoided.

To a higher one Machine availability An additional digital input on the Safety Fieldbox contributes: The diagnostic signals of all connected safety switching devices - as well as the AZM400 - are transmitted to the controller via this digital input. This means that status information on the tumblers and error messages are available for evaluation.

Accessories protect against accidental entrapment

Schmersal now offers the AZM400 with new accessories: One Locking pliers protects the operating personnel of larger, walk-in machines and systems from accidentally being locked in during maintenance and repair work. To do this, the service employees attach a lock to the locking tongs when they enter the danger area, so that the door of the protective devices cannot be closed and unintentional machine start-up is prevented. The lockout tongs are suitable for installation inside and outside the danger area. Up to six locks can be attached to the locking tongs, ie up to six people can be in the danger area at the same time.

Push pull M12 connector now standardized thanks to IEC 61076-2-010?

In the event that an operator is inadvertently locked into such a system, a Bowden cable can be used as a Escape release be used. When used outside the danger area, the Bowden cable serves as an emergency release.

It is suitable for all standard aluminum profiles with a width of 40 mm and can optionally be supplemented with an escape release on the inside. If required, the solenoid interlock can also be supplied with a rod lock, which offers more stability and is therefore particularly suitable for larger safety doors.

Define the level of security against manipulation

In the new version of the AZM201, the RFID technology the requirement that the user can choose between three types of coding and thus determine the appropriate level of protection against manipulation: In the basic version, the AZM400 accepts any suitable actuator. A second version only accepts the actuator that was taught in when it was switched on for the first time. With a third variant, this learning process can be repeated as often as required. A release lock of 10 minutes prevents the short-term change of an actuator and thus increases protection against manipulation. This allows the user to choose the most suitable coding variant and thus also determine the degree of protection against manipulation.

The built-in electronics of this electronic solenoid interlock allow extensive Diagnosis of the operating status. The operating status is displayed via the clearly visible diagnostic LEDs on the device. In addition, the operating status is communicated via a diagnostic line.

Energy-efficient radio network for the Industry 4.0 factory

In addition, the AZM201 has an optional serial diagnosis line. This safety interlock can be connected in series with up to 31 safety sensors and interlocks. The resulting Manifold the diagnostic information is sent to a serial diagnostic gateway for evaluation. Each of the connected safety sensors and tumblers loads status signals, warning or error messages into the integrated PLC. From here control commands z. B. to unlock a safety switch to the devices in the series connection. The cabling effort and downtime are reduced.

Compact safety lock for heavy safety doors

01.12.2015 | The Schmersal Group has presented an extension of its range of safety interlocks: On the characteristic properties of the AZM400 include the very high locking force, the bistable operating principle and the electromotive locking bolt. The series is therefore also suitable for very large, motor-driven protective doors, for example on CNC machining centers. The combination of Electronics and sensors enable high machine and system availability as well as interesting additional functions with a very high level of security.

The safe bolt guard locking AZM400 consists of the guard locking unit with sensors and motor-driven locking pin as well as the actuator, which contains a coded RFID tag and a locking opening with two permanent magnets, into which the locking pin moves. As soon as the locking bolt reaches a sufficient depth, the protective device is considered to be securely locked. The AZM400 achieves a locking force of 10.000 N.

Integrated RFID technology

By integrating the RFID technology in the safety sensors, the coding level high according to ISO 14119 is achieved for the individually coded versions. For both the interlocking and the guard locking function, the bolt guard locking system achieves PL e and Cat. 4 in accordance with DIN EN ISO 13849-1 and SIL 3 in accordance with IEC 61508. reached due to the two-channel unlock signal. This ensures that there is no unintentional unlocking due to the occurrence of a cross-circuit, for example. So becomes a uncontrolled access to danger areas verhindert.

The AZM400 is a bistable systemthat maintains the last interlocking state of the guard locking in the event of a power failure. Even in the event of a power failure, the protective door remains securely locked in the event of dangerous overtravel movements.

The solenoid interlock enables a Unlock against a lateral force of up to 300 N. This avoids interruptions in the production process, so that the productivity of the machines and systems increases. With the integrated safety-related sensors, the stud position can be monitored and error states can be detected. As a result, the number of error messages is reduced.

The new input wiring To control the locking function, the AZM400 can be connected to all known safety controls. These can be equipped with both P / P and P / N outputs. No different versions of the AZM400 are necessary for this.

RFID sensor and position switch for preventive maintenance

01.09.2015/XNUMX/XNUMX | The Schmersal Group is showing its new generation of safety switches, which meet machine builders' expectations in terms of flexibility, higher productivity and cost efficiency. An example of this is the Security sensor RSS 16: Instead of using a mechanical actuator, the target is identified without contact. The RFID technology forms the basis that turns the safety sensor into a communication-capable component in the sense of new Industry 4.0 concepts.

The RSS 16 enables about one high tolerance for door misalignmentby sending an electronic warning signal when the offset limits are reached before the machine is switched off. The RFID sensors thus provide information that can be used for preventive maintenance. The user can therefore take corrective action at an early stage if the door is misaligned in order to avoid production downtime.

The destination can be approached from three sides. As a result, the sensor can be easily integrated into a wide variety of mounting situations. In addition, he is magnetic stop can be used so that the designer can do without a separate stop with a detent. Due to the similar design and the same dimensions, the RSS 16 can simply replace the standard AZ 16 electromechanical safety switch without changing the surrounding construction

The new, compact position switch PS 116 with security function reliably monitors laterally displaceable or rotatable safety guards. When developing the PS 116, the focus was on increasing the net benefit for the customer. The desired functions and properties included a design that was as compact as possible and universal applicability, also in order to reduce storage costs.

The PS 116 is smaller than a position switch according to EN 50047 and can therefore also be installed in cramped installation spaces. The housing is symmetrical and the operating elements can each be positioned in 45°oSteps are implemented. Therefore, the right-and-left designer can use the same switch.

Various contact variants in snap and slow action allow a variety of switching and monitoring functions. The degrees of protection IP66 and IP67 ensure that the position switches can also be used under unfavorable environmental conditions. Pre-assembled switches in cable and plug versions shorten the installation time.
