Eaton extends the application possibilities of "Smartwire-DT" outside the control cabinet. With the IP67 input / output modules, users can now integrate sensors and actuators in the field directly into the communication system. As a result, machine builders have new options, high degrees of freedom, and improved diagnostics information for IP67 system architectures.

Both the construction of new plants and the conversion of existing machines can be realized with reduced cabling and material usage. From the project planning to the design to assembly and disassembly, the user benefits in many cases from significant system simplifications.

Conventional architectures for the connection of sensors and actuators to the machine control are often associated with challenges: In a central structure and spatially extended complex systems, the wiring is usually associated with high material costs and labor input; In a distributed setup with remote I / Os in remote cabinets or IP67 I / O modules on the machine, the granularity of the ports often does not match the number or type of peripherals present, thus investing in unnecessary hardware. Extensions are difficult in most scenarios.

99 participants connected via 600 m

eaton20215Eaton now offers a solution for this: Via the Smartwire-DT network, a maximum of 99 participants distributed over a distance of up to 600 m can be linked directly to the controller. Users can connect the sensors from the manufacturer's own portfolio to the IP67 input / output modules, ranging from mechanical position switches to highly functional inductive, optoelectronic and capacitive sensors. However, as the modules are equipped with a standardized M12 interface, there is also the option of integrating all sensors and actuators normally available on the market with M12 plugs directly into the Smartwire-DT network. For sensors with their own power supply, it is possible to check whether the sensor is connected by measuring the current consumption. Consequently, the user can simply check his installation. In addition, the module locally signals its network status visually from every installation position and whether there is possibly a diagnostic message.

Individual connection allows optimal allocation

The advantages of this architecture are evident in many applications: If a wide variety of sensors and actuators are used in digital or analog versions, the use of the Smartwire-DT I / O modules allows optimum allocation. Because every sensor or actuator is connected individually. In distributed applications such as conveyor belts, it is possible to install the required sensors over a length of 600 m. The direct assignment of the module to the sensor drastically shortens the previously necessary cabling. The machine builder can now flexibly carry the required cables and install individual sensors or actuators at the desired positions. Digital and analog inputs / outputs can be combined as required.

Later, when there is a need to connect additional sensors, the network can be quickly and easily upgraded or upgraded with new IP67 modules: simply install a new unit at the desired location. Mechanical engineers only have to invest in the peripherals that are actually required for the functionality. For optimum use, the product range includes versions for connecting one, two or four sensors.

Install by clip on the DIN rail

In order to make the installation of the IP67 module as easy as possible for the user, in addition to the screw fastening, it is also possible to attach the unit to the top-hat rail or to mounting profiles using commercially available installation clips.

When integrating Smartwire-DT into automation concepts, users generally have the choice: Either they use any PLC via gateways such as Profibus-DP, CANopen, Modbus-TCP, Ethernet tIP, Profinet, Powerlink and Ethercat or they use one of Eaton's Controllers with integrated Smartwire-DT interface such as the XV100 series HMI / PLCs. With the latter, simple and straightforward concepts can be used to realize lean solutions with fewer components in accordance with the automaker's lean solution strategy.
Picture above: With the IP67 I / O modules, machine builders can now integrate sensors and actuators from any manufacturer via M12 plug-in connections into a Smartwire-DT network.
