The HE 5684 Ethernet Controller extends the "Imod Eco"Product range from Hesch. The IEC 61131-3 freely programmable, multitasking controller with an up to 450 MHz clocked ARM9 CPU can directly drive up to 16 I / O modules of the series and supports the multi-vendor development environment "Codesys V3". As a result, the product can take over both autonomous control functions as well as relieve the higher-level control technology by outsourced functions or supplement it with additional functions.

The fieldbus controller with integrated 2-Port Ethernet switch transmits data with 10 or 100 Mbit / s and provides an internal 512 kB of large program memory as well as 256 kB data memory. As transmission protocols, both Modbus / TCP and EtherNet / IP are supported. During parameter setting, the Ethernet controller can be configured optionally via the fieldbus or the front-side interface.

The interfaces of the HE 5684 are complemented by two USB 2.0 host interfaces as well as a slot for a microSD (HC) card, which can be used as memory extension, program memory or recipe memory. This makes it easy to replace the controller without reprogramming and configuration, or make a quick process change by changing the memory card. For web-based applications, a web server is integrated into the controller to store HTML code. The 71,6 mm wide controller is mounted by snapping onto an 35 mm mounting rail.

Imod Eco was designed as a decentralized and modular I / O system for building automation. Eco stands for both the form factor of the housing for the installation technology, as well as for the fact that the functionality is tailored specifically to the requirements of modern building automation. A wide range of input / output modules opens up numerous control functions that support the various modern serial communication standards and wireless technologies.
