Development and integration of a CAN and EtherCAT based IO module

The ever-increasing complexity of more and more networked machine and plant systems brings with it growing demands for state-of-the-art automation. The focus here is on constant communication and the exchange of information. IO modules, i. e. the input and output of data records – such as temperature or fill level – between an information system and its environment, is a key component of this and must run smoothly and error-free. For increased efficiency and productivity of the systems fast, stable and high-performance signal processing must be ensured.

The IO module EC-DIO32 RM35 was designed for a leading engineering company. At the beginning there was the requirement of the OEM to provide the currently used CAN IO modules from Sontheim now also for EtherCat. Sontheim's development division resulted in the innovative proposal of the EC-DIO32 RM35 – which reduces downtime and enables higher machine availability. This is made possible by our freely configurable blocks of different inputs and outputs. A selector switch can thus be used to choose the desired specification required for the specific application. The big advantage in addition to the summary in a single module is the integrated diagnostic function. This allows service employees to clearly identify faults.
