CAN and EtherCAT based IO module

Development and integration of a CAN and EtherCAT based IO module

The ever increasing intricacy and complexity of more networked machine and plant systems brings with it rising demands on state-of-the-art automation. The focus 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 without errors. For increased efficiency and productivity, the systems must ensure fast, stable and high-performance signal processing.

Thanks to the uncomplicated integration of both CAN and EtherCAT, the signal delay of less than 100 μs and the integrated diagnostic function, process controls and automation solutions are always up to date. Because the solutions have to withstand harsh environments, an extremely resistant design is required. These factors, which are neccessary for a future-proof and high-performance solution, were implemented in the EC-DIO32 RM35.

The IO module EC-DIO32 RM35 was designed for a leading engineering company. In the beginning there was the requirement for the same IO modules, which the company has already used from Sontheim for CAN – but now for EtherCat. Sontheims development division made the innovative proposal of the EC-DIO32 RM35 – which reduces downtimes and enables higher machine availability. This is possible thanks to its integrated and freely configurable variety of different inputs and outputs. Using a selector switch, the desired configuration can be selected that is 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 errors.

Benefits

The integration of the two fieldbuses CAN and EtherCat enables machine manufacturers to easily switch from CAN to EtherCat, if higher bandwidths are required due to increasing demands on machine equipment. Nothing must be changed at the existing IO modules.

The EC-DIO32 RM35 speaks both fieldbus languages. This saves high conversion costs and a lot of time. In addition, the factor of freely configurable switching blocks and the selection of the required IO module via the selector switch enables a new level of modularity.
