Communication

SM-Ethernet
Our Ethernet option module supports Ethernet/IP and Modbus TCP/IP; it has an inbuilt web server and can generate emails. The module can be used to provide high speed drive access, global connectivity and integration with IT network technologies such as wireless networking.
