Overview
Our drives support almost any Industrial Ethernet, Fieldbus or real-time servo network such as Ethernet/IP, Profibus and EtherCAT. Where possible, we obtain independent certification for compliance with the relevant protocol standards to guarantee operation with other vendors equipment. We continually monitor our customers needs and develop new modules as technologies emerge.
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.
