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.
