Hi..
i want to know the Ethernet protocol (Ethernet IP or Ethernet TCP or Modbus TCP or any other) of omron CP1L CPU. CPU part number isCP1L-EM40DR.
i searched in net, till i am not clear
The built in Ethernet port in the CP1L-EM can only be used for TCP or UDP. As Mark has said it uses the Omron FINs protocol.
If you are requiring Modbus/TCP or Ethernet/IP you can get a comm's adaptor for the top of the PLC.
