KepServerEX OPC Server communication problem with Siemens S7-300 PLC


Thread Starter


Dear all,

I am having Siemens S7-318-2 DP PLC with CP343-1 lean Ethernet module, which I want to use with KepServerEX version 5 OPC server. Now, in driver configuration it asks for PG/PC/OP link type. Since, the mentioned PLC supports PG/OP communication, which option I should select for successful communication with the mentioned OPC server? Your help will be very much appreciated.

P.S. : Simatic Manager and OPC server are on different PCs.
