NI OPC and S7200

[PBP]

HI i want to develop SCADA application for S7 200 PLC. I am using NI-OPC. I have connected S7200 PLC to Ethernet network through CP243-1 communication module. DO i need additional hardware to communicate S7 200 with NI-OPC.

Hey prashantpatel21,

All you really need it to connect to the network through the Ethernet, which you have already done.

Is the S7 - 200 Siemens device?

If so, it is supported and you should be able to create the tags to connect to the OPC server using NI OPC Server.

Do refer to Connect to Any PLC for further information!!
