Hello Experts,

I want to communicate InteliMains Base Box IM-NTC-BB (Power Drive System) over Modbus TCP/IP with WinCC V6.0. The problem is I cannot find Modbus TCP/IP driver in WinCC, How can I add this driver ?  Please Help me. Thanks

Jack.

Hello jack_lohana;

There were no available  Modbus (RTU or TCP) channels in WinCC v6 provided by Siemens.There was a Modbus RTU channel in v5.2, but it was developped externally by Allmendinger, and it did not renew its partnership with Siemens as per version 6 of WinCC.

At this time, you could buy a license for Modbus TCP (or RTU) directly from Allmendinger, which can be integrated in WinCC v6. See the following link (and check the supporting OS versions of Windows):

The other option would be to use your PLC to exchange as a client over Modbus TCP with your server, and transfer the data to WinCC through the integrated channels of WinCC 6: MPI, Profibus, Ethernet.

See this discussion, based on a Siemens PLC:

Hope this helps,
