WinCC Communication

Is it possible to communicate from an HMI of Siemens WinCC (7v3) to a PCMM via Modbus TCP/IP driver?

The Modbus WinCC communication driver requires on the a CPU selection between:

- 984 (Use this CPU type for the CPU 984 (except for CPU 984A, 984B and 984X).)

- Modicon Compact, Modicon Quantum, Modicon Momentum

- Modicon Premium, Modicon Micro

Which is the correct configuration?

Thanks for any help

Sorry for the late answer, I tried to find a printable WinCC Manual without success.

I just can send you some printshoot.

I tried the communication as 984 and Modicon Quantum with different types of read/write (coils/registers) without success.

Here are the general Modbus TCP/IP settings for mating a HMI to the PxMM Controller. Please consider these when setting up the HMI.

Note: PxMM can be a Modbus TCP/IP slave only

Also here is a link from the PxMM manual with information on a Modbus TCP/IP communication setup

Hello Dome,

Can you please send the Modbus TCPIP help file that you referenced. We need further information to determine best possible approach.
