WinCC Modbus TCP problem

Hi guys,

Inmy recent projectI want to connect Siemens Sentron PAC3200 devices to the WinCC V7.0 SP1 via Modbus TCP. Using standard Modbus TCP driver in WinCCI established communication andI'm are able to read from PAC (from holding register, function code 0x04).

Obviously something is wrong with addressing but I'm not sure exactly what. Also I didn’t found any explanation about file parameter in address properties, fig.1.

Please can you give some advice how to solve this issue?

P.S. I’m using PAC3200 device with latest firmware version (V2.1.0).

Kind regards

Alen

Hi,

I have the same problem, is there a solution for this?

=> in the meantime I found the solution, you need to use "4x Holding memory" instead of "6x Extended memory". The offset is %MW 60004. 

Kind regards

With a signed 16-bit value and address 3x60004,

Writing 0 will reset all the energy counters.

Note: 'Borrar_Sentron" translates to "Erase (or reset)_Sentron".
