Hi,

Is it possible to to read and visualize PAC3100's parameters without specialized RS485 modules for S7-1200 in TIA v19? 

I have RS485 to USB gateway, and I succeeded to read PAC's parameters using Modbus Poll app (Modbus RTU).

Can I manage to read PAC's parameters on HMI TP700?  If it is not possible in TIA v19, is there some other solution for this?

Thanks

Hello milos23

I only know a direct connection to WinCC V7/8/Professional:

But I never tried it with a Comfort Panel directly.

You could try in the same way but unfortunately I do not know if it works.
