Hello All,

Im working on MODBUS project with s7-1200 plc. Also i have CP1243-1 Comm card for comminication between PAC3200 for getting energy datas. I use PLC profinet port modbus server with another plc and it is working. But when i use CP card port different ip block modbus client for pac3200, im getting some problems. When i check block modbus client status freeze on 16#7002.

I added config and block status on attachment. How can i solve this problem ? 

Thanks for helping.

Hello again, yes i checked that one. I can handle modbus with cpu PN port but, when i try CP card i they cant comminacate. Also i tried simatic wincc to CP card still same problem.

 Hello BORANI@FQML

which communication settings do you have activated in the S71234-1 in TIA?

I´m not sure but the WinCC communication should work with TSCB
