S7-1200 can not connect to the PAC3200

derirgendwas Posts: 2 Rating: (1)	Hi, I am having a similar problem. I am trying to read values of a current measured by a Sentron PAC3200 with a S7-1200 over Modbus TCP using MB_Client. Somehow the S7-1200 can not connect to the PAC3200. I keep getting "Error" and Status Value "16#80A4" (see attachments). What is wrong? PAC3200 has IP 192.168.1.3 The value I am trying to read is Offset: 13, number register: 2 (current L1) Please also see the attached screenshots. Thanks a lot for the help. ------------------------------------------------------------------------------------------ Split from s7-1200 modbus tcp client communication problem.

What is IP of your PLC?

What is IP of your PLC? Hi Duris_I Thanks for looking into it. The issue is resolved for now. I simply adjusted the IP of the PLC so it matches the subnet of the PAC3200. Problem solved. Best
