we have two plc and three hmi connected throught ethernet and commuicating.Few days back we had to changed the old IP adresses of all nodes due to some problem.After changing IP one PLC is communicating with HMI but from other PLc i am not getting any data.
I changed IP address of PLC,HMI and in WinCC also.
How should i check and slove this problem?
