Now i would like to confirm from my nearest HMI that...is it other location HMI also communicating with same PLC or not. My question is more clear to u from attchment. Note: We can check other HMI network IP packets condition from Start - Run - Ping 10.235.10.5. But this is not enough.... we need to confirm that is it other HMI siemens runtime "send/recv connectivity" is healthy or not. Thanks in Advance.

This is just a suggestion from me which you may try and not recommended.There may be other methods too
