Answer question
HPG800 Modbus TCP redundancy fail, In same IP address, Hot standby.
1.Please refer attached network schematic.
2.At both yokogawa Client module(A/B).
We set Server information to get modbus data.
and set same ip address(MAIN server/Back-Up server) at both yokogawa module.
3.Client B is not working until network A(Main server) would be dead.
Only Client B start working when network A is down(Back-up server start working instead of Main Server by same IP address of Main Server)
4.As per my knowledge, HPG shall works as dual in normal operation. means Back-up server also shall works always.
5.If I have to change IP configuration, Please let me know where and how I can change
