Hello Yasin, Thank you for this video.
I have a problem with preset controller Honeywell FUSION4 MSC-L;
5 Fusion4 MSC-L are communicate with WinCC 7.0 Siemens via Modbus TCP/IP. Each Fusion contain 2 ID slave to read particular data under each slave. The WinCC communicate with each slave via different Ethernet port (different IP address).
Sometimes, one or more Fusion4 diconnect for a while and reconnect again (the time to reconnect is not always the same). The Modbus TCP/IP communication is not stable.
I have a wireshark file. I need to found the problem. Can your help me with this ?
Thank you very much !
