Thank you Celichi for your quick reply. We were able to test it on site yesterday. There didn't seem to be consistent results from switching PLCs. Probably the SLCs and the HMIs are not on the same network. Below is the report from the commissioning team:
After changing the message to have the IP address of the HMI server, a few times, communications were gained instantly with the HMI. However, the last three times we switched PLC’s, communications were not gained instantly. As we were in the process of switching, it seemed that the old MAC address would remain in the routing tables, but after sending the MSG manually a few times, the new MAC address would appear. Even with the new MAC address in the routing tables though, The customer IT still could not ping the PLC’s from the network.
Below is the IP information:
The PLC’s have the following:
IP: 10.207.36.13
Subnet Mask: 255.255.255.0
Gateway:10.207.36.1
HMI01:
IP: 10.206.66.103
Subnet Mask: 255.255.255.0
Gateway: 10.206.66.1
HMI02:
IP: 10.206.66.104
Subnet Mask: 255.255.255.0
Gateway: 10.206.66.1
