Communication of PC with Compact HMI 800 with two different completey isolated AC500 PLCs
We have to communicate one CHMI800 to two different AC500 ETH PLCs.
The same has to be treated as two completely isolated systems/plants.
Only one RJ45 Eth port is available in the computer. We have got an eth switch 5 port which can be brought into operation.
Please let me know the settings i have to configure so that I can accomplish this.
Awaiting your help.
In your case most probably the both PLC's should be connected in same network area with different IP and same subnet mask.
In the same network have to be connected the CHMI800, with installed in it OPC server for AC500 on it.
E.g. PLC1 = 192.168.0.10/255.255.255.0, PLC2 = 192.168.0.11/255.255.255.0, CHMI = 192.168.0.20/255.255.255.0. That means 3 ports in the switch
Then in CHMI you have to connect to both PLC's, exchange the tags using OPC and prepare the visualization, as required.
