SEND Block Using IP Router Table

[BobAloVskI 0]

I am trying to send data between two Omron PLCs using the SEND block. PLC1 is a CS1G-CPU45H with a CS1W-ETN21 Ethernet Module. PLC2 is a CS1G-CPU43H with a CS1W-ETN21 Ethernet Module.

 

PLC1 has an IP address of 10.60.34.22. PLC2 has an IP address of 10.60.66.23. They currently both have subnets of 255.255.255.0 with Network Addresses of 22 and 23. The examples I’ve seen mainly deal with both PLCs on a class C network, but what would be the best way to get these PLCs to communicate to each other with their IP addresses?

As the IP Addresses are not near each other, I don’t think I can use the IP Address Table. I think I need to use the IP Router Table instead. I can add the gateways to each PLC’s IP Router Table easily enough.

Do I then need to add an IP Address Table entry still? Do I need to add entries of 23/10.60.66.23 and 22/10.60.34.22 into their respective PLCs? Will it affect anything if both networks have PLCs with Network Addresses of 22 and 23? 

Any help with this is greatly appreciated
