Hi,
Is there a way to make 2 SLC 500 communicate by RS232?
I need to exchange some data between them using.
One is on the second floor or a building and doesn't have an ethernet port, and the other one is in the basement and does have an ethernet card.
Any schematic of cable or other would be appreciated.
Thanks

If your both SLC has DH+ ports it will be more smart to organized the link via DH+ net.
You can use MSG instruction for it.

Yea but one of them is a 1747-L551/C with ethernet and rs232 port only. Since the customer don't want to change the others processors to ethernet ones, i need to be able to connect by rs232.

Found an easy solution.
Use MSG messages on the source PLC, working great with 2 Sena LS-100 over ethernet, PLC think that it's communication with an RS232 port.
