How to exchange data between two omron PLC through series communication

[seanshen]

I have two Omron PLC CS1G, located in different place, need to exchange few data through a existing RS422 line. I have SCU41 card for both PLC. Has anyone done similar project? Two PLC directly exchange few data. Thanks

Welcome to the forum.

Take a look at PLC Link.  Depending on how the RS422 connection is currently being used.

Also take a look at Network SEND and Network RECV.

Hope this will help.

I would use controller link to share information between the controllers.
