Hi there,

Is there a way to do a two way communication between PLC’s using DigiMesh?

I would like to read/write variables between PLC1 and PLC2 wirelessly.

Best Regards,  
Damian

That is nothing more than connecting Tx and Rx lines. Then set the DL and DH accordingly.

What hardware should I use to do it? I mean hardware from digi components.

Should I use two of Digi ConnectPort X2 Gateway?
