[?]: Communicate 2x S7-226 via a cable with PPI protocol

Post by kamenoff »

Hello, I want to ask whether it is possible to take place.
I have 2 PLC Siemens CPU-226, which communicate via a cable with PPI protocol on RS 485.
My idea is to remove the cable and to implement a wireless link between the two controllers.
The maximum distance between the two controllers is 40 meters, they have direct visibility.
Thanks in advance for any advice and ideas.
Have a nice day. :)

You better stay with WIRED solution, I do not thik that PPI timings will pass RS485/Wireless bridges.
Weidmuller has such bridges, Phoenix Contact and Anybus too, but it is only for freeport RS485, not for PPI as it seems.
