Hello!
I really hope that somebody already used that and can help me.
So i have Siemens S7-300 - Pn/Pn-Coppler - EL6631-CX2020
I configured everything already in TwinCAT but i d nto know how to read data. Siemens side is sending some BYTE and I want to read it. I tryed with adding INput in API but i do not get any information.
Anyone already did that and have any ideas?
Thank you
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I Don't know about the codesys side, but already done a pn/pn coupler.
First of all, each declaration should be mirrored : If codesys PLC is 1ByteIN/0ByteOUT, your other PLC should be 0ByteIN/1ByteOUT.
Once you get that correct, leds on pn/pn coupler should be all green.
If you are planing standard cyclic exchange, it should be enougth. (not for profisafe)
