Hi, so I build the electrics in my home with 5 Logo8 PLCs, which work fine so far. Now I want to connect home assistant on a raspberry pi 5 to those PLCs via Node-Red.  
I followed a few tutorials for this connection, but I cannot get the switches from node-red to send a signal to the plc... I attached all the screenshots from the configurations...  
I hope somebody can maybe send me on the right path so that I can debug this...  
Thanks!
