Might have misread this. Are you talking about the home position limit switch with conveyor tracking? The limit switch that resets the encoder back to 0?
If so, I have never had to rewrite anything in the ladder for it. I remember a project where my robot job was resetting the encoder and I didn’t have a home position limit switch. I might have written something in the ladder for that project.
This was what I was talking about I ended up figuring it out all I had to do was map the input of the home position limit switch which was #40700 to my PLC input which was #00953 and then I tied that to a photoeye checking for hangers. Thank you!
