Linux 6.2.11 interface with plc automation cycle

I have build 2 small automated part loaders to feed a cnc machine. When the CNC mill has completed its task i need it to say I'm done yo go to the PLC. When the PLC has completed its task I need it to I'm done you go to the CNC. Please help me.

Hi. I would use the digital output/input mcodes (m64 m65 and m66 i think) and add this in the g code program to macjine the part.

You can the repeat the entire program using an o-word routine in which you initiate the plc with m64/m65 and wait for the confirmation with m66.
