I need to setup a zone on my fanuc that while inside the press is unable to close. I need this to be monitored at all times. What is the best option for doing this? I have read about the variable $SCR_GRP[1] $MCH_POS[] but as i understand it this function only updates while in auto mode. I need this to be monitored %100 of the time. I am coming in behind two different programmers that had a hand in setting this workcell up and neither are available any longer.
Ultimately i just want to send an out put to my PLC that the robot is inside the press so that my PLC can send the signal to my press and block the press from closing and i need this to be done in manual and auto.
Any suggestions?
