I am working on an application in which my robot (a Fanuc LRMate 200iD) is controlled by a PLC (via IO signals send to the R30iB mate controller). I want to send an E stop signal to the robot via my PLC.
Since the external E stop uses a Normally Closed 24VDC signal i hoped that simply connecting pin EES11 and EES21 to an output pin on my PLC (also 24VDC) would do the trick. By having the pin being always on (except if i want to E stop the robot) the robot can run, when the pin goes low (when i want to E stop the robot or the PLC goes into E stop) the robot will stop. Apparently this doesn't work (or i did something wrong) seeing as i blew a fuse when trying this.
So my question is as follows; is it possible to use my PLC to give the robot an E stop signal?
