I've been poking around on the net to find an answer to this question but haven't been able to locate a definitive one.
When using a e-stop monitoring safety relay with hardwired maintained e-stop push buttons is it permissible to use a PLC relay output to ultimately supply the momentary reset signal to reset the monitoring relay once all the e-stop buttons have been reset (manually pulled out)?
The thought is that pressing a button on the touchscreen and using a PLC contact to reset the monitoring relay ensures functionality of the touchscreen and PLC program to allow the resetting of the monitoring relay after an e-stop.
