input to stop machine
« on: March 26, 2024, 08:18:07 AM »
We have a new machine and I am going to be putting a pressure sensor on so if the air pressure gets too low the machine will stop.
What would be the best place to put the code?
PLC Script?
Signal Script?
Any other place?
Open to any ideas.

Thanks,
Bill

Why not just wire it through the e-stop circuit.

If the air pressure drops slowly enough a pressure switch could signal the impending problem with enough time to stop the machine with the feed hold. This would allow you to continue once pressure is reestablished.

We use a pressure gauge that gives two outputs at different pressures.  We set a Low Air Flag that turns on the red light to the machine but allows the machine to run still, but the No Air Flag will e stop the machine.  I handle this code in the PLC Script.
