Hi PLC'ers,
I've written a little ladder program and it is working quite well.
How do you typically apply an E-Stop function into the logic ( or hardware) ?
Someone mentioned just killing the 24vdc to the unit but I'm wondering if there could be 1 control bit that would stop the scan and put the unit into STOP mode until it is reset.
Another thing I'd like is to be able to have 1 input to PAUSE the execution of the ladder at any point, then another to RESUME.
Or similarly, something like Mach's Single Step mode.
Thanks again,
Russ
