Gate hits limit switch
limit switch signal does not act directly on contactor signal wire but goes into PLC through Ethernet and PLC switches motor OFF.
Problem - gate running past limit switch because of processing time.
My fix is to have the limit switch interrupt supply to contactor and to also supply feedback to PLC via a double pole relay.
My Boss (Dad) thinks the control should go through the PLC.
Digital signal in for the limit and
Digital signal out to stop motor
If anyone can help clarify this issue would be greatly appreciated.
