Hey all,
I posted here a few months back, and eventually talked my company into letting me research the advantages of using PLCs instead of relays. Someone here showed me the Click! PLC product, and we went with that option.
I dove directly into the programming and I'm loving what I can do so far, but.. I hit a small issue. The Click! PLC programming tool doesn't seem to support resetting an off-delay timer. For my application, resetting this off-delay timer is crucial.
I've looked into possibly setting the current value of the timer to about a second or so before the timer would usually turn off; however, the technician at Click! said I'd have to reset the timer in programming and that's a little complicated.
I also thought about setting an input to set the PLC to STOP then RUN, maybe to reset my timers. Again, technician said that wouldn't be possible.
Can anyone help me think of a work-around for this? I'd really hate to have to purchase another PLC and start this whole process over again just because I can't reset the timer.
My application is more complex, but in a nut-shell this is what I need to do: An NO contact closes, it activates a bell for 10 minutes. A push button in the building is pushed and it turns the bell off early, before the timer is up. Basically, a kill switch that kills the bell short.
If anyone can help me, I'd be VERY appreciative.
