Working on my second CLICK project that involves counting sensor pulses from a cable winch to determine position. Currently hoping there is a way to do this with a single sensor and the correct logic. I can easily set a counter for the "Up/Raise " and "Down/Lower " however if someone is to hit the stop button in between and then reverse the direction I would run into issues. What would be a good way to write this program? I assume it would need to store and compare the counter value based on which button is pressed? Or will I need to do this with two sensors so that it can determine rotation? I do have a hard reset via limit switch for when the winch reaches the very top. Thanks.

How fast is this winch going to activate the sensor (pulses)? Does this CLICK have anything else to do?

Hey Todd, I can post/attach again.
gotta wait 13 more seconds to post again, so I'll type a bunch of garbage in to waste that time!

Awesome!

I like this one better. I don't know why I thought interlocks were a good idea.
Edit:
Kewakl has a point; how fast will you be sending pulses to the Click? Depending on the frequency, the Click "may " miss some pulses. If the Click is too slow, the BRX plc is your next best bet.

Based on your response, I coded the attached.
I don't think what your asking is troublesome. I have a pool cover I'd like to do the same to, as the manufacturer had a less than robust control set-up.

Thank you for the help, I went a different route in the end, but still appreciate everything!
