Reset Timer In Micro810 CCW

[gbradley]

I am trying to create a timing circuit to compute Instantaneous Pcs/minute.
I usually take 6000 and divide it by the elapsed time between pulses to get Pcs/Minute
I then Reset the Timer for the next pass.
So I am trying to do this with a Micro810, and I can’t figure out how to Reset the Timer.
In RSLogix it is the Reset Bit.
Any suggestions?

According to CCW help file. The falling edge of the input stops and resets the timer.

Oh.
I don't know how to do that.
I was hoping to start a Timer when the flywheel passed a prox switch, and then the next time it passed it, log the time, and then reset the timer at the same time.
If I could somehow reset the time, I'd be in business.

Just one-shot the prox and use that one-shot to drop the input to the timer AND move the timer accumulated to some location for evaluation.
There's going to be a lot of possible variations on this theme.

I don't think the OP has been waiting the last five years for a solution.

I'll say...
I should have replied back in the day when I figured it out. (or someone else figured it out for me :site
I think I used a Pulsed input.
Anyhow, I think that project has been happily running for about 5 years now.
