I also have a reset question along this line.

I'm also using an 05 in a high speed counter operation but I would like to

reset the counter internally after my CMPD has reached my preset value.

Everything works great when I reset the counter using an external input

like a prox switch. Does anyone have any suggestions how to reset my

counter internally after my CMPD has reached its preset value?

Your help is greatly appreciated.

Thanks

05 Counter reset

Thanks for the reply,

I 've tried a few different ways to reset the contact placed on that rung.

I'm using two CMPD boxes after the counter. I can successfully generate

individual outputs from each CMPD as they reach their individual preset.

After the second CMPD I would like to reset the counter which is driven by

an encoder. It appears I need to use input X2 on my PLC as the reset contact

and input. Is there a virtual way to turn on this contact without using an

actual external input such as a prox switch? I would like to reset the counter

after the second CMPD box has reached its ' preset.

Thanks for your help

You would use the external contact when there is a detectable event (the switch being hit by something for example) where you want to reset the count. The setup of the counter function allows you to choose if you wish to use X2, with or without an interrupt, as a reset.

If you don't have any external event as a reference then just set that to 'filtered input '. Place a control relay contact (which is driven by the result of your compare) in that third leg instead of (or in parallel to) whatever else you have there.
