Hello Tim, thanks for the amazing work you're doing with this!
I have a question regarding the sample rate timer DN bit. Why is it that having it as an XIC makes it look like it is perpetually on? Shouldn't the timer stop counting because the DN bit turns ON?
For example, we start with XIC and a timer counting to 1 sec, when it counts to 1 sec and the DN bit comes ON, shouldn't the XIC SampleRate bit turn OFF thereby stopping the timer? Is it restarting because the program itself is restarting? I'm quite confused

[@TimWilborne]

That is an XIO (Go look for a 0) in front of the timer. It looks like it is continuously on but when the ACC is greater than or equal to the PRE, it will write a 1 to the DN bit. On the next scan, when the XIO goes and looks for a 0 in that DN, it will see a 1 and be false. A false TON writes a 0 to everything but the PRE which includes the DN bit. On the next scan, the XIO will see a 0 and be true, starting the timer again.

​@@TimWilborneThank you very much, that's really helpful to know! And I accidentally flipped that (XIC = Examine if Closed), I am looking to learn all of this so I appreciate your videos a lot. Again, thank you!

Sir how to count seconds in logix plc ? Any video on it ?

[@TimWilborne]

RTO?

[@kgauravb]

@@TimWilborne yes as I want to count the seconds of different operation in a machine and that should be retentive for that particular cycle and should get reset after a given set condition.
