On and Off Delays

(1/1)

sdietsche:
For a conveyor application I am running a sequence that moves the conveyor forward for a time, lets it sit idle for a time, and then finally runs it rearward for a specified time. To do this I am using two on delays and an off delay. My issue comes into play when I manually shut the sequence off and then within seconds restart it, the previous sequence is still running its course and with the addition of a new sequence I just initiated. My question is, is there a simple command to kill or reset the on and off delays given a specified Boolean signal?

Thanks,
Scott

Neil:
Hey Scott,

have your on/off delays control latches with a combination of transitions, see an example below.

regards Neil.

FluidPowerTom:
Another method is to use a smaller time base - such as T100M - and have a manual shutdown of the sequence switch the time constant to be '1'.  This would make the sequence end in about 100 ms after a manual stop.
