Remaining time for next cycle

Hello everyone! My first post here asking for your wisdom.

I need to compare the interpulse remaining time of two (actually more) Asynchronous Pulse Generator.

I need this because if the min interpulse of the two is greater than some time I will stop a Pump.

I been searching but I only found how to using in the message text module.

Thanks!!

Not really. The actual problem is the following.

I have three valves and one pump. Two of the valves are for irrigation and the third one is just to return water to the tank and let the pump rest. The pump is quite big so I don’t want to turn it on and off to often.

The Valve for irrigation (V1 and V2) works on cycles and they overlap some time, which is no problem, but if both are off for a short period of time, I don’t want to turn off the pump. If the remaining time for the next irrigation valve to open is to long, I will like to turn off the pump for that period.

Now the system is like the following attached.

Sorry my friend,in my first post I try to describe a very simplify problem of the same issue. Anyhow, my second post describe much better the actual problem.

I1 enables the first irrigation zone and I2 the second one. The thing is that each zone goes trough a cycle. During the interpulse (pulse off), the pump should keep running if it the remaining time for the next pulse is short., but if the remaining time for the next pulse is long I want it to turn off.
