3 PUMP SEQUENCER

[srd]

Anybody got a program for a 3 pump sequencer i can look at, i have 3 on positions and one off. As the level rises it will operate a pump at each level if required and pump down to the off position which will turn of all pumps and activate the sequence start for the next time the pump start. If in LD would be helpful. Cheers

Hello srd, maybe this is an example you can work with.
The user defined function block within the demo program calculates the pump out of three with shortest operating time.
This information can be used to always start a pump with the shortest operating time.

PS: Don't forget to make C01..C03 as retent in UF parameters.
