Does anyone have a Micro-Win Subroutine that will alternate between 2 pumps?

 

Hi
Could you supply a little more information?

When should it switch(temperature, pump fault, etc)?
Do you already have a S7-200 CPU?
Has it expansion modules?
How should the output work(A0.0 pump1, A0.1 pump2)?
Frequency convertor (analog output 1/2)?

I can write your program, + prove with webcam that it will work, I have my own PLC lab.

 

Have a S7-226 PLC with TD-200 display. The situation is I have 2 pumps. Each time a pump start is requested, I want to alternate between.
ie, start pump1 on first request, pump2 next, pump1 next, pump2 next, etc.

Any help would be greaty apreciated!
