Dear All,

Now I am doing a project with S7-1200 Siemens PLC.

I am new in S7-1200 (TIA Portal V15).

I want to write a program to run two numbers of pump in alternate with time.

firstly pump 1 run , after 1 week pump 1 stop and  pump2 will run automatically

After pump2 run 1 week,  pump 2 stop and pump1 will run .

This process will be continuously.

Please kindly advise for this.Can I get any sample pgm?

Thanks you all.

Hello,

you can use a Organization block for the time-of-day interrupt .

The OB can have the parameter weekly (call weekly).
There do you change a boolean variable every week.
