I used to do a lot of programming in the late 80's siemens and AB.

The tablets I'm taking have not been kind to my overworked brain

During Furlough i decided to make a watering system the wife has be going on at me for .

Thought I know i'll use counter but the  0BA2 doesn't support them :-(

all i want to do is drive 4 pumps for 2-3 seconds sequenced 

Weekly timer outputs to pump 1 on for 3 seconds then off

pump2  on for 2-3 seconds then off

pump3 on for 2-3 seconds then off

pump 4 on for 2-3 seconds then off

run process again till 30-35 seconds

put output 5 on then run the sequence again for another 30-35 seconds

wait for next output from weekly timer

Ladies and gents any help would be appreciate for an old man.

Realy a 0BA2?

The 0BA2 has a max of 4 outputs, you and i, cant make your wishes, ther is no Q5!

The 0BA2 has  counters

Thanks for the quick reply

I'm using a 0BA2 long with 12 inputs and 8 outputs.

I was hoping the 0BA2 had  on threshold and off threshold for the counter so i could pulse it at 1 second intervals.

the reason why I want to use o/p 5 is the pumps i'm using are 12 volt washer pumps with 2 outlets so if I run the pump in reverse polarity it outputs water on the 2nd outlet.

i'm using a weekly timer to turn on and off the sequence

output from weekly timer  run pump 1 for 2-3 seconds

1 second no outputs

run pump 2 for 2-3 seconds

1 second no outputs

run pump 3 for 2-3 seconds

1 second no outputs

run pump 4 for 2-3 seconds

1 second no output

turn on Q5

run pump 1 for 2-3 seconds

1 second no outputs

run pump 2 for 2-3 seconds

1 second no outputs

run pump 3 for 2-3 seconds

1 second no outputs

run pump 4 for 2-3 seconds

1 second no output

Finish

Hallo Shrek66, try something like the example in attachment. This is a possible solution for you.
