Hi all, I'm new on this forum. I'm learnig programmin siemens LOGO.
Now I'm wotking on hydraulic waste compactor. If anyone could help me with logo program?

Details of inpunts:
I1 - signal from contactor (after start button press it's hold Q1 out signal for contactor)
I2 - start button signal (one press start cycle)
I3 - limit signal from hight positon (after short signal change direction)
I4 - limit signal from low positon (after short signal change direction)

Out:
Q1 - contactor to engine
Q2 - push forward
Q3 - push back

Note: After press start button it will make 3 cycles height/low position and thene turned down. One cycle takes about 25seconds.

Thanks

Thanks for You answer. I don't know how exactly make counting model that change direction after signal from limit sensors I3/I4 which change outputs between Q2 and Q3 (push and turning back of hydraulic).

And how to make 3 times repetable process (3x push forwad, 3x turn back).

Old logo computer die and can't upload program to PC :(

maybe something like that ?
