I have a situation, if you can help me. ( If I had posted in a wrong section sorry )
I have something like in the attached picture.
At the end of the cycle, M1, M2, M3 are reseted ( goes at OFF status ), they are made ON ( if is the case ) within the cycle time.
The problem is, when the status of M4 goes ON at the end of the cycle and in the same time, M1, M2, M3 are reseted, the program goes at rung 0, and the rung 1 doesn't come to be made. M3 doesn't have time to be maked ON during the program cycle because the programe resets M1,M3 and M3 and the branch 0 it is maked first.
Plese help me to solve this problem without timers.
Thank you very much.
