How to Reset a Timer in CX Programmer

3 posts in this topic

Can You explain me how can I reset a Timer so that after completion of the cycle, it automatically starts again from 0 sec in CX Programmer? I am working on a program for a Oxygen PSA Plant. In which the valves of 2 cylindrical tanks switches at a specified interval and the cycle keeps on repeating. Thank You.

The logic in front of the timer needs to turn FALSE to reset the timer.  Many people will use the completed output as a normally closed contact on the input so that it resets itself each time it ends.

Another possible methods:
- Use CNR/CNRX instruction.
- Write desired time preset value into the timer, e.g. with MOV instruction.
