Write the following PLC Program to Energize or De-energize the Outputs based on Events.

A certain switch (I:1/0) is to start a process.

The process is to run for 30 seconds, stop for 10 seconds and then repeat as long switch I:1/0 remains closed.

Opening I:1/0 at any time is to reset all timers and de-energize all outputs. Output O:2/0 is to be energized during the 30s run period and output O:2/1 is to be energized during the 10s stop period.

During the run period, a single output O:2/2 is controlled by input I:1/1. If I:1/1 is open (at the beginning of the run period) O:2/2 is to be off for the first 5 seconds then on for 10 seconds.

If I:1/1 is closed (at the beginning of the run period) O:2/2 is to be off for the first 10 seconds then on for 15 seconds.

Changing I:1/1 after the run period has begun should not change the above sequence. Output O:2/2 is always to be off during the stop period.

    Hi, exactly what I’ve been searching for – Thanks.
    Is it possible to write it in STL? I struggle a bit with Ladder.

    Many Thanks.
