LWE button switch depending on operating conditions

I have a problem that I can't solve on my own

A switch button turns on a motor.

When the engine turns on, the switch button become red

that signify that the operator can turn off the engine whenever he wishes.

but ... in the event that the operator forgets to turn off the engine,

I would like to include a countdown timer so that the engine turns off on its own after a while

the problem I have is that if the motor stops at the end of the time delay,

the button stays red and does not turn green again on its own.

I can not find a way to send a low output to the variable at the end of the time delay without maintaining a high output before which interferes with the input of the switch button.

Thank you very much for your advice.

PS . It's a bit the same problem that I had previously with analogic values

actualise parameters with LWE and LSC - Entries - Forum - Industry Support - Siemens

which had been solved via VM mapping but in this case I do not believe that it is possible.

thanks again

In attachment the example.

Thank you very much for your help and your time.

It works very well and the code is very clean.
