"Hello,

I'm working on a project with a Siemens LOGO! where a certain process should only start if a door is closed. I want to detect this using a push bottom, so when it is pushed the door is closed and the proces can start

If the door is not closed when the process is supposed to start, I would like to generate an error message (with a light)

Does anyone have  tips on how best to implement this in the LOGO! programming? Any help is appreciated!

Thanks in advance!"
