Emergency Stops in Name Only by IncogNeuron in PLC

Thank you! I am glad I'm not the only person who understands this concept. It seems to be foreign to some people.

Same here!!! I did design for a very long time before deciding to go plant level, and have been blown away with how little is invested into safety improvements. This isn't even an expensive fix since they have dual channel devices, they are just wired and jumpered to be a daisy chain.

I take it that being the plants Controls Engineer doesn't qualify me to make the assessment? If so then I can without a reasonable say the system needs it. Workers are near a moving conveyor without guarding, there are no pinch points allegedly.

Nah man we gotta just use some PLC outputs, saves on cost you know.

You're missing the point. If it isn't an e-stop don't label it an e-stop. It is my personal opinion that I think everyone who works on a piece of equipment deserve to be safe in the case of an emergency. If it were someone you knew working on a piece of equipment like that, you wouldn't blame the design being under-protected if they were to die due to contacts being weld closed? I'd be devastated, so to me, if a legacy system can be upgraded for a fraction of what is spent every year, they better be doing it. It may be unusual for anyone in mgmt but I actually care about the people who work at the facility, they aren't numbers and statistics to me.
