you should specifing the type of the I/O 's ( sinking or sourcing ) if the inputs are sinking the commun will be the 0V and the plc will receive ( from the push button or any digital sensor ) the 24V as an input and if it sourcing the commun will be the 24V and the plc will receive the 0V as an input .
Great suggest! This is one of my older videos and I plan to start remaking them because TH-cam wasn't the intended purpose back then. I plan to communicate everything in more detail in the future.
I always use a safety PLC/controller / relay . 2 chain circuit. The keyence GC 1000 is great for e stops and light curtains. This is ok for very basic controls but not really good for industrial applications
I believe the residential grid is set at 117.5v +/- 7.5v. Most electrical devices operate between 110v and 130v but that's not a standard. I just grew up calling it 120v because that's what my teachers called it. Sorry for the confusion.

i encouraging you to make it. because it will be useful for people to understand this basics and good luck.@@Mikesfilmss

What is a 2 chain circuit?
Great!
Why do you say 120 volts but in the schematic it says 115?

@@Mikesfilmss ah ok thanks for the clarification.
