Hello,

If you are interested in automation technology with PLC (programmable logic controller), here is a little document from me.  
I tried to implement a PLC in Node-red.  
The logic behind it is not immediately understandable at first.  
But almost all automation systems around you work like this (e.g. production lines, elevators, etc.)

This is pretty cool. Which node package did you use with this?

This is the first time I have encountered this. I will have to play with it.
