The "Imaginary Relay" Problem, Part-1 of 2

I just put random instructions together and get the FAT guy to fix it.

Yes, I do call myself the FAT guy when running a Factory Acceptance Test.

Do you call the PLC the FAT Controller?
 
For folks that INSIST that the method that helps them understand a concept is the best way for everyone, I say take a deep breath. Different people learn and process information differently. To some people the XIC/XIO construct does a better job explaining the concept. For others the relay model is more intuitive. As far as I'm concerned the universal perfect model has yet to be invented.

Agreed.

My head works in relays. I insist on using that for myself. Everyone should use what works for them. I insist they shouldn't insist I change. 🍻
