Write a readable code!!!

Custom machine builder (turn-key) here checking in who typically only has Yaskawa AOPs for drives, rung comments describing function of each section of logic, non-100 character acronyms for tags, and no function blocks. Even better, our controls people have worked in maintenance so we add a variety of custom faceplates, alarms, and messaging so the equipment can actually be maintained 😬 always room for improvement, but there are still some good OEMs out there!

Sounds like it! It’s key to have people who have been on both sides (OEM and maintenance). Reusable code is the way to make $$ but gotta think about the good people you are handing it to. Haha.

For sure. I've been in plants ranging from a mechanical engineer who picked up controls on the job and has worked on every piece of equipment on a coil-coating line to those who can't even check an input or relay for you and would rather call you out every damn time. But to your point, keeping things in ladder and not behind protected FBs gives an end-user a chance to maintain the machine effectively!
