Thankfully at this point most of the repeat service calls I go to, the people there don't blame the program changing anymore.

The program doesn't change, but every once in a while I find that the program was wrong all along and just happened to produce the right results 99% of the time.

I've been a self-employed controls engineer for 37 years and people that I know well still don't understand what the job entails. I guess you have to see it to appreciate what happens.

I say "have you ever seen How It's Made?" if they say yes then I say "That." if they say no I say "I am a rocket scientist".

I once commissioned a system where, in hindsight, there was a tiny flaw in my communications structure. Basically, if there was a network failure that occurred after the PLC had completed executing one rung of code, but before it finished executing the next rung, it would fail to start communicating again once the network was restored. You'd think that with a relatively rare trigger like that (network failure), and such a minute window of time (we must be talking microseconds), that it would probably never happen.
It took less than a month after I left site for it to happen. So yes, the code doesn't change, but edge cases can lay dormant forever, or for no time at all! |

Given that I was called after everyone else had a go a "fixing it", whatever "it" was, I told people who asked that I was a janitor.

I say: I automate industrial machinery. Like JaxGTO, How it's made often comes up. Some people will say, oh, you kill peoples jobs. Basically

I know that what I do does. Sometimes we are so efficient we kill our own jobs. There have been multiple times where we sold the controls for a machine and we were suppose to sell 2 or 3 more and it didn't happen because the first machine performed so well. Our french fry machines replace 8 to 20 people.
