I worked at a paper mill that had very limited systems maintenance engineers. One guy in particular once saw an electrician fix a logic loop lock-up by rebooting the local device IP address instead of doing an on-line edit or fixing the logic off-line and then upload.

The engineer did a download of the existing program to solve his problem to clear the locked up logic.

There were large parts of very large machines as far away as the parking lot.

"Button pushers". Management loves them because they never know enough about what they do to explain bad news.
