Ten guys with laptops
I had ten guys that worked for me in a plant and they all had laptops. This was back before any software managed checks and things were saved to floppies. We had a rule if you changed ANYTHING in a program you put it in writing.
Who did it?
Who asked for it to be done?
Why YOU did it.
How long is it going to be that way?
If we went to work on a machine and it had a force on it if it was not TAGGED on the controller forces were removed.
If you went to work on a machine and the backup did not match the machine and there was not a temporary floppy at the processor you reinstalled the backup program.
Backup floppy’s ONLY had working programs not any temp fixes.
When you had 100+ PLC 2s and PLC 5s and SLC500s you could not put in patches and expect them to be taken out all the time. So it was no permanent patch for more than 2 weeks.
