  • Be able to backup and restore a PLC program when required
  • Be able to perform basic system diagnostics when a problem occurs



1. How Exactly Does A PLC Work?

  • The Led on the output card means i am getting voltage out right? does it?
  • What exactly happens in between? there’s more than just a program in the CPU
  • How exactly does it scan the program?
  • What is this Watchdog Timer? Is it that important?
  • Can I use the same output twice? That’s bad programming isn’t it?
  • A PLC is a logic controller, so use a logical approach to fault find it
  • What are the 8 simple test points to check?
  • The PLC is in RUN, that means there’s a program right? does it?
  • FORCING a bit and toggling a bit is pretty much the same yeah? depends on which PLC
