Course Content

To fault find a system you need to know exactly how it works.

How exactly does a PLC work?

  • The LED on the output card means I am getting voltage out right?
  • What exactly happens in-between? Theres 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?
  • Is forcing a bit and toggling a bit is pretty much the same?

How do I do the following?

  • S7 family hardware (basic specifications).
  • Basic hardware troubleshooting.
  • Theory of operation.
