Course Content

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

How exactly does a PLC work?

  • Am I getting the input to the PLC?
  • 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?

  • Check power is ON and PLC is in right mode (RUN or Program).
  • Check LEDs for fault definition.
  • Check and change modules if required (with spares and without spares).
  • Removing modules with power on.
  • Establish link to PLC (RSLinx).
  • Link to CPU via RS232 port, Ethernet or DH+ module.
  • Checking Ethernet connections using PING instruction.
  • Create a blank project and take a backup.
  • Open the correct project offline and link to PLC.
  • Interrogate errors in controller properties, common faults.
  • Identify if it is a hardware or software fault.
  • Identify if it is a PLC or comms fault.
  • Access fault information about IO cards.
  • Change the battery, with power on.
  • Working with CPUs with non-volatile (EEPROM) memory.
  • Check all settings against a template, node address etc.
  • Check hardware configuration, IO errors.
  • Clear memory and download program.
  • Monitor program
  • Is it latched or unlatched?
  • Altering values in tag tables.
  • Back-tracking through a program to establish where power flow stops.
  • Searching for specific operands and instructions.
  • Using bookmark function.
  • Changing timer, counter values online.
  • Making minor mods offline and online.
  • Create a trend-to-trend address status or values.
  • Altering timer, counter and other values if required.
  • Force a parameter if required.
  • Toggling addresses to move program on in sequence.
  • Call up documentation to assist with software diagnostics.
  • Printing cross reference / program listings etc.
