“The software is working out great. It’s worth making sure that our new maintenance people go through the programs and now it’s going to be a mandatory part of their training. I’ve seen the difference in the few people I’ve run through. The more practice I can get these new troubleshooters the better.”

The simulations

Develop and master your troubleshooting skills with three unique troubleshooting scenarios that feature:

  • More than a dozen hands-on labs to understand PLC operations and interpret ladder diagrams
  • 12 practice exercises and guided faults on a basic PLC controlled circuit for troubleshooting practice
  • Three unique PLC troubleshooting scenarios with over 45 challenging malfunctions to diagnose and repair

Typical components found in these simulations are:

  • PLCs with separate control, digital input and digital output modules
  • DC power supplies
  • A variety of input components
  • Relays and other output components

In these simulations practice:

  • Performing voltage, resistance, and other tests with the multimeter
  • Tracing and disconnecting wires and replace components
  • Operating inputs in the circuit
  • Connecting a virtual laptop to the PLC where you will be able to:
    • Go online and change modes
    • Monitor the operation of the ladder diagram
    • Change settings in the ladder diagram
    • Download programs to the PLC
