Programmable Logic Controllers: Troubleshooting Hardware

The human-machine interface, or HMI, can be a very helpful aid to troubleshooting programming logic controller (PLC) hardware. By itself, however, the HMI cannot always provide information needed to troubleshoot a complex PLC system. Other aids must be used to help in hardware troubleshooting. This course will examine how to use the PLC itself, the HMI, and other test equipment to troubleshoot PLC hardware.
