Each hardware component should be tested to verify that it operates properly by itself. Such tests should include

• Alternating current and direct current power checks,

• Power-failure and -restart tests,

• Diagnostics checks, and

• Proof of all specified functions.

In addition, all I/O devices and their components should be tested to verify operability and basic calibration. Where applicable, proper communication among system components should be verified. Communication between each remote I/O and control panel PLC and the master control panel PLC should also be demonstrated.
