Lesson 4: PLC, I/O, Program, Hardware, and Communication Diagnostics

CPU states, diagnostic buffer, LEDs, module information, alarms, and system diagnostics
Digital and analog I/O faults, wiring, power, grounding, sensors, actuators, and calibration
Program monitoring, watch, trace, cross-reference, forcing precautions, and logic faults
PROFINET names, IP addresses, topology, distributed I/O, module replacement, and communication
Fault isolation, safe correction, evidence collection, validation, and root cause

Create or review a practical configuration for cpu states, diagnostic buffer, leds, module information, alarms, and system diagnostics.
Build and test an exercise involving digital and analog i/o faults, wiring, power, grounding, sensors, actuators, and calibration and program monitoring, watch, trace, cross-reference, forcing precautions, and logic faults.
Use diagnostics or evidence to validate fault isolation, safe correction, evidence collection, validation, and root cause.

Explain cpu states, diagnostic buffer, leds, module information, alarms, and system diagnostics.
Apply digital and analog i/o faults, wiring, power, grounding, sensors, actuators, and calibration and program monitoring, watch, trace, cross-reference, forcing precautions, and logic faults.
Validate and troubleshoot fault isolation, safe correction, evidence collection, validation, and root cause.
