Lesson 4: PLC, I/O, Program, Hardware, and Communication Diagnostics
Lesson Overview
This lesson develops practical skills in plc, i/o, program, hardware, and communication diagnostics for the TIA Portal Advanced Siemens PLC Programming Training course, with implementation, verification, documentation, and troubleshooting guidance.
Topics Covered
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
Practical Activity
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.
Key Takeaways
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.
