Commissioning, fault scenarios and final exam
Цель: Изучить тему «Commissioning, fault scenarios and final exam» и закрепить её практическими заданиями и самопроверкой.
2 акад. часа чтение и разбор теории, решение задач, работа со схемой или виртуальным стендом и проверка понимания.
Commissioning sequence
Documentation review.
Mechanical completion.
Instrument calibration.
Loop checks.
I/O and PLC logic test.
Interlock test.
HMI/alarm test.
Dry simulation.
Controlled process startup.
PID tuning.
Performance test.
Handover/as-built.
Fault scenarios for final assessment
Student receives randomly selected faults:
pressure AI scaling wrong;
Pt100 wire open;
radar false echo;
magmeter empty pipe;
valve stiction;
Modbus timeout;
PLC permissive missing;
PID reverse action;
HMI stale tag;
HH switch bypass left active.
For each, student must identify symptom, likely layer, diagnostic steps, safe actions and documentation.
Final evaluation
Recommended scoring:
| Section | Weight |
|---|---|
| Theory test | 20 % |
| P&ID and instrument selection | 20 % |
| PLC/sequence | 20 % |
| Control/PID | 15 % |
| HMI/alarm design | 10 % |
| Commissioning/troubleshooting | 15 % |
Passing threshold may be set by training organization according to its educational requirements.
Что нужно запомнить
