ثامنا. Common Fault Troubleshooting Matrix

أعراض الخطأ	السبب الجذري	Resolution Steps
Steady red ERR LED on module	Faulty backplane bus communication / poor baseplate contact	1. Re-seat the module; 2. Verify termination covers at both ends of X20 bus; 3. Restart CPU
Channel LED remains off despite sensor output	1. الأسلاك فضفاضة; 2. Reversed input polarity; 3. Missing sensor power supply	Check 24V power supply, NPN/PNP wiring logic, and fasten spring terminals
Frequent false signal triggering	Insufficient debounce filter time, cable electromagnetic interference	Increase input filter duration to 5–10 ms in Automation Studio; apply shielding and grounding to signal cables
Complete signal loss for a full group of 8 القنوات	Broken isolated power supply for the group, disconnected common COM terminal wiring	Inspect 24V wiring for each group’s common COM terminal
