Symptom / LED pattern	Likely Cause (what it means)	Recommended Corrective Action
PWR LED off (no green)	24 V DC not present or too low	Verify cabinet supply is 24 V DC (-15 %/+20 %), check terminals and fuse, then repower unit.
PWR LED flashes red (8 Hz)	Power-controller fault on the IPC	Remove 24 V, wait ≥ 10 s, inspect wiring for shorts; if repeat fault, replace CX power-supply module.
TC LED red / yellow	TwinCAT in Stop or PLC crash	Open TwinCAT on engineering PC, read error list, correct PLC code or fieldbus mapping, then switch state back to Run.
HDD LED permanently red after boot	CFast / micro-SD not detected or corrupt	Re-seat/remap CFast card, check file-system integrity; replace card if LED stays red.
FB1 / FB2 LED red	Fieldbus (e.g., EtherCAT, Profibus) offline	Verify bus cable, topology and address; repair broken segment; restart fieldbus master, then reset faults.
K-bus ERR LED red/blinking	I/O terminal fault or address conflict	Count blink code, check offending terminal; reseat or replace terminal, then reset controller.
Device shuts down or throttles, housing > 70 °C	CPU over-temperature	Improve cabinet airflow, lower ambient to ≤ 60 °C, clean filters; confirm device temperature falls before restart.
System clock resets on power-up	CMOS coin-cell battery depleted	Replace 3 V lithium cell (front flap), set correct date/time in BIOS; export PLC certificates after battery change.
1-second UPS warning in TwinCAT log	Super-capacitor UPS at end of life	Run 24-h recharge; if capacity < 1 MB, order Beckhoff cap-pack repair kit and rebuild UPS module.
Both Ethernet port link LEDs dark	Cable, switch or NIC disabled in BIOS	Test with known-good patch cable; enable NICs in BIOS; reload driver in Windows/TwinCAT/BSD.

Blink Pattern / Code	Meaning
Persistent rapid flashing	Electromagnetic-interference (EMC) disturbance or unstable 24 V supply
3 pulses – arg 0	K-bus command error (no Bus Terminal or defective terminal present)
4 pulses – arg 0	K-bus data error – break detected directly after the power-supply terminal
4 pulses – arg n	Break behind Bus Terminal n (wiring/open-circuit at that position)
5 pulses – arg n	Register-communication error with Bus Terminal n (terminal hardware fault)
6 pulses – arg 0	Error during controller initialisation (replace or reflash Embedded PC)
6 pulses – arg 1	Internal data error – recover by power-cycling the CX5140
6 pulses – arg 8	Internal data error – hardware reset required (cycle 24 V)
7 pulses – arg 0	Mismatch between configured and actual K-bus process-image lengths
TC LED yellow	PLC crash / TwinCAT runtime exception detected (controller has halted)
