Meaning of the RUN/STOP, ERROR and MAINT LEDs

CPU 1518HF-4 PN has three LEDs for displaying the current operating state and diagnostics

status.

Note
LED patterns of the S7-1500H redundant system

Note that it is not always possible to:
•

Determine the state of the CPU from the signal pattern of individual LEDs

•

Determine the state of the other CPU from the signal pattern of a CPU

The "Meaning" column only shows a possible typical cause.
To investigate the cause of the signal pattern, use the diagnostic buffer and its display via:
•

STEP 7

•

HMI devices

•

Displays of the CPUs
