1.3.7.1.3 State LEDs
The PROFIBUS state is shown by state LEDs.
Table 30: Meaning of the diagnosis LEDs
LED Color State Description
PWR Green ON (light) Power supply available.
OFF (dark) Power supply not available or defective
hardware
RDY Yellow ON Boot procedure
Blinking Boot failure
OFF ---
RUN Green ON Communication module is operational
Blinking ---
OFF Communication module is not operational
STA Green ON Communication to all slaves is established
Flashes cyclic ---
Flashes non-
cyclic
No configuration or stack error
OFF No communication
ERR Red Blinking No data exchange to the master module
or the cable is disconnected
OFF No error
STA Yellow Blinking
(synchronously)
No production data available,
no bus communication possible.
ERR Yellow
LED state
during
firmware
update
STA Green Blinking
(synchronously)
Firmware file transfers during
communication module firmware update.
ERR Red
STA Green Blinking
(alternately)
Communication module writes the
firmware file to the internal flash.
Do not power off the PLC!
ERR Red
