3.1.2 Signal status LEDs
This manual only describes the LED signal statuses of the PROFINET IO modules. Information for the
frequency inverter LEDs (SK 200E) can be found in the relevant manual (BU0200).
The statuses indicated by the LED can be read out with the aid of a parameterisation tool from Getriebebau
Nord (NORDCON software ParameterBox) and also of course via the information parameter (P173) “Module
Status” (See Section 6.2.3 "BUS module information parameters, general (P17x)").
3.1.2.1 Module-specific displays
The status of the technology unit or the system bus is indicated by the LEDs DS and DE.
DS
(Device State)
Green LED
DE
(Device Error)
Red LED
Meaning
long flashing = 0.5 s on / 1 s off
short flashing = 0.25 s on / 1 s off
OFF OFF Technology unit not ready, no control voltage
ON OFF Technology unit ready, no error, at least one frequency inverter is
communicating via the system bus
ON Short flashing Technology unit ready, however
 one or more of the connected frequency inverters has a fault status
(see frequency inverter manual)
Long flashing OFF Technology unit ready and at least one further subscriber is connected
to the system bus, but
 No frequency inverter on the system bus (or connection interrupted)
 Address error for one or more system bus participants
Long flashing Short flashing
Flash interval
1 x - 1s pause
System bus is in status "Bus Warning"
 Communication on system bus interrupted or
 no other participant present on the system bus
Long flashing Short flashing
Flash interval
2 x - 1s pause
 System bus is in status "Bus off" or
 the system bus 24V power supply was interrupted during operation
Long flashing Short flashing
Flash interval
3 x - 1s pause
No system bus 24V power supply
(system bus is in status "Bus off")
Long flashing Short flashing
Flash interval
4 x - 1s pause
 PROFINET error of the technology unit
Details: LED flashing code: RUN and BF
(Section 3.1.2.2 "PROFINET displays"
OFF Short flashing
Flash interval
1…7 x - 1s pause
System error, internal program sequence interrupted
 EMC interference (observe wiring guidelines!)
 Module faulty
