2.3.5.12.3.3 Status/Error LED
The status/error LED is designed as a green and red dual LED. The LED statuses have a different meaning
depending on the operating mode.
Ethernet mode
In this mode, the interface is operated as an Ethernet interface.
Color green - Status
Description
On
The interface is operated as an Ethernet interface.
Table 127: Status/Error LED - Ethernet mode
POWERLINK
Color red - Error
Description
On
The interface is in an error state (failure of Ethernet frames, accumulation of collisions on the network, etc.).
If an error occurs in the following states, the red LED is superimposed by the green flashing LED:
•
BASIC_ETHERNET
•
PRE_OPERATIONAL_1
•
PRE_OPERATIONAL_2
•
READY_TO_OPERATE

Color green - Status
Description
Off
NOT_ACTIVE
State
The interface is in state NOT_ACTIVE or:
•
Switched off
•
Starting up
•
Not configured correctly in Automation Studio
•
Defective
Managing node (MN)
The bus is monitored for POWERLINK frames. If no corresponding frame is received in the set time window
(timeout), the interface immediately enters mode PRE_OPERATIONAL_1 (single flash). If POWERLINK commu-
nication is detected before the time has elapsed, however, the MN is not started.
Controlled node (CN)
The bus is monitored for POWERLINK frames. If no corresponding frame is received in the set time window
(timeout), the module immediately enters mode BASIC_ETHERNET (flickering). If POWERLINK communication
is detected before the time has elapsed, however, the interface immediately enters mode PRE_OPERATIONAL_1
(single flash).
Green flickering (approx. 10 Hz)
BASIC_ETHERNET
State
The interface is in state BASIC_ETHERNET and operated as an Ethernet TCP/IP interface.
Managing node (MN)
This state can only be exited by resetting the interface.
Controlled node (CN)
If POWERLINK communication is detected during this state, the interface enters state PRE_OPERATIONAL_1
(single flash).
Single flash (approx. 1 Hz)
PRE_OPERATIONAL_1
State
The interface is in state PRE_OPERATIONAL_1.
Managing node (MN)
The MN starts "reduced cycle" operation. Cyclic communication is not yet taking place.
Controlled node (CN)
In this state, the module can be configured by the MN. The CN waits for the reception of as SoC frame and then
changes to state PRE_OPERATIONAL_2 (double flash). If the red LED lights up in this state, this means that
the MN has failed.
