Status/Error LED
The Status/Error LED is a green and red dual LED. The LED status can have different meanings depending on
the operating mode.
Ethernet mode
In this mode, the interface is operated as an Ethernet interface.
Green - Status
Description
On
Interface being operated as an Ethernet interface
Table 63: Status/Error LED - Ethernet mode
POWERLINK
Red - Error
Description
On
The interface is in an error state (failed Ethernet frames, increased number of collisions on the network, etc.).
If an error occurs in the following states, then the green LED blinks over the red LED:
•
BASIC_ETHERNET
•
PRE_OPERATIONAL_1
•
PRE_OPERATIONAL_2
•
READY_TO_OPERATE

NOT_ACTIVE
Mode
The interface is in NOT_ACTIVE mode or:
•
Switched off
•
Starting up
•
Not configured correctly in Automation Studio
•
Defective
Managing node (MN)
The bus is being monitored for POWERLINK frames. If a frame is not received within the configured time window
(timeout), the interface switches immediately to PRE_OPERATIONAL_1 mode (single flash). If POWERLINK
communication is detected before the time expires, however, then the MN will not be started.
Controlled node (CN)
The bus is being monitored for POWERLINK frames. If a corresponding frame is not received within the defined
time frame (timeout), then the module switches immediately to BASIC_ETHERNET mode (flickering). If POW-
ERLINK communication is detected before this time expires, however, the interface switches immediately to
PRE_OPERATIONAL_1 mode (single flash).
