Status LED
Status of the Powerlink station
Green
Red
On
Off
The Powerlink station is running with no errors.
Off
On
A fatal system error has occurred. The error type can be read using the PLC logbook. It concerns an
irreparable problem. The system cannot properly carry out its tasks. This status can only be changed
by resetting the module.
Blinking alternately
The Powerlink managing node failed. This error code can only occur in controlled node operation. This
means that the set station number lies within the range $01 - $FD.
Off
Blinking
System failure. The red blinking LED signals an error code (see Section"System halt error codes", on
page 9).

Color red - error
Description
On
The ETHERNET Powerlink interface has encountered an error (failed Ethernet frames, burst of collisions on
the network, etc.).

Green - status
Description
Off
NOT_ACTIVE
Managing Node (MN)
The bus is monitored for ETHERNET Powerlink frames. If no frame is received within the configured time
window (timeout), the interface goes directly into PRE_OPERATIONAL_1 status (single flash).
If, however, ETHERNET Powerlink communication is detected during these 5s, the interface goes directly into
the BASIC_ETHERNET status (flickering).
Controlled Node (CN)
The bus is monitored for ETHERNET Powerlink frames. If no frame is received within the configured time
window (timeout), the interface goes directly into BASIC_ETHERNET status (flickering). If, however,
ETHERNET Powerlink communication is detected during this time, the interface goes directly into the
PRE_OPERATIONAL_1 status (single flash).
Blinking green (approx. 10 Hz)
BASIC_ETHERNET
The interface is in BASIC_ETHERNET status, and is operated as a pure TCP/IP interface.
Managing Node (MN)
This status can only be changed by resetting the interface.
Controlled Node (CN)
If an ETHERNET Powerlink communication is detected while in this status, the interface goes into the
PRE_OPERATIONAL_1 state (single flash).
