A.7 LED "S/E" (LED "Status/Error")
This LED is a green/red dual LED and indicates the state of the POWERLINK interface. The LED states have a
different meaning depending on the operating mode of the POWERLINK interface.
A.7.1 Ethernet mode
In this mode, the interface is operated as an Ethernet interface.

Error message
LED "S/E"
Green
Red
Description
Off
On
The interface is in error mode (failed Ethernet frames, increased number of collisions on the network, etc.).
Note:
Several red blinking signals are displayed immediately after the device is switched on. These are not errors, however.
Blinking
On
If an error occurs in the following modes, then the green LED blinks over the red LED:
•
PRE_OPERATIONAL_1
•
PRE_OPERATIONAL_2
•
READY_TO_OPERATE

Off
Mode:
NOT_ACTIVE
The interface is either in mode NOT_ACTIVE or one of the following modes or errors is present:
•
The device is switched off.
•
The device is in the startup phase.
•
The interface or device is not configured correctly in Automation Studio.
•
The interface or device is defective.
Managing node (MN)
The network is monitored for POWERLINK frames. If a frame is not received within the configured time window (timeout), the
interface immediately enters mode PRE_OPERATIONAL_1.
If POWERLINK communication is detected before the time has elapsed, however, the MN is not started.
Controlled node (CN)
The network is monitored for POWERLINK frames. If a frame is not received within the configured time window (timeout), the
interface immediately enters mode BASIC_ETHERNET. If POWERLINK communication is detected before this time expires,
however, the interface immediately enters mode PRE_OPERATIONAL_1.

Off
Mode:
BASIC_ETHERNET
The interface is in mode BASIC_ETHERNET. The interface is operated in
Managing node (MN)
This mode can only be exited by resetting the controller.
Controlled node (CN)
If POWERLINK communication is detected during this mode, the interface enters mode PRE_OPERATIONAL_1.
