Technical data
LED "Status/Error"
LED "Status/Error" is a green and red dual LED. The LED states have a different meaning depending on the
operating mode.
Ethernet mode
In this mode, the interface is operated as an Ethernet interface.
Green - Status
On
POWERLINK
Red - Error
On
Green - Status
Off
NOT_ACTIVE
Flickering green (approx. 10 Hz)
BASIC_ETHERNET
Single flash (approx. 1 Hz)
PRE_OPERATIONAL_1

Description
The interface is being operated as an Ethernet interface.
Table 183: LED "Status/Error" - Ethernet mode
Description
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
Status
Green
Error
Red
LED "S/E"
Table 184: LED "Status/Error" - POWERLINK - Error
Description
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 a frame is not received within the configured time window (time-
out), the interface immediately enters mode PRE_OPERATIONAL_1 (single flash). If POWERLINK communica-
tion is detected before the time expires, however, then the MN is not started.
Controlled node (CN)
The bus is monitored for POWERLINK frames. If a corresponding frame is not received within the configured
time frame (timeout), then the module immediately enters mode BASIC_ETHERNET (flickering). If POWERLINK
communication is detected before this time expires, however, the interface immediately enters mode PRE_OP-
ERATIONAL_1 (single flash).
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).
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)
The module can be configured by the MN in this state. The CN waits until it receives an SoC frame and then
switches to state PRE_OPERATIONAL_2 (double flash). A solid red LED in this state indicates failure of the MN.
