5.1.1.2 POWERLINK V2 mode
Error message
LED "S/E"
Green
Red
Description
Off
On
The interface is in the 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:

Description
Mode: NOT_ACTIVE
Off
Off
The interface is either in mode NOT_ACTIVE or one of the following modes or errors is present:
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.
Flickering
Off
Mode: BASIC_ETHERNET
(approx.
The interface is in mode BASIC_ETHERNET. The interface is operated in
10 Hz)
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.
Mode: PRE_OPERATIONAL_1
Single flash
Off
(approx. 1 Hz)
The interface is in mode PRE_OPERATIONAL_1.
Managing node (MN)
The MN is in "reduced cycle" operation. The CNs are configured in this mode.
Cyclic communication is not yet taking place.
Controlled node (CN)
The CN can be configured by the MN in this mode. The CN waits until it receives an SoC frame and then switches to mode
PRE_OPERATIONAL_2.
On
Controlled node (CN)
If the red LED lights up in this mode, this means that the MN has failed.
Double flash
Off
Mode: PRE_OPERATIONAL_2
(approx. 1 Hz)
The interface is in mode PRE_OPERATIONAL_2.
Managing node (MN)
The MN starts cyclic communication (cyclic input data is not yet evaluated).
The CNs are configured in this mode.
Controlled node (CN)
The CN can be configured by the MN in this mode. A command then switches the mode to READY_TO_OPERATE.
On
Controlled node (CN)
If the red LED lights up in this mode, this means that the MN has failed.
