LED "S/E"
Green Red Description
Single flash Off Mode: PRE_OPERATIONAL_1
(approx. 1 Hz) The interface is in mode PRE_OPERATIONAL_1.
Managing node (MN)
The MN is in "reduced cycle" mode. 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.
Triple flash Off Mode: READY_TO_OPERATE
(approx. 1 Hz) The interface is in mode READY_TO_OPERATE.
Managing node (MN)
Cyclic and asynchronous communication. Received PDO data is ignored.
Controlled node (CN)
The configuration of the CN is completed. Normal cyclic and asynchronous communication. The transmitted PDO data corre-
sponds to the PDO mapping. However, cyclic data is not yet evaluated.
On Controlled node (CN)
If the red LED lights up in this mode, this means that the MN has failed.
On Off Mode: OPERATIONAL
The interface is in mode OPERATIONAL. PDO mapping is active and cyclic data is evaluated.
Blinking Off Mode: STOPPED
(approx. The interface is in mode STOPPED.
2.5 Hz)
Managing node (MN)
This mode does not occur for the MN.
Controlled node (CN)
Output data is not being output, and no input data is being provided. This mode can only be reached and exited by a corre-
sponding command from the MN.
