NOT_ACTIVE
Managing node (MN)
The bus is monitored for POWERLINK frames. If a frame is not received within the configured time window
(timeout), the interface goes directly into the PRE_OPERATIONAL_1 state (single flash).
If POWERLINK communication is detected before this time passes, however, the interface goes directly into the
BASIC_ETHERNET state (flickering).
Controlled node (CN)
The bus is monitored for POWERLINK frames. If a frame is not received within the configured time window
(timeout), the interface goes directly into the BASIC_ETHERNET state (flickering).
If POWERLINK communication is detected before this time passes, however, the interface goes directly into the
PRE_OPERATIONAL_1 state (single flash).
Green flickering (approx. 10 Hz)
BASIC_ETHERNET
The interface is in the BASIC_ETHERNET state and being operated purely as an Ethernet TCP/IP interface.
Managing node (MN)
This state can only be changed by resetting the interface.
Controlled node (CN)
If POWERLINK communication is detected while in this state, the interface goes into the PRE_OPERATIONAL_1
state (single flash).
Single flash (approx. 1 Hz)
PRE_OPERATIONAL_1
The interface status is in the PRE_OPERATIONAL_1 state.
Managing node (MN)
The MN starts "reduced cycle" operation. Collisions are allowed on the bus. Cyclic communication is not yet
taking place.
Controlled node (CN)
The CN waits until it receives an SoC frame and then goes into the PRE_OPERATIONAL_2 state (double flash).
Double flash (approx. 1 Hz)
PRE_OPERATIONAL_2
The interface status is in the PRE_OPERATIONAL_2 state.
Managing node (MN)
The MN begins cyclic communication (cyclic input data is not yet evaluated). The CNs are configured in this state.
Controlled node (CN)
In this state, the interface is normally being configured by the manager. Once complete, a command changes
the state to PRE_OPERATIONAL_3 (triple flash).
Triple flash (approx. 1 Hz)
READY_TO_OPERATE
The interface status is in the READY_TO_OPERATE state.
Managing node (MN)
Normal cyclic and asynchronous communication. Received PDO data is ignored.
Controlled node (CN)
The configuration of the interface is complete. Normal cyclic and asynchronous communication.
The PDO data sent corresponds to the PDO mapping. Cyclic data is not yet evaluated, however.
On
OPERATIONAL
The interface status is in the OPERATIONAL state.
Blinking (approx. 2.5 Hz)
STOPPED
The interface status is in the STOPPED state.
Managing node (MN)
This status is not possible for the MN.
Controlled node (CN)
No output data is produced, and no input data is received. It is only possible to enter or leave this state after the
manager has given the appropriate command.

System failure error codes
Incorrect configuration or defective hardware can cause a system failure error.
The error code is indicated by the red error LED using four switch-on phases. The switch-on phases have a duration
of either 150 ms or 600 ms. Error code output is repeated cyclically after 2 seconds.
