POWERLINK
Red - Error
Description
On
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

Green - Status
Description
Off
NOT_ACTIVE
Mode
The interface is in NOT_ACTIVE mode or:
•
Switched off
•
Starting up
•
Not configured correctly in Automation Studio
•
Defective
Managing node (MN)
The bus is being monitored for POWERLINK frames. If a frame is not received within the configured time window
(timeout), the interface switches immediately to PRE_OPERATIONAL_1 mode (single flash). If POWERLINK
communication is detected before the time expires, however, then the MN will not be started.
Controlled node (CN)
The bus is being monitored for POWERLINK frames. If a corresponding frame is not received within the defined
time frame (timeout), then the module switches immediately to BASIC_ETHERNET mode (flickering). If POW-
ERLINK communication is detected before this time expires, however, the interface switches immediately to
PRE_OPERATIONAL_1 mode (single flash).
Green flickering (approx. 10 Hz)
BASIC_ETHERNET
Mode
The interface is in BASIC_ETHERNET mode and being 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 while in this state, the interface switches to the
PRE_OPERATIONAL_1 state (single flash).
Single flash (approx. 1 Hz)
PRE_OPERATIONAL_1
Mode
The interface is in PRE_OPERATIONAL_1 mode.
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 the PRE_OPERATIONAL_2 state (double flash). An LED lit red in this state indicates failure of the MN.
Double flash (approx. 1 Hz)
PRE_OPERATIONAL_2
Mode
The interface is in the PRE_OPERATIONAL_2 state.
Managing node (MN)
The MN begins cyclic communication (cyclic input data is not yet being evaluated). The CNs are configured in
this state.
Controlled node (CN)
The interface can be configured by the MN in this state. A command then switches the state to
READY_TO_OPERATE (triple flash). An LED lit red in this mode indicates failure of the MN.
Triple flash (approx. 1 Hz)
READY_TO_OPERATE
Mode
The interface is in the READY_TO_OPERATE state.
Managing node (MN)
Cyclic and asynchronous communication is taking place. Any received PDO data is ignored.
Controlled node (CN)
The configuration of the module is completed. Normal cyclic and asynchronous communication is taking place.
The PDO data being sent corresponds to the PDO mapping. Cyclic data is not yet being evaluated, however. An
LED lit red in this mode indicates failure of the MN.
On
OPERATIONAL
Mode
The interface is in OPERATIONAL mode. PDO mapping is active and cyclic data is being evaluated.
