4.12.3.6.1.3 POWERLINK V2
Red - Error
Description
On
The module is in an error mode (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:
•
PRE_OPERATIONAL_1
•
PRE_OPERATIONAL_2
•
READY_TO_OPERATE

"S/E" LED
Status
Green
Error
Red
Note:
The LED blinks red several times immediately after startup. This is not an error.

Green - Status
Description
Off
Mode
The module is in NOT_ACTIVE mode or:
•
Switched off
•
Starting up
•
Not configured correctly in Automation Studio
•
Defective
Managing node (MN)
The bus is monitored for POWERLINK frames. If a corresponding frame is not received within the defined time frame
(timeout), then the module will immediately enter PRE_OPERATIONAL_1 mode.
If POWERLINK communication is detected before the time expires, however, then the MN will not be started.
Controlled node (CN)
The bus is monitored for POWERLINK frames. If a corresponding frame is not received within the defined time frame
(timeout), then the module will immediately enter BASIC_ETHERNET mode. If POWERLINK communication is detected
before this time passes, however, then the module will immediately go into PRE_OPERATIONAL_1 mode.
Green flickering (approx. 10 Hz)
Mode
The module is in BASIC_ETHERNET mode. The interface is being operated as an Ethernet TCP/IP interface.
Managing node (MN)
This state can only be changed by resetting the module.
Controlled node (CN)
If POWERLINK communication is detected while in this state, the module will transition to the PRE_OPERATIONAL_1
state.
Single flash (approx. 1 Hz)
Mode
The module 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 transitions
to the PRE_OPERATIONAL_2 state.
An LED lit red in this state indicates a failure of the MN.
Double flash (approx. 1 Hz)
Mode
The module is in PRE_OPERATIONAL_2 mode.
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)
The module can be configured by the MN in this state. A command then changes the state to READY_TO_OPERATE.
An LED lit red in this mode indicates a failure of the MN.
Triple flash (approx. 1 Hz)
Mode
The module is in the READY_TO_OPERATE state.
Managing node (MN)
Cyclic and asynchronous communication. The received PDO data is ignored.
Controlled node (CN)
The module configuration is complete. Normal cyclic and asynchronous communication. The PDO data sent corresponds
to the PDO mapping. Cyclic data is not yet evaluated, however.
An LED lit red in this mode indicates a failure of the MN.
