Description
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
Status
Green
Error
Red
S/E LED
Note: The LED blinks red several times immediately after startup. This is not an error.
Description
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 frame is not received within the configured time window
(timeout), the module goes directly into 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 monitored for POWERLINK frames. If a corresponding frame is not received within the defined time
frame (timeout), then the module will directly enter BASIC_ETHERNET mode (flickering). If POWERLINK com-
munication is detected before this time passes, however, the module goes directly into PRE_OPERATIONAL_1
mode (single flash).
Mode
The module is in BASIC_ETHERNET mode. The interface is 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 goes into the PRE_OPERATIONAL_1
state (single flash).
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 goes
into the PRE_OPERATIONAL_2 state (double flash).
An LED lit red in this state indicates a failure of the MN.
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. After this, a command changes the state to
READY_TO_OPERATE (triple flash).
An LED lit red in this mode indicates a failure of the MN.
