Description
Interface being operated as an Ethernet interface
Table 133: Status/Error LED - Ethernet mode
Description
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
Status
Green
Error
Red
LED "S/E"
Table 134: Status/Error LED - POWERLINK - Error
Description
State
The interface is in state NOT_ACTIVE 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 mode BASIC_ETHERNET (flickering). If POW-
ERLINK communication is detected before this time expires, however, the interface switches immediately to
PRE_OPERATIONAL_1 mode (single flash).
State
The interface is in state BASIC_ETHERNET 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_OPERATION-
AL_1 state (single flash).
State
The interface is in state PRE_OPERATIONAL_1.
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 state PRE_OPERATIONAL_2 (double flash). An LED lit red in this state indicates failure of the MN.
