Led "S/E" (Led "Status/Error"); Ethernet Mode; Powerlink V2 Mode - B&R Automation PC 3100 User Manual

Appendix A
A.3 LED "S/E" (LED "Status/Error")
This LED is a green/red dual LED and indicates the state of the POWERLINK interface. The LED states have a
different meaning depending on the operating mode of the POWERLINK interface.
A.3.1 Ethernet mode
In this mode, the interface is operated as an Ethernet interface.
LED "S/E"
Green Red Description
On Off The interface is operated as an Ethernet interface.
A.3.2 POWERLINK V2 mode
Error message
LED "S/E"
Green Red Description
Off On The interface is in error mode (failed Ethernet frames, increased number of collisions on the network, etc.).
Note:
Several red blinking signals are displayed immediately after the device is switched on. These are not errors, however.
Blinking On If an error occurs in the following modes, then the green LED blinks over the red LED:
Interface status
LED "S/E"
Green Red Description
Mode: NOT_ACTIVE
Off Off
The interface is either in mode NOT_ACTIVE or one of the following modes or errors is present:
Managing node (MN)
The network is monitored for POWERLINK frames. If a frame is not received within the configured time window (timeout), the
interface immediately enters mode PRE_OPERATIONAL_1.
If POWERLINK communication is detected before the time has elapsed, however, the MN is not started.
Controlled node (CN)
The network is monitored for POWERLINK frames. If a frame is not received within the configured time window (timeout), the
interface immediately enters mode BASIC_ETHERNET. If POWERLINK communication is detected before this time expires,
however, the interface immediately enters mode PRE_OPERATIONAL_1.
Flickering Off Mode: BASIC_ETHERNET
(approx. The interface is in mode BASIC_ETHERNET. The interface is operated in
10 Hz)
Managing node (MN)
This mode can only be exited by resetting the controller.
Controlled node (CN)
If POWERLINK communication is detected during this mode, the interface enters mode PRE_OPERATIONAL_1.
