7.2.3 ETHERNET LEDs
The ETHERNET LEDs display the overall condition of the E thernet
interface once the startup sequence has completed. The LED codes
conform to the ETHERNET Powerlink Standardization Group (EPSG)
standard at the time of production.
Green( status)
XOff: Node in NO T ACTIVE state. The controlled node is waiting to be triggered by
themanager node.
1flash: Node in PRE-OPERATIONAL1 state. EPL mode is star ting.
2flashes : Nodein PRE-OPERATIONAL2 state. EPL mode is s tarting.
3flashes : Nodein READY TO OPERATE state. The node is signalling its
readiness to operate.
Blinking( continuous flashing): Nodein STOPPED state. The controlled node has
beendeactiv ated.
Flickering(very fast flashing): Node in BASIC ETHERNET s tate(EPL is not
operating,but other E thernet protocols may be used).
Continuously illuminated, not flashing: Nodein OPERATIONAL state. EPL is
operatingnormally.
Red(error)
XOff: EPL is w orking correctly.
Continuously illuminated: A nerror has oc curred.
