ENETPWR/RDYLEDSignaling
ThistopicdescribeshowtointerpretthePWR/RDYLEDerrorcodes.
ThePWR/RDYLEDhasseveralpurposesontheserialENETs.When
youfirstpowerontheunit,thePWR/RDYLEDalternatesrapidly
betweenredandyellowwhileitcompletesitspower-onself-testsand
acquiresnetworkparameters.Whenthetestscompletesuccessfullyand
theIPaddressisassignedfromeithernonvolatilememoryorthe
network,thePWR/RDYLEDremainssteadyyellow,indicatingthatthe
unitisreadytooperate.
ThePWR/RDYLEDalsoalternatesrapidlybetweenredandyellowwhile
thedeviceisinnetworkconfigurationmode.Atothertimes,the
PWR/RDYLEDblinksslowlyinarecognizablepatterntoalertyouof
internalerrors.Usethefollowingstepstointerpretandrecordthepattern
thatthePWR/RDYLEDflashes,andthencontactNationalInstruments.
NoteByrecordingthePWR/RDYLEDerrormessagesbefore
callingNationalInstruments,youcansaveyourselftime,and
customersupportcanansweryourquestionsmoreaccuratelyand
efficiently.DonotswitchoffpowertoyourserialENETbefore
recordingtheflashingPWR/RDYLEDpattern.
PWR/RDYLEDsignalingcanreportupto81differenterrors.Theerrors
arenumberedfrom11to99andarereportedthroughsequencesof
PWR/RDYLEDflashes.
NoteThereisnozeroinanyerrormessage.Thismeansthat
errormessagenumbers0–10,20,30,40,50,60,70,80,and90
arenotpossible.
