Fieldbus Coupler 750-341 ï 81LED DisplayWAGO-I/O-SYSTEM 750ETHERNET TCP/IP3.1.7.2 Fieldbus statusThe health of the ETHERNET Fieldbus is signalled through the top LEDgroup (ëLINKë, ëMSë, ëNSë and ëTxD/RxDë). The two-colored LEDs ëMSí(module status) and ëNSí (network status) are solely used by the Ethernet/IPprotocol. These two LEDs conform to the Ethernet/IP specifications.LED Meaning Trouble shootingLINKgreen Link to a physical network existsOFF No link to a physical network Check the fieldbus connection.MSred / greenflashingSelf testred The system indicates a not remediable errorred flashing The system indicates a remediable errorgreenflashingThe system is not yet configuresgreen Normal operationOFF No system supply voltage Check the supply voltage (24V and 0V)NSred / greenflashingSelf testred The system indicates a double IP-address in thenetworkred flashing At least one connection announced a Timeout,where the coupler functions as target.greenflashingNo connectiongreen At least one connection is developed (alsoconnection to the Message rout applies)OFF Dem System ist keine IP-Adresse zugeordnetoder es liegt keine Betriebsspannung anTxD/RxDgreen Data exchange via ETHERNET taking placeOFF No data exchange via ETHERNET3.1.7.3 Node statusThe ëI/Oë-LED displays the communication status of the internal bus.Additionally, this LED is used to display fault codes (blink codes) in the eventof a system error.LED Meaning Trouble shootingI/OGreen Fieldbus coupler operating perfectlyRed a) During startup of fieldbus coupler:Internal bus being initialized,Startup displayed by LED flashing fast for approx.1-2 secondsRed b) After startup of fieldbus coupler:Errors, which occur, are indicated by three conse-cutive flashing sequences.
