Schneider Electric LUFP7 user manual Signalling

3. Signalling

The gateway’s 6 LEDs and the descriptive label on the removable cover which hides its two coding wheels (gateway address) allow you to diagnose the status of the gateway:

		1 ONLINE
	h	2 OFFLINE
g		3 NOT USED
		4 FIELDBUS DIAG

		6 GATEWAY

DEL	LED Æ Gateway state
	Off: Profibus-DP bus:
n ONLINE	Gateway off-line
	Green: Profibus-DP bus:
	Gateway on-line
	(exchanges are possible)
p UNSEDOT	Off: —
	Off: No power
	Flashing (green): No
	Modbus communications
r MODBUS	Green: Modbus
	communications OK
	Red: Loss of communication
	with at least one Modbus
	slave (2)

LED	LED Æ Gateway state
	Off: Profibus-DP bus: gateway on-line
o OFFLINE
	Red: Profibus-DP bus: Gateway off-line
	(exchanges are impossible)
	Off: Gateway initialization achieved
q DFIELDBUSIAG	Flashing red (1 or 2 Hz): Gateway
	configuration error. (1)
	Flashing red (4 Hz): Error when resetting the
	gateway on Profibus-DP. (1)
	Off: No power
	Flashing (red/green): Configuration absent / not valid
s GATEWAY	Use AbcConf to load a valid configuration
	Green: Gateway currently being initialized
	and configured
	Flashing (green): Gateway is in running
	order: Configuration OK

(1) Specific errors indicated by the LED qFIELDBUS DIAG:

•Flashing red LED (1 Hz): input and/or output data length is invalid.

 Check the overall length of the gateway data, under AbcConf (“Monitor” option from the “Sub-Network” menu), then adjust exchanges with the gateway accordingly, using the Profibus-DP network configuration software (e.g.: SyCon).

•Flashing red LED (2 Hz): User parameter data length and/or content is invalid.

•Flashing red LED (4 Hz): Error when resetting the ASIC in charge of Profibus-DP communications.

(2)The LED r MODBUS becomes red whenever you use incorrect values in the outputs corresponding to the queries of the two aperiodic services designed to read/write the value of any parameter of a Modbus slave (see chapter 4.2.10 Description of Services Assigned to Gateway Inputs/Outputs, page 34). This LED will only revert to its former green state if you reuse these very same services, but with correct values. More generally, this LED becomes red, then reverts to a green state, on loss and recovery of the communications with any Modbus slave.

N.B. If the LED s DEVICE STATUS is flashing following a sequence beginning with one or

more red flashes, we advise you to note down the order of this sequence and give this information to the Schneider Electric support service.
