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:

 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.
