12.3.3 LED "Link / Activity 2"
This LED is directly controlled by the Powerlink processor and shines when the Gateway is loca-
ted at the RJ45 (2) at a working net (link pulses are received) and flickers during network data
traffic (Activity).
12.3.4 LED "State / Error"
12.3.5 LED "Power"
This LED is connected directly to the (optionally also electrically isolated) supply voltage of the
serial interface (RS232/422/485).
12.3.6 LED "State"
12.3.7 LEDs (Error No. / Select ID)
If these 4 LEDs flash and LED “State“ simultaneously lights red, the error number is displayed in
binary notation (conversion table, see Annex) in accordance with the table in chapter "Error
handling". Additionally these LEDs are controllable via Script:
12.4 Switches
The Gateway features 6 switches with the following functions:
Termination Rx 422 switchable Rx 422-terminating resistor for the serial interface
Termination Tx 422 switchable Tx 422- or RS485-terminating resistor for the serial
interface
Rotary coding switch S4 ID High for serial interface i. e. configmode
Rotary coding switch S5 ID Low for serial interface i. e. configmode
Rotary coding switch High Powerlink Node ID (High byte)
Rotary coding switch Low Powerlink Node ID (Low byte)
12.4.1 Termination Rx 422 + Tx 422 (serial interface)
If the Gateway is operated as the physically first or last device in an RS485-bus or as 422, there
must be a bus termination at this Gateway. In order to do this the termination switch is set to posi-
tion ON. The resistor (150
Ω
) integrated in the Gateway is activated. In all other cases, the switch
remains in position OFF.
Please refer to the general RS485 literature for further information on the subject of bus termina-
tions.
