9.2.3

LED "(Bus) State"

Lights green
Flashes green
Flashes green/red
Lights red
9.2.4

LED "Power"

This LED is connected directly to the (optionally also electrically isolated) supply voltage of the
serial interface (RS232/422/485).
Note: With the Option I/O8 the LED can take more states (see also chapter 8.4).
9.2.5

LED "State"

Lights green
Flashes green
Flashes green/red
Lights red
Flashes red
9.2.6

LEDs 1 / 2 / 4 / 8 (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 han-
dling".
9.2.7

Switches

The Gateway features 5 switches with the following functions:
Rotary coding switch S4
Rotary coding switch S5

Termination (Profibus)

Rotary coding switch High
Rotary coding switch Low
9.2.7.1

Rotary coding switches S4 + S5 (serial interface)

This value is read in when the gateway is switched on.
9.2.7.2 Termination (PROFIBUS)
If the Gateway is operated as the first or last physical device in the PROFIBUS DP, there must be
a bus termination at this Gateway. In order to do this, either a bus terminating resistor must be
activated in the connector or the resistor (220 ) integrated in the Gateway must be activated. In
order to do this, slide the slide switch to position ON. In all other cases, the slide switch must
remain in position OFF. Please refer to the general PROFIBUS literature for further information
on the subject of bus termination.
Note: To activate or deactivate the bus termination, please remove the bus-connector and care-
fully set the switch to the desired position.
28.9.20 Fieldbus-Gateway UNIGATE
PROFIBUS in the state data exchange
Gateway waits for PROFIBUS communication data
Gateway waits for PROFIBUS parameter data
General PROFIBUS error
Data exchange active; controllable via Script
Connection ok but no constant data exchange; controllable via Script
No data exchange since switching on; controllable via Script
General Gateway error (see LEDs Error No.); controllable via Script
UNIGATE is in the configuration / test mode; controllable via Script
ID High for serial interface i. e. configmode
