Deutschmann Automation GmbH & Co. KG
Hardware ports, switches and LEDs
11.5.1
LED “Bus Error“
This LED is activated directly by the Profibus ASIC and signals that the Profibus is not in “DATA
EXCHANGE” status.
11.5.2
LED “Bus Power“
This LED is connected directly to the electrically isolated supply voltage of the Profibus end.
11.5.3
LED “Bus State“
11.5.4
LED “Power“
This LED is connected directly to the (optionally also electrically isolated) supply voltage of the
RS485/RS232 end.
11.5.5
LED “State“
11.5.6
LEDs “Error No. / Select ID“ at UNIGATE RS
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". Otherwise, the address with which communication is currently running via the RS485
interface is displayed, also in binary notation.
11.6 Switches
The gateway features 7 switches with the following functions:
Rotary coding switch, Profibus High
ProfibusDP ID (High Byte)
Rotary coding switch, Profibus Low
ProfibusDP ID (Low Byte)
Slide switch “Termination“
Switchable ProfibusDP terminating resistor
Rotary coding switch S4
RS485 ID (High Byte)
Rotary coding switch S5
RS485 ID (Low Byte)
Slide switch “Interface“
Selector switch for RS485 or RS232 interface
Slide switch “Termination“
Switchable RS485 terminating resistor
11.6.1
Rotary coding switch (Profibus ID)
These two switches are used to set the Profibus ID (00..7D) of the gateway in hexadecimal nota-
tion. A conversion table from decimal to hexadecimal can be found in the Annex. This value is
read in only once when the gateway in activated.
