1.7.3 Displaying and Setting the PROFIBUS Address
Interpreting the PROFIBUS Address Display
If the top LED (“ADR”) of the group display is lit up red, the 7
lower LEDs indicate the PROFIBUS address of the
DP/AS-i Link 20E in binary format.
Setting the PROFIBUS Address
To set the PROFIBUS address of the DP/AS-i Link 20E module, follow the steps
outlined below:
1. Interrupt the connection to the DP master (for example by unplugging the
PROFIBUS connector) or switch the DP master to STOP.
Note
The PROFIBUS address can only be set in this mode.
2. Change the display on the DP/AS-i Link 20E module until the “ADR” LED is lit
red by pressing the DISPLAY button (note: starting from the status display, the
button must be pressed 15 times!).
The DP/AS-i Link 20E module then indicates the currently set PROFIBUS
address using the 7 lower LEDs.
3. If you now press the DISPLAY button, the DP/AS-i Link 20E returns to the
status display, the set PROFIBUS address is retained.
If, on the other hand, you press the SET button, you can set a new value for the
PROFIBUS address. First of all, the “BF” LED flashes and the most significant
bit of the PROFIBUS address is displayed.
4. If you press SET, this bit is set (LED on), if you press the DISPLAY button, the
bit is reset (LED off). The display then jumps to the “SF” LED (next address bit
of the PROFIBUS address).
5. By following the steps outlined above, you can now set or reset each of the
individual bits of the PROFIBUS address.
