6. When all the bits have been entered, the display of the set address bits
alternates quickly red/green or yellow/green. If you press the SET button again,
the set PROFIBUS address is adopted by the DP/AS-i Link 20E module. If, on
the other hand, you press DISPLAY, the new address is discarded. The entry of
the new address must then be repeated (as in step 4 and 5).
The value of the address bits represented by the LEDs of the PROFIBUS address
is illustrated in the following example:

In the example above, the PROFIBUS address 69 was set with the SET/DISPLAY
buttons.
The highest address that can be set is address 126. Remember that address 126
is reserved on PROFIBUS for special functions (address assignment). For data
exchange with a DP master, you can use addresses 1 to 125.
