Address Configuration

Normally, the PROFIBUS participants get permanent addresses in the range of
0 ... 125. For the sensor interface the address is set via the DIP switches 1 to 7 in the
right clamp space. Setting is made as a binary digit.
Address 126 must remain free for address assignment via software commands in or-
der to avoid address conflicts with new devices, which are always supplied with this
address.
As soon as an address has been set in the range 0 ... 125, any trial to modify the
PROFIBUS address by means of a software command, is rejected. In this case, setting
by DIP switches has priority.
Therefore, a new address can only be changed by repeating the procedure described
here.
For the sensor interface the switch position 127 is identical to switch position 126, the-
refore, it is interpreted as address 126.
To accept the set address, the device must be separated from
PROFIBUS PA for a short period of time.
When supplied, address 126 is set at the DIP switches.
The sensor interface allows to assign an address via the bus. Here the address 126
must be set via the DIP switches. This is the case for the switch positions 126 (factory
setup) and 127. Whether and how this software setting can be made is described in
the operating instructions of the configuration or parameterization tool used.
Furthermore has to be noticed:
• As long as no address is set via the software command, address 126 is used.
• If an address has been set via the software command, this address is used also if
the device had been separated from the PROFIBUS PA in the mean time.
• If an address 0 ... 125 is set via the DIP switches, this address has priority and the
software address is cleared.
Subject to reasonable modifications due to technical advances.
