Setting the PROFIBUS Address 

 

The measuring amplifier requires a unique 
PROFIBUS address which distinguish the 
device definitely in the whole PROFIBUS 
network. No other PROFIBUS device in the 
same network may use the same address. 
The address has to be between 0...125. 
 
The PROFIBUS address is set with the DIP 
switch (fig. 9). Please refer to the table 
below for the setting. After switching the 
measuring amplifier off and on, the new 
address becomes valid.
