6.3 Commissioning PROFIBUS PA units
For units with PROFIBUS PA, the bus address must be checked or configured prior to start-up.
If no bus address information was supplied by the customer, the unit was shipped with its BUS
address set to “126”.
The address must be reset during start-up to a number within the valid range (0 … 125).
Important (Notice)
The address selected may only appear once in the segment.
The address can be set either locally on the unit (via the DIP switches on the digital board),
using system tools, or via a PROFIBUS DP master class 2 such as Asset Vision Basic
(DAT200).
The factory setting for DIP switch 8 is OFF, i.e., the address is set using the fieldbus.
The front cover can be unscrewed to change the settings. It is also possible to set the address
via menu by using the keys on the display board.
The PROFIBUS PA interface conforms with Profile 3.01 (fieldbus standard PROFIBUS, EN
50170, alias DIN 19245 [PRO91]).
The transmitter transmission signal is designed according to IEC 61158-2.
Important (Notice)
The manufacturer-specific PROFIBUS PA ID no. is: 0x3430.
The unit can also be operated with the PROFIBUS standard ID nos. 0x9700 or 0x9740.
