System integration
In conjunction with the DTM (Device Type Manager) to the device,
the communication (configuration, parametrization) can occur with
the corresponding framework applications according to FDT 0.98 or
1.2 (DSV401 R2), respectively. Other desired tool/system inte-
grations (e.g., AMS or Siemens S7) are available upon request.
DSV401 communication tool for HART, free 90-day test version also
available upon request. DTMs are included in DSV401.
4.7.2 PROFIBUS PA protocol
The interface conforms to the Profile 3.0 (Standard PROFIBUS, EN
50170, DIN 19245 [PRO91]).
PROFIBUS PA ID no.: 0849 hex.
Alternative standard ID no.: 9700 or 9742 hex.

Bus topology
• Tree and/or line structure
• Bus termination: passive at both wire ends of the bus main wire
(RC-element R = 100
Ω , C = 1 µF)
Voltage/current consumption
• Medium current consumption: 14 mA.
• In the event of an error, the integrated FDE function (=Fault
Disconnection Electronic) integrated in the device is ensures that
the current consumption can rise to a maximum of 26 mA.
• The upper limit of the voltage is electronically limited.
• The voltage on the bus line must lie in the range of 9 ... 32 V DC.
