Commissioning the PROFIBUS interface
!
Note!
• All functions required for commissioning are described in detail in the "Description of
Device Functions" manual which is a separate part of this Operating Manual.
• A code (factory setting: 65) must be entered to change device functions, numerical values
or factory settings
7.4.1
PROFIBUS DP/PA commissioning
The following steps must be carried out in the sequence specified:
1.
Check the hardware write protection:
The WRITE PROTECT parameter indicates whether it is possible to write to the device
parameters via PROFIBUS (acyclic data transmission, e.g. via operating program "Field-
Care").
!
Note!
This check is not needed if operating via the local display.
COMMUNICATION
WRITE PROTECT
Display of one of the following options:
– OFF (factory setting) = write access via PROFIBUS possible
– ON = write access via PROFIBUS not possible
Deactivate the write protection if necessary.

2.
Enter the tag name (optional):

3.
Configuring the fieldbus address:
‣
Software addressing using the local display or operating program:
COMMUNICATION
FIELDBUS ADDRESS
‣
Hardware addressing via miniature switches

4.
Select the system unit:
a. Determine the units by means of the "System units" group: SYSTEM UNITS
UNIT
MASS FLOW / UNIT CORR. VOLUME FLOW/ UNIT…
b. In the function UNIT TO BUS, select the option SET UNITS so that the measured vari-
ables transmitted cyclically to the PROFIBUS Master (class 1) are transmitted with
the system units set in the measuring device:
COMMUNICATION
UNIT TO BUS
!
Note!
– The configuration of the system units for the totalizer is described in step 6.
– If the system unit of a measured variable is changed by means of the local operation
or an operating program, this initially does not have any effect on the unit that is used
to transmit the measured variable to the PROFIBUS Master (class 1). Changed system
units of the measured variables are not transmitted to the PROFIBUS Master (class 1)
until the SET UNITS option is activated in the function COMMUNICATION
UNIT TO
BUS.
