Proline Promag 55 PROFIBUS DP/PA Commissioning
Endress+Hauser 91
• Using the CHANNEL function (6133), you can determine the measured variable (e.g. Mass
Flow) to be cyclically transmitted to the PROFIBUS master (Class 1) as a totalizer value:
a. Select BASIC FUNCTION (G) PROFIBUS PA (GCA) TOTALIZER (613)
SELECT TOTALIZER (6130).
b. Select the option TOTALIZER 1.
c. Go to the function CHANNEL (6133).
d. Select the option MASS FLOW.
Possible settings See following table
• Enter the desired unit for the totalizer:
BASIC FUNCTION (G) PROFIBUS PA (GCA) TOTALIZER (613)
UNIT TOTALIZER (6134)
• Configure totalizer status (e.g. totalize):
BASIC FUNCTION (G) PROFIBUS PA (GCA) TOTALIZER (613)
SET TOT (6135) Select the option TOTALIZE
• Set the totalizer mode:
BASIC FUNCTION (G) PROFIBUS PA (GCA) TOTALIZER (613)
TOTALIZER MODE (6137) Select one of the following options:
– BALANCE (factory setting): calculates the positive and negative flow components
– POSITIVE: calculates the positive flow components
– NEGATIVE: calculates the negative flow components
– HOLD VALUE: the totalizer remains at the last value
!
Note!
For the calculation of the positive and negative flow components (BALANCE) or the negative
flow components only (NEGATIVE) to be carried out correctly, the selection
BIDIRECTIONAL must be active in the function BASIC FUNCTION (G) SYSTEM
PARAMETER (GLA) CONFIGURATION (660) MEASURING MODE (6601).
Possible settings:
8. Select the operating mode
Select the operating mode (GSD file) which should be used for cyclic communication with the
PROFIBUS master (Class 1).
BASIC FUNCTION (G) PROFIBUS PA (GCA) OPERATION (614)
SELECTION GSD (6140) Select:
– MANUFACT. SPEC. (factory setting) The complete device functionality is available.
– MANUFACT V2.0 The device is used as the replacement for the previous Promag 35 model
(compatibility mode).
– PROFILE-GSD: The device is operated in the PROFIBUS Profile mode.
!
Note!
For PROFIBUS network configuration, make sure that the right device master file (GSD file) of
the measuring device is used for the selected operating mode ä 92.
9. Configuration of cyclic data transmission in the PROFIBUS master
A detailed description of the cyclic data transmission is contained on ä 96.
Totalizer value/measured variable ID for CHANNEL function
VOLUME FLOW (factory setting Totalizers 1 to 3) 273
MASS FLOW 277
OFF 0
!
Note!
If, during PROFIBUS network configuration, the module or the function TOTAL was integrated in slot 2, 3 or
4, the measured variable selected in the CHANNEL function is transmitted cyclically to the PROFIBUS master
(Class 1) for the respective Totalizer 1 to 3 ä 99.
