• Using the CHANNEL function (6133), you can determine the measured variable
(e.g. volume flow) to be cyclically transmitted to the PROFIBUS master (Class 1) as a
totalizer value:
a. Select BASIC FUNCTION (G) PROFIBUS DP (GBA) TOTALIZER (613)
SELECT TOTALIZER (6130).
b. Select the option TOTALIZER 1.
c. Go to the function CHANNEL (6133).
d. Select one of the following options:
– VOLUME FLOW (CHANNEL = 273, factory setting): the volume flow is totalized.
– MASS FLOW (CHANNEL = 277): the mass flow is totalized.
– OFF (CHANNEL = 0): no totalizing, "0"
is displayed as the totalizer value.
!
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.
• Enter the desired unit for the totalizer:
BASIC FUNCTION (G) PROFIBUS DP (GBA) TOTALIZER (613)
UNIT TOTALIZER (6134)
• Configure totalizer status (e.g. totalize):
BASIC FUNCTION (G) PROFIBUS DP (GBA) TOTALIZER (613)
SET TOTALIZER (6135) Select the option TOTALIZE
• Set the totalizer mode:
BASIC FUNCTION (G) PROFIBUS DP (GBA) TOTALIZER (613)
TOTALIZER MODE (6137) Selection of 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).
8. Select the operating mode:
Select the operating mode (GSD file) which should be used for cyclic communication with the
PROFIBUS master.
BASIC FUNCTION (G) PROFIBUS DP (GBA) OPERATION (614)
SELECTION GSD (6140) Selection of one of the following options:
– MANUFACT. SPEC. (factory setting): the complete device functionality is
available.
– MANUFACT V2.0 The device is used as the replacement for the previous Promag 33 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.
