Configuration of the Analog Input function blocks 1 to 3:
The measuring device has three Analog Input function block (AI modules), through which the
various measured variables can be cyclically transmitted to the PROFIBUS Master (class 1).
The assignment of a measured variable to the Analog Input function block is shown below
using the example of Analog Input function block 1 (AI module, slot 1).
Using the CHANNEL function, you can determine the measured variable (e.g. mass flow) to
be cyclically transmitted to the PROFIBUS Master (class 1):
a. Select COMMUNICATION
→
BLOCK SELECTION
b. Select the option AI1 - OUT VALUE
c. Select the function CHANNEL
d. Select the option MASS FLOW
6.
Configuration of totalizers 1 to 2:
The measuring device has two totalizers. The following example describes the configuration of
the totalizer using totalizer 1 as an example.
Using the CHANNEL function, you can determine the measured variable (e.g. totalized mass
flow) to be cyclically transmitted to the PROFIBUS Master (class 1) as a totalizer value:
a. Select TOTALIZER
→
SELECT TOTALIZER
b. Select the option TOTALIZER 1
c. Go to the function CHANNEL
d. Select the option MASS FLOW
• Enter the desired unit for the totalizer: TOTALIZER
→
UNIT TOTALIZER
• Configure totalizer status (e.g. totalize): TOTALIZER
→
SET TOTALIZER
→
Option: TOTALIZE
• Set the totalizer mode: TOTALIZER
→
MODE TOTALIZER: Select one of the following options:
– BALANCE (factory setting): calculates the positive and negative flow portions.
– POSITIVE: calculates the positive flow portions.
– NEGATIVE: calculates the positive flow portions.
– HOLD VALUE: The totalizer remains at the last value.
!
Note!
The device can’t calculate negative flow portions.

Note!
If, when the PROFIBUS network configuration, the module “AI” was integrated in slot 1, 2 or 3, the measured
variable selected in the CHANNEL function is transmitted cyclically to the PROFIBUS Master (class 1) for the
respective Analog Input function block 1 to 3 (

Note!
If, when the PROFIBUS network configuration, the module or the function “TOTAL” was integrated in slot 4 or 5,
the measured variable selected in the CHANNEL function is transmitted cyclically to the PROFIBUS Master
