Configuration of the Analog Input function blocks 1 to 2:
The measuring device has two Analog Input function blocks (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 (6123), you can determine the measured variable (e.g. volume
flow) to be cyclically transmitted to the PROFIBUS master (Class 1):
a. Select BASIC FUNCTION (G)
→
PROFIBUS PA (GCA)
→
FUNCTIONBLOCKS (612)
→
BLOCK SELECTION (6120).
b. Select the option ANALOG INPUT 1.
c. Select the function CHANNEL (6123).
d. Select the option VOLUME FLOW.
Possible settings:

Setting the measuring mode:
In the function MEASURING MODE (6601), select the flow portions to be measured by the
measuring device.

Selection of one of the following options:
– UNIDIRECTIONAL (factory setting) = only the positive flow portions
– BIDIRECTIONAL = the positive and negative flow components
7.
Configuration of Totalizers 1 to 3:
The measuring device has three totalizers. The following example describes the configuration
of the totalizer using Totalizer 1 as an example.
• 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.

The following measured variables are available when the additional "advanced diagnostic" software is
installed (order option)
DEVIATION COATING 1
2341
DEVIATION COATING 2
2358
DEVIATION ELECTRODE POTENTIAL 1
2375
DEVIATION ELECTRODE POTENTIAL 2

DEVIATION VOLUME FLOW
2419
DEVIATION NOISE VALUE

!
Note!
If, when the PROFIBUS network configuration, the AI module was integrated in slot 1 or 5, 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 2.
