Configuration of the Analog Input function blocks 1 to 8:
The measuring device has eight Analog Input function blocks (AI modules) via 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
CHANNEL 1) to be cyclically transmitted to the PROFIBUS master (Class 1):
a. Select BASIC FUNCTION (G)
→
PROFIBUS DP (GBA)
→
FUNCTIONBLOCKS (612)
→
BLOCK SELECTION (6120).
b. Select the option ANALOG INPUT 1.
c. Select the function CHANNEL (6123).
d. Select the option VOLUME FLOW CHANNEL 1.

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

Note!
If, when performing the PROFIBUS network configuration, the AI module was integrated in slot 1 to 8, the measured
variable selected in the CHANNEL function for the respective Analog Input function block 1 to 8 is transmitted cyclically
to the PROFIBUS master (Class 1)
