Analog input function block
The Analog input function block provides the content of the "Output" parameter. The
Totalizer function block provides the content of the "Totalizer output" parameter. You can
select in the configuration which function block is used to generate the output data:
● Output
● Totalizer output
In the "Totalizer output" parameter you can insert the following additional functions:
● Reset totalizer output
● Operating mode
Using "Reset totalizer output" you can reset the integrator from the application program, and
with "Operating mode" you can determine its function.
Note
For STEP 7, the configuration tool is HW Config.
For STEP 5, the configuration tool is COM_PROFIBUS.
