Totalizer Function Block - Siemens SITRANS P DS III Operating Instructions Manual

Using the target mode selected in Mode and status processing, you can choose between
output of the automatically acquired measured value (AUTO setting) or a manually set
simulation value (MAN setting). If the function block is out of order (O/S setting) then the
safety preset value is always output.
The analog input function block handles the numerical value separately from the physical
unit. This allows you to set 1000 predefined units.
