4.12 Program Calculated Values
A Calculated Value (CV) is a data point whose value is derived from calculations involving other data
points. The CV Output can be analog or discrete. A CV can include other CVs in its calculations. Once a
CV is created, it can be used by any function block as many times as desired.
Select "CALCULATED VALUES" on the Main Program Menu. Select a CV to program, then choose
from the types shown in
points. The CV Output can be analog or discrete. A CV can include other CVs in its calculations. Once a
CV is created, it can be used by any function block as many times as desired.
Select "CALCULATED VALUES" on the Main Program Menu. Select a CV to program, then choose
from the types shown in

ATTENTION
•
If you plan to program another function block using a Calculated Value as a parameter, you must program
the Calculated Value first.
