Channel functions can be assigned units of measure for linear, angular
or temperature values, or can be numeric (no unit of measure). Units
of measure can be assigned by supervisors using the Channels setup
screen.
Channel functions used as variables in formulas can be:
„ Direct from the channel inputs
„ Level adjusted and calibrated by the Master function or error
correction
„ Given linear, angular or temperature units of measure
Insert channel functions into formulas to include channel values in
dimensions.
To insert a channel into a formula:
U Press the CHAN... soft key
U Press the dimension key for the channel you would like to insert
Channel values can be assigned directly by making a dimension equal
to a channel function or can be used in calculations as shown below:

Channel inputs are processed before becoming channel functions
that are used in formulas.
Directly assigned channel function.
Example 1: Directly assigned.
A=C1
Example 2: Used in Calculation.
A = (Pi*(C1exp2))/4
Where:
A = Area
C1 = Diameter of a circle
