The Math function block accepts multiple inputs and per-
forms a programmed math function to derive an output
value with Filter and Offset values applied. Some math
operations must be performed in the user's units.
Functions may combine multiple inputs. Those inputs may
have incompatible units from a logical point of view. As a
result, unless otherwise indicated, the presentation of the
output value is the same as Source A. This accommodates
temperatures being multiplied, divided and offset by con-
stants and process inputs.
Only inputs pointed to a source are used in the calcula-
tions.
An error, when read, can indicate any of the following:
None, Open, Shorted, Measurement Error, Bad Cal Data,
Ambient Error, RTD Error, Fail, Math Error, Not Sourced,
Stale
