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 op-
erations 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
