Math Function
The Math function block accepts up to 4 Analog Inputs and
performs a programmed math function to derive an output
value with Filter and Offset values applied. One digital in-
put is used for enabling or disabling Process and Deviation
Scale and 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 constants and pro-
cess 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
