RML Module 110 Chapter 6 Features
Variable Function
This function simply passes the stored value to its
output.
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
A variable function block is used to store a user sup-
plied value and provide a source input to another
function block with that value. As an example, you
could use a variable function value as one input to
a compare function. The other input to the compare
function would determine the output value based on
the user's supplied value.
