Limit Function
This function uses a dedicated input and the output
will change state when Source A exceeds limit set
points. The limit, when tripped, must be manually
cleared to reset the output and clear the message.
The Analog Input and mechanical relay output are
dedicated to each limit loop and are located in same
module.

Linearization Function
This function will take an analog Source A and re-
linearize using a 10-point offset, then add Offset and
produce an Output Value.
An error, when read, can indicate any of the follow-
ing: None, Open, Shorted, Measurement Error, Bad
Cal Data, Ambient Error, RTD Error, Fail, Math Er-
ror, Not Sourced, Stale
