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
