Verify transmitter configuration
Each FOUNDATION Fieldbus host or configuration tool has a different way of
displaying and performing configurations. Some use Device Descriptions (DD) or
DD methods for configuration and to display data consistently across platforms.
There is no requirement that a host or configuration tool support these features.
The following is the minimum configuration requirement for a temperature
measurement. This guide is designed for systems not using DD methods. For a
complete list of parameters and configuration information refer to the
Rosemount 3144P Temperature Transmitter Reference Manual.
3.2 Transducer function block
This block contains temperature measurement data for the sensors and the
terminal temperature. It also includes information about sensor types,
engineering units, damping, and diagnostics. At a minimum, verify the
parameters in Table 1.
Analog Input (AI) function block
The AI block processes field device measurements and makes the outputs
available to other function blocks. The output value of the AI block is in
engineering units and contains a status indicating the quality of the
measurements. Use the Channel number to define the variable that the AI block
processes. At a minimum, verify the parameters of each AI block in Table 2.
Note
All devices ship with the AI blocks scheduled, meaning no configuration is needed if the factory
default channels are used.
