Functional Modules
Resource Module
Includes physical information of the Rosemount 3144P temperature transmitter, including: maximum memory, manufacturer identification, device type, software label, and unique identifier.
The plant network alarm system can fully utilize the digital system of the plant network by diagnosing instrument issues, providing detailed communication, and suggesting solutions.
Sensor Module
Contains actual temperature measurement data, including Sensor 1, Sensor 2, and terminal temperature.
Includes the following information: sensor type and configuration, technical units, linearization, range, attenuation, and diagnostics.
LCD Module (when using an LCD display)
() Configures the local display.
Analog Input (AI)
Processes measurement results and makes them available for fieldbus program segments.
Filter, technical units, and alarm settings can be modified.
Process Identifier Module (provides control functions)
Executes single-loop, cascade, or feedforward control in the field.
Instantaneous Functional Modules
All functional modules used by the transmitters are instantaneous modules, meaning: the number of functional modules is only limited by the physical memory in the transmitter. Combinations of functional modules can be used as long as they do not exceed the physical memory at any given time.
Rosemount 3144P Temperature Transmitter Fault Modes!
The Rosemount 3144P temperature transmitter has software and hardware fault mode detection capabilities. When the microprocessor hardware or software fails, a designed independent circuit can provide backup alarm output. Users can select alarm levels through the fault mode switch. If a fault occurs, the hardware switch position points to the drive output direction (high or low). The switch feeds information to the digital-to-analog converter, which can drive the correct alarm output even if the microprocessor fails. The transmitter’s drive output value depends on whether its operating system is configured as standard or compliant with NAMUR (configured according to NAMUR recommendation NE 21, 1999). The values for standard configuration and NAMUR-compliant operating systems are as follows:
HART communication requires a loop resistance of 250 to 1,100 ohms. Communication with the transmitter is prohibited when the terminal voltage of the Rosemount 3144P temperature transmitter is below 12Vdc.
