Transducer Block
• Contains the actual temperature measurement data, including Sensor 1,
Sensor 2, and terminal (body) temperature
• Includes information about sensor type and configuration, engineering
units, linearization, range, damping, and diagnostics
LCD Block (when an LCD display is used)
• Configures the local display
Analog Input (AI)
• Processes the measurement and makes it available on the fieldbus
segment
• Allows filtering, engineering unit, and alarm changes
PID Block (provides control functionality)
• Performs single loop, cascade, or feedforward control in the field
