(4) Local Display transducer block (LTB)
• Controls the display.
(5) Maintenance transducer block (MTB)
• Is related to settings for detailed device information and manufacturing.
• Has functions to display device information (detailed version of the device, serial No.
information, etc.), information related to event management (backup/restore, data logging
function), application for service/factory/expert (for debugging, manufacturing), alarm/error
log and software download results.
(6) AI function block (AIFB) (AXG: 4, AXW: 3)
• Outputs various flow rates (including flow velocity), calorie and totalized value.
• For AXG, outputs the adhesion resistance, electrode potential, flow noise and conductivity.
• Performs processing such as the SIMULATE function, damping (first-order lag filter),
scaling, etc.
(7) Dl function block (DIFB) (3)
• Performs discrete output for the process value, alarm and warning of STB and DTB.
(8) PID function block
• Performs the PID control computation based on the deviation of the measured value from
the setpoint.
(9) MAO function block (only AXG)
• Inputs a temperature value from other device.
(10) IT function block (2)
• Adds two main inputs and integrates them for output.
(11) AR function block
• Switches two main inputs of different measurement ranges bumplessly and combines the
result with three auxiliary inputs through the selected compensation function to calculate the
output.
