(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owrates(includingowvelocity),calorieandtotalizedvalue.
• ForAXG,outputstheadhesionresistance,electrodepotential,ownoiseandconductivity.
• PerformsprocessingsuchastheSIMULATEfunction,damping(rst-orderlaglter),
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di󰀨erentmeasurementrangesbumplesslyandcombinesthe
result with three auxiliary inputs through the selected compensation function to calculate the
output.
