Diagnostic: Other Faults
Functional Behavior:
The following diagnostic flags are set: “Failure Status” and “Watchdog Reset” (Bit 31 and Bit 8 are set to 1).
Causes and Triggers:
The diagnostic flag is set if the result of ProbeTempReadObjId, ProbeTempSetObjId,
PiezoStatusUAPObjId registration not successful. This is more like an extra software validation method to
assure that all the channels have a right object attached to it and there is no duplicate registration.
Diagnostic: Watchdog triggered device reset
Functional Behavior:
The following diagnostic flags are set: “Failure Status” and “Faults due to non- compliant operating
conditions” (Bit 31 and Bit 15 are set to 1).
Causes and Triggers:
The diagnostic flag is set if the application processor was reset due to a watchdog expiration. This can be
detected based on SYSRSTIV Register of the MSP430F5438A micro-controller.
Category 2: Functional Check
Diagnostic: Installation, Calibration Problem
Functional Behavior:
The following diagnostic flags are set: “Function Check Status” and “Installation, calibration problem”
(Bit 30 and Bit 25 are set to 1).
Causes and Triggers:
The diagnostic flag is set if one of the following conditions has been met.
• Low output from thermistor where T < -40°
• High output from thermistor where T > 200°
• Low output from piezo-electric transducer where there is no voltage output or Vout-piezo <= 1 mV
• RSQI with primary neighbor is low RSQI < 63.
• High PER (Packet Error Rate) where PER > 50%.
Diagnostic: Out of Service
Functional Behavior:
The following diagnostic flags are set: “Function Check Status” and “Out of service” (Bit 30 and Bit 24 are
set to 1).
Causes and Triggers:
The diagnostic flag is set if actual mode of AI Objects is Out Of Service.
Diagnostic: Software Update Incomplete
Functional Behavior:
The following diagnostic flags are set: “Function Check Status” and “Software Update Incomplete”
(Bit 30 and Bit 18 are set to 1).
Causes and Triggers:
The diagnostic flag is set when the remote OTA upgrade process of the application processor (through UD
mechanism) fails due to any reasons (ex. invalid image firmware, RF connection lost etc).
