MotoHawk:Blocks:Application Monitor

Application Monitor Definition

This MotoHawk™ block sets up the Continuous Built-In Tests (CBIT) in every MotoHawk application.

Block ID

motohawk_app_monitor

Library

MotoHawk_lib/System Debug Blocks

Description

This block is used to monitor the application's stack, heap, idle CPU usage, and OS errors for the 5xx processor modules. Upon discovery of a critical error, the application is stopped and certain actuators shut down safely. These currently include the Injector and Spark Sequence blocks. In the "System | Debug | Application Monitor" section, various display variables may be used to diagnose the problem.

At any time, the application is in one of four states: Init, Run, Pause, or Stop, and may be manually set from MotoTune. Init pauses after it has started up and before it runs any application code. Run has the program run until the application monitor is triggered for low stacks/heap, or high processor use. Pause, stops the application where it currently is in the app. Stop, stops the application where it is and puts all outputs in a safe state (this includes MPRD).

Modules

The Application Monitor Definition Block is supported on the 48, 80, and 128 pin ECUs. For the other modules, use the Second Generation Application Monitor Block instead.
