EXCERPT:
Frames
Every few seconds the system also collects frames which are bits of time. The time duration of each frame is set using the PTU in increments of 0.01 seconds. Frames are collected right after all of the systems' input/output functions (events) are complete, as a record of system function at the time of the event.
Each frame contains 40 floating point values, all digital input and output values, the state machine's current state at the time of the event.
Each time an event is reported, a frame (known as the trigger frame) is kept for that event until the event is erased.
Windows
Some events may also have frame windows - a collection of 51 frames, that is, all the frames that occur for 40 frames before the event, a frame at the event, and 10 frames after the event.
The system will save each event window for the first 16 events that are qualified to have windows. They will be saved until the event is erased. After 16 windows are stored, no additional windows can be stored.
System Categories
All of the possible events which can occur have been programmed to fall into eight different categories to enable the system to respond correctly. They are:
Active Events Count
This is the current number of events of this type which are active, i.e., which may affect truck operation.
Decay Active Events Count Time
This is the time in seconds which specified the rate at which the active events count decays, allowing a certain number of events to occur normally over a given time frame without affecting truck operation.
Lockout DOS Limit
This controls how often a truck operator may reset the operating restrictions caused by an event type, using the Dump Override Switch (DOS) in the cab.
If the active events count is equal to the lockout DOS limit for a given type, the override switch (DOS) will have no effect on operating restrictions caused by that event. The active events count for that type will not be decayed by the decay active events count.
Running Count
This is the total count of all events of this type seen since running count was last cleared by the PTU.
Life Count
This is the total count of all events of this type ever recorded. The maximum number which can be recorded is 4,294,967,295. When this number is reached, the count will roll over.
Accept Limit
This is the number of events of this type that will be recorded by the system. See the discussion under Limits On Resetting Faults.
Window Captures Allowed Limit
This tells how many windows will be captured for events of this type, subject to space restrictions. When the window capture limit is exceeded, only a single frame of data is saved.
Window Captures Count
This is the count of windows saved for this event type. This value is incremented by one each time a window is saved for this event type. It is decremented or cleared when events are cleared by the PTU.
Limits On Resetting Faults
In the fault system, there are three limits associated with resetting faults:
Accept limit (accept_limit)
This is the limit on the number of faults which may be stored. When the limit of a given fault is exceeded, the oldest event of this type recorded without a window will be replaced with the new event, it will not be overwritten. The system does not allow events with windows to be overwritten. If the oldest event has a window, the oldest non-window event will be overwritten.
