The table below lists the fields from the detail section and the contents of each field.
Heading
Contents of Field
Car
The car number as determined by the firmware.
Axle
The axle number.
Rail
Under it are two columns, one for each rail, containing the temperature read
by the bearing scanners. If the track orientation is east and west, rails are
north and south. If the track orientation is north and south, rails are east and
west.
Wheel
Under it are two columns, one for each rail, containing the temperature read
by the wheel scanners. If the track orientation is east and west, rails are
north and south. If the track orientation is north and south, rails are east and
west. This heading and the two columns under it appear only when
Hotwheel alarm reporting is enabled using the
Hotwheel option
on the
Equipment submenu.
ON
The number of milliseconds a bearing was scanned.
OFF
The number of milliseconds between bearings (when no bearing was
between the gating transducers).
PW1
The recorded pulse width generated by gating transducer TO1. There is no
fixed value for the pulse widths. Slower trains generate wider pulse widths
(that is, they generate larger values) than faster moving trains.
PW2
The recorded pulse width generated by gating transducer TO2. There is no
fixed value for the pulse widths. Slower trains generate wider pulse widths
(that is, they generate larger values) than faster moving trains.
TxdHits
TO1
The total number (for a given axle) of interrupt firings for gating transducer
TO1. Since each interrupt fires once on a signal's rising-edge and once on a
signal's falling-edge, this value should be two. Values higher than two can
indicate additional interrupt firings, possibly from a transducer spike, or a
missed axle on the opposite transducer.
TxdHits
TO2
The total number (for a given axle) of interrupt firings for gating transducer
TO2. Since each interrupt fires once on a signal's rising-edge and once on a
signal's falling-edge, this value should be two. Values higher than two can
indicate additional interrupt firings, possibly from a transducer spike, or a
missed axle on the opposite transducer.
Alarms
Any Exception Alarm found on the given axle.
