8. SPOT TAGS<br />
Spot tags are <strong>AEI</strong> tags that are programmed with track spot location information.<br />
Their purpose is to eliminate the need to manually enter track spot information when<br />
taking track inventory.<br />
Before reading Spot tags, the operator would read the Track tag at his starting point<br />
on the track.<br />
Prior to reading the tag on the rail vehicle the Spot tag for the vehicle's location should<br />
be read. When the rail vehicle's tag is read, the vehicle's location will be determined<br />
by the information in the last Spot tag read.<br />
Spot tags contain the track name associated with the spot location and the spot<br />
name.<br />
Spot tags are standard AT5110 or AT5118 tags that are programmed in ASCII. The<br />
following table is the format of the Spot tag:<br />
Field Starting<br />
Position<br />
Field Size Data<br />
Tag Type Identifier 1 4 SPOT<br />
Track Name 5 10 Up to 10<br />
alpha/numeric<br />
characters<br />
Spot Name 15 5 Up to 5<br />
alpha/numeric<br />
characters<br />
Examples:<br />
