Sample Tag Configurations
See the following sample tag configurations:
 Scan Classes (page 27)
 Polled Tags (page 27)
 Advise Tags (page 28)
 Event Tags (page 28)
Scan Classes
Scan classes are defined in the startup file. Each /F= parameter defines a
scan class, which is numbered in order.
For example, if the .bat file reads
/F=2 /F=1:00 /F=1:30:00 /F=00:00:05,00:00:01
then these scan classes have been defined:
 Scan Class 1 has a scan period of 2 seconds.
 Scan Class 2 has a scan period of 60 seconds.
 Scan Class 3 has a scan period of 5400 seconds (90 minutes).
 Scan Class 4 has a scan period of 5 seconds, with an offset of 1
second.
Polled Tags
Polled tags are read once every scan period. To set up a polled tag, set
Location1 to match the /ID parameter, Location3=0, and
Location4=scanclass#.
For example:
Tag InstrumentTag Loc1 Loc2 Loc3 Loc4 Loc5
