This function also allows batch operation of the reader when there is a connection to the
user application at certain times. The reader collects the frames and these can, when
necessary, be called up using a PC application.
Tag events / tag commands
Tag events signal identified transponders or when they have left the antenna field.
Information on all activated tag events is reported by the reader to the XML API interface.
The triggers for messages are the following event types:
● Glimpsed
Transponder was scanned the first time.
● Observed
The transponder was identified reliably for at least "x" read cycles. You can set the
number "x" in the section "The "Settings - Read points" menu item (Page 46)" in the area
"Algorithmen > Smoothing > Observed Count" (default value = 1).
● Lost
The transponder was no longer identified reliably for at least "x" read cycles. You can set
the number "x" in the section "The "Settings - Read points" menu item (Page 46)" in the
area "Algorithmen> Smoothing Lost Count" (default value = 5).
Note that with the events, only the activated data of the transponder is reported.
The data enabled in this area also affects the message content of the XML commands/reply
frames (e.g. with "writeTagID").

Not every XML command/event report provides information about all the data activated here.
You will find information indicating which XML commands/event reports provide data in the
