getObservedTagIDs

With this command, the selected read point takes an inventory and returns all identified
transponders in the reply frame.
In contrast to the "readTagIDs" command, the smoothing algorithm of the selected read point
is also affected here. The read point must therefore take enough inventories until a
transponder adopts the "Observed" status. This can be achieved by selecting the suitable
parameter values or by triggering/starting the read point in good time before the command.
If no transponder was identified with the "Observed" status, a positive reply without
transponder data is returned.
To be reported, a transponder must have had the "Observed" status at least once at the start
of or during the command execution time. The transponder is reported even if it returned
temporarily to the "Lost" status.
The command remains active during the entire duration. In the implementation of the client
application, make sure that timeout monitoring is used. The configuration parameters of the
data source (read cycles per trigger, read timeout, ...) are not used. You will find more
