readTagField
This command reads data from the selected transponder. The address of the data area is
specified by the name of a tag field. The tag field and the name of the field are specified
using the WBM. If no EPC-ID is made available or detected, the command is executed with
all the transponders recognized from the read point.
Note
If no EPC-ID is specified, the results are influenced by all the set filter mechanisms (refer to
the section "The "Settings - Filters" menu item (Page 68)"). Then in the reply frame, only the
tags that were not filtered out appear. If an EPC-ID is specified, the data filter has no effect.
The reply frame contains the IDs of all identified transponders. A flag for each transponder
indicates whether or not the command was successful for this transponder.
If no transponder was identified, a negative reply is returned.
