10.3.3.9

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.
