writeTagField

This command writes data to 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 60)"). 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.

Description
Memory bank of the transponder
0: Reserved
•
1: EPC
•
2: TID
•
3: USER MEMORY
•
Start address of the first byte in the
memory bank where reading will start.
Number of bytes to be read.
Data that should be read. Each byte is
represented by two hexadecimal char-
acters.
Example:
The byte sequence "0x12, 0x34, 0xA3"
is represented as the character string
"1234A3" in the "value_data" parame-
ter.
"value_dataLength" is 3 in this exam-
ple.
If the transponder is identified but the
data cannot be read (e.g. if the tran-
sponder has no user memory as re-
quired), this field remains empty.
"value_success" is then set to "False".
