Description Meaning
Read fragment No. (RFN) If the data to be read exceeds the size of the read data memory, the data is split
into max. 256 fragments. The fragments are numbered consecutively from 1 to
255. From fragment number 256, numbering begins again at 1. The sending of a
fragment is confirmed by the device if the read fragment No. appears in the
process input data. After the confirmation, the next fragment is read.
0: No fragmentation
In idle mode, the size of the fragments is specified. When a read command is
issued, the fragment No. of the access to the read data of the next fragment is
set.
Write fragment No. (WFN) If the data that is to be written exceeds the size of the write data memory, the
data is split into max. 256 fragments. The fragments are numbered consecutively
from 1 to 255. From fragment number 256, numbering begins again at 1.
The sending of a fragment is confirmed by the device if the write fragment No.
appears in the process input data. Following confirmation, the next fragment is
written.
0: No fragmentation
In idle mode, the size of the fragments is specified. When a write command is
issued, the fragment No. for the next fragment for the data to be written is set.
Read/write head address HF bus mode: Address of the read/write head, if several bus-capable read/write
heads are connected
UHF: Values are ignored or set automatically.
Write data User-defined write data or entry of a UID or EPC to select a specific tag for the
command execution (if the "UID/EPC (SOUID) length" command parameter is
greater than 0)
