Meaning of the status bits
Default values are shown in

type.
Designation
Meaning
Response code (RESC)
Display of the last command executed
Loop counter for rapid
processing (RCNT)
Output of the command code requested by the loop counter
Read/write head reports error
(TRE1)
0: No error
1: Error message of the read/write head
Parameter not supported by
read/write head (PNS1)
0: No error
1: Parameter not supported by read/write head
Tag within the detection range
(TP1)
0: No tag in detection range of read/write head
1: Tag in detection range of read/write head
Continuous presence sensing
mode active (CMON)
0: Continuous presence sensing mode not active
1: Continuous presence sensing mode active
Length (LEN)
Display of the length of the read data
Error code (ERRC)
Display of the specific error code if the error bit (ERROR) is set.
Tag counter (TCNT)
Display of the detected tags read with an Inventory command. The tag counter is
reset by the following commands:
n
Inventory
n
Continuous presence sensing mode
n
Reset
Data (bytes) available (BYFI)
(only available with UHF
extended)
Shows the number of bytes in the FIFO memory of the interface.
Ascending: New data from a tag read or received by the device
Descending: Execution of a command completed
Error message 0xFFFF: Memory overfilled, data loss of new data likely
Read fragment no. (RFN)
(only available with UHF
extended)
If the data to be read exceeds the size of the read data memory, the data is di-
vided in max. 256 fragments. The fragments are numbered consecutively from
1…255. From fragment number 256 numbering starts again at 1. The sending of
a fragment is confirmed by the device if the read fragment number appears in
the process input data. After the confirmation the next fragment is read.
0: No fragmentation
In Idle mode the size of fragments is stated. With a read command the number of
fragments containing data is stated.
Write fragment no. (WFN)
(only available with UHF
extended)
If the data to be written exceeds the size of the write data memory, the data is
divided in max. 256 fragments. The fragments are numbered consecutively from
1…255. From fragment number 256 numbering starts again at 1.
The sending of a fragment is confirmed by the device if the write fragment num-
ber appears in the process input data. After the confirmation the next fragment
is written.
0: No fragmentation
In Idle mode the size of fragments is stated. With a write command the number
of fragments containing data is stated.
