8.2.1 Meaning of the status bits
Designation Meaning
Response code (RESC) Display of the last command executed
Contains in bit 14: ERROR
n 0: No (the last command was executed successfully)
n 1: Yes (an error occurred during command execution.)
Contains in bit 15: BUSY
n 0: No (execution of a command completed.)
n 1: Yes (command active but not yet completed; system is waiting for execu-
tion, e.g. on tag within the detection range)
Loop counter for rapid
processing (RCNT)
Output of the loop counter for the selected command code
Expected read/write head not
connected (TNC1)
0: No (read/write head expected by system connected)
1: Yes (read/write head expected by the system not connected (HF bus mode: At
least one read/write head expected by system not connected)
Error reported by read/write
head (TRE1)
0: No (no error)
1: Yes (fault signal of the read/write head) (HF bus mode: fault signal from at least
one read/write head)
Parameter not supported by
read/write head (PNS1)
0: No (no error)
1: Yes (parameter not supported by read/write head) (HF bus mode: Parameter
not supported by at least one read/write head)
Read/write head not tuned (XD1) 0: No (no error)
1: Yes (read/write head not tuned) (HF bus mode: at least one of the read/write
heads not tuned)
Tag in the detection range of
read/write head (TP)
0: No (no tag in the detection range of the read/write head)
1: Yes (tag in the detection range of the read/write head) (HF bus mode: tag in
the detection range of at least one read/write head)
HF read/write head switched on
(TON)
0: No (read/write head switched off)
1: Yes (read/write head switched on (HF bus mode: at least one read/write head
switched on)
Continuous (Presence Sensing)
Mode active (CMON)
0: No (Continuous Mode not active)
1: Yes (Continuous 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. With HF multitag applications and UHF, the rising
edges of the tags that are read by an Inventory command are counted. In HF
single-tag applications, all tags that are detected by the read/write head are
counted. A tag that moves along the read/write head is not counted again if it
only leaves the detection range momentarily and re-enters it (within the set by-
pass time). If a tag continuously remains within the detection range, it is also only
counted once. Exceptions: Continuous Mode in bus mode is active or Continuous
Mode with start address = 3 is active.
The tag counter is reset by the following commands:
n Inventory (exception: HF single-tag applications)
n Continuous Mode
n Continuous Presence Sensing Mode
n Reset
