Table 10-5 Error counter
Name Type Possible Values
(hex) Comment
FZP byte 0x00 ... 0xFF = Error counter, passive (errors during idle time)
ABZ = Abort counter
CFZ = Code error counter
SFZ = Signature error counter
CRCFZ = CRC error counter
BSTAT = Current command status
ASMFZ = Interface problems to host (CM/PC) parity, BCC, frame error
Note
Counter values are deleted.
Note that the counter values are deleted after they have been read out (command "Reader
status" or "SLG-STATUS").
Explanations:
• "FZP": counts interference pulses when communication with a transponder is not taking
place (e.g. electromagnetic interference caused by contactors, motors, etc.). Counter values
can, however, also be generated when a transponder is located at the edge of the field even
when there is no external interference.
• "ABZ", "CFZ", "SFZ" and "CRCFZ" are counters for protocol errors which may occur during
reader-transponder communication. This can be caused by unsuitable reader/transponder
positioning (e.g. transponder entering/leaving antenna field transponder on field boundary,
multiple transponders in the antenna field) or external EMC interference.
To ensure clear diagnostics of the quality of communication, it is recommended that a "Reader
status" (SLG STATUS) command with attribute "0x86" (mode 06) is executed following receipt of
the presence message to reset the error counters.
The protocol error counters are not mutually independent. If a code error (CFZ) occurs, this will
cause a signature (SFZ) or CRC- (CRCFZ) error.
• "BSTAT" is the status for the most recently executed command. A value other than 0 means
that the previous command was repeated by the reader due to faults (see above).
• "ASMFZ" signals line-conducted communication interference between the communication
module and the reader. Faults of this type can be caused by contact problems on the
connector or the cable connection.
10.2.3 Transponder diagnostics with "Tag status" (MDS-STATUS)
With this command you can query the status and diagnostics data from the transponder
currently located in the antenna field.
