Error Numbers
The BIS C-600 always outputs an error number. The meaning of these error numbers is
indicated in the following table.
No. Error Description
Effect
1
No data carrier present
Telegram aborted,
processor goes into ground state.
2
Read error
Read telegram aborted,
processor goes into ground state.
3
Read aborted, since the
data carrier was
removed.
Processor goes into ground state.
4
Write error
Write telegram aborted,
processor goes into ground
state.
CAUTION:
An aborted write
could cause new data to be
written to the data carrier
which may be incomplete! *)
5
Writing aborted,since the
data carrier was
removed.
Processor goes into ground
state.
6
Interface error
Processor goes into ground state.
(parity or stop bit error)
7
Telegram format error
Processor goes into ground state. Possible format errors:
- Command is not 'L'/'P'/'C'/'R'/'W'/'H'/'B'/'Q'/'S'/'Z'.
- Start address or number of bytes exceed permissible range
*)
Note:
If a CRC data check is used, error message “E” could result if error 4 or 5 was not
cleared.

8
BCC error, the trans-
mitted BCC is wrong.
Telegram is aborted,
processor goes into ground state.
9
Cable break from
read/write head or
cable not connected,
Codetag Present
LED flashes.
Telegram is aborted,
processor goes into ground state.
If both read/write heads were selected using 'HT', one
head may not be connected. If both read/write heads are
selected, the cable break message only comes if there is
no data carrier in front of the connected, functional head.
A
New command not
possible, since a read
command is already in
process.
After error message the read command is stopped,
internally, but not acknowledged.
Processor goes into ground state.
B
New command not
possible, since a write
command is already in
process.
After error message the write command is stopped,
internally, but not acknowledged.
Processor goes into ground state.
C
New command not
possible, since a head
select is already in process.
After the error message, no positive acknowledge is given,
even thought the head select was successful.
Processor goes into ground state.
E
CRC error: the CRC on the
data carrier is wrong.
*)
Telegram aborted,
processor goes into ground state.
I
EEPROM error
Telegram aborted,
processor goes into ground state.
*)
Note:
If a CRC data check is used, error message “E” could result if in the preceding command
error 4, 5 or B was reported.
