• Flag
The meanings of the flags are given on the table below. The flags are valid during
FIFO data output. The flags are undefined for other cases.
Bit Flag Flag Meaning of the Flag
0 1
6 – –
5 – –
4 – –
3 – –
2 No Yes Indicates that the decimal position or unit information was
changed during measurement.
1 No Yes Indicates that the FIFO acquiring interval was changed during
measurement.
0 No Yes Indicates that the internal process took too much time
(computation, for example) and that FIFO dropout occurred.
The bits that have “–” for the flag column are not used. The value is undefined.

BINARY
value 0 to 8 is entered in the upper and lower 4 bits of a byte (8 bits) for the alarm
status. The binary values 0 to 8 correspond to H (high limit alarm), L (low limit alarm), h
(difference high-limit alarm), l (difference low-limit alarm), R (high limit on rate-of-change
alarm), r (low limit on rate-of-change alarm), T (delay high limit alarm), and t (delay low limit
alarm) as follows:
0: no alarm, 1: H, 2: L, 3: h, 4: l, 5: R, 6: r, 7: T, and 8: t.
• Special Data Value
The measured/computed data take on the following values under special conditions.
Special Data Value Measured Data Computed Data
+ Over 7FFFH 7FFF7FFFH
– Over 8001H 80018001H
Skip 8002H 80028002H
Burnout (when “up” is set) 7FFAH 7FFF7FFFH

Error 8004H 80048004H
Undefined 8005H 80058005H
Note
The number of blocks, number of bytes, and measured/computed data are output according to
the byte order specified with the BO command.
