(2 bytes): Process variable
-
32000
to +
32000
(2-byte hexadecimal data)
The higher and lower bytes can be reversed by the BO command.
If Skip is specified,
8080
H will be outputted.
[Note]
(1) Output data over -
32000
to +
32000
constitutes overflow. The overflow 7E7E is output on the
plus side, and 8181 is output on the minus side (Excluding the Decade channel).
(2) Irrespective of the BO command, data output of the Decade channel is as follows. The upper
byte outputs a mantissa (10 to 99). The lower byte outputs an exponent (-19 to 19). A decimal
point position is fixed on the 1 digit after the decimal point.
