(1) Converts character strings stored in the device numbers starting from that designated at
the number of digits and BIN data in
For conversions from character strings to BIN, all data from the device number designated by
where "00 " is stored will be processed as character strings.

(2) The total number of characters that can be designated as a character string at
(3) From 0 to 5 characters from the character string designated at
However, this number must not exceed the total number of digits minus 3.
(4) The range of the numerical character string that can be converted to BIN value is from -32768 to 32767, ignoring a
decimal point.
Numerical value character strings, excluding the sign and the decimal point, can be designated only within the range
from "30 " to "39 ".

The value ignoring a decimal point means:
