26 Character String Control – FNC200 to FNC209
26.2 FNC201 – VAL / Character String to BIN Conversion
5) [ +1, ] stores 16-bit data (bin) converted from a character string with the decimal point ignored.
For the character string located in and later, the "space" (20H) and "0" (30H) characters between the sign
and the first number other than "0" are ignored in the conversion to 32-bit binary data.

Caution
Store sign data, "space (20H)" or "- (2DH)", must be stored in the 1st byte (lower order 8 bits of the head device set
in ).
Only the ASCII code data "0 (30H)" to "9 (39H)", "space (20H)" and "decimal point (2EH)" can be stored from the 2nd
byte to the "00H" at the end of the character string in .
If "- (2DH)" is stored in the 2nd byte or later, an operation error (error code: K6706) occurs.
Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is stored in
D8067.
• When the number of characters of the character string to be converted ( and later) is outside the following
ranges (error code: K6706)
• When the number of characters after the decimal point of the character string to be converted ( and later) is
outside the following ranges (error code: K6706)
• When the relationship between the number of all characters in the character string to be converted ( and
later) and the number of characters after the decimal point does not satisfy the following (error code: K6706)
(Number of all characters -3) ≥ Number of characters after the decimal point
• When the sign is set to any ASCII code other than "space" (20H) and "-" (2DH) (error code: K6706)
• When a digit of a number is set to any ASCII code other than "0" (30H) to "9" (39H) or a decimal point "." (2EH)
(error code: K6706)
• When the decimal point "." (2EH) is set two or more times in the character string to be converted ( and later)
(error code: K6706)
• When the binary data acquired by conversion is outside the following range (error code: K6706)
• When "00H" is not present in the location from to the final device number (error code: K6706)
