6 BASIC INSTRUCTIONS
6.6 Data Conversion Instructions
• If "20H" (space) or "30H" (0) exists between the sign and the first numerical value other than 0 in the character string in the
device specified by (s), the instruction performs conversion to binary data by ignoring "20H" and "30H".
Ex.
When "20H" exists between the sign and the first numerical value other than 0 (when a signed value is specified)
Ex.
When "30H" exists between the sign and the first numerical value other than 0
Operation error
Error code
(SD0)
Description
2820H 00H is not set between the device number specified by (s) and the last device number of the relevant device.
3401H Invalid data that cannot be converted are input in (s).
• The number of characters of the character string is not between 2 and 13.
• The number of characters in the decimal part of the character string is not between 0 and 10.
• The relationship between the total number of characters and the number of characters in the decimal part is not in the following range.
Total number of characters - 3number of characters in the decimal part
• When the DVAL(P) instruction is used, an ASCII code other than "20H" and "2DH" is set as a sign.
• When the DVAL(P)_U instruction is used, an ASCII code other than "20H" is set as a sign.
• An ASCII code other than "30H" to "39H" and "2EH" (decimal point) is set as a digit of individual numbers.
• More than one decimal point are set.
The converted binary value exceeds the range in which each instruction can implement conversion.
3405H The number of characters of the character string in the device specified by (s) exceeds 16383.
