Processing details
■
Operation processing
• These functions convert the value input to (s) from DINT data type to STRING data type, and output the converted value
from (d).
• Input a DINT data type value to (s).
• As sign data, 20H (space) is stored if the input value is positive, and 2DH (-) is stored if the value is negative.
• If the number of digits in the input value is less than the number of significant digits, 20H (space) is stored for the upper
digit(s).
Ex.
When the value -123456 is input
• When SM701 (Number of output characters selection) is off, 00H is stored at the end of the string (upper bytes of the 6th
word).
■ Operation result
1.
Function without EN/ENO
The operation processing is performed. The operation result is output from (d).
2.
Function with EN/ENO
The execution conditions and operation results will be as follows.
*1 If the value FALSE is output from ENO, the output data from (d) will be undefined. Create a program so that the undefined value will not
be used in operations.
Operation error
There is no operation error.
