25.39 Converting BCD to STRING
BCD_TO_STRING(_E)
These functions convert a value from BCD data type to STRING data type.
■Description, type, data type
■Operation processing
• These functions convert the value input to (s) from BCD (WORD or DWORD) data type to STRING data type, and output
the converted value from (d).
• WORD or DWORD data type can be specified for (s). BOOL data type cannot be specified.
• When SM701 (Number of output characters selection) is off, 00H is stored at the end of the string.
■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.
