Converting STRING to WORD

STRING_TO_WORD(_E)
RnPCPU
RnCPU RnENCPU
(Process)
These functions convert a value from STRING data type to WORD data type.

Processing details
■Operation processing
• These functions convert the value input to (s) from STRING data type to WORD data type, and output the converted value
from (d).
(s)
0000
0012
STRING
• Input a STRING data type value to (s).
■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.
Execution condition
EN
TRUE (executed)
FALSE (not executed)
*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
Error code Description
(SD0)
3401H An ASCII code other than 30H to 39H and 41H to 46H is input.
