Converting STRING to DINT

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

Processing details
■Operation processing
• These functions convert the value input to (s) from STRING data type to DINT data type, and output the converted value
from (d).

• Input a STRING data type value to (s) within the following range.
• ASCII code: 30H to 39H, 20H, 2DH, and 00H
• STRING data type value: -2147483648 to 2147483647
■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.
