Converting WORD to DWORD

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

Processing details
■Operation processing
• These functions convert the value input to (s) from WORD data type to DWORD data type, and output the converted value
from (d).
• After the data type is converted, the upper 16 bits are filled with 0s.
(s)
5678H
WORD
• Input a WORD 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
There is no operation error.
