Processing details
■Operation processing
• These functions convert the WORD type data input to (s) to DWORD type data and output from (d).
• Each of high-order 16 bits becomes "0" after data conversion.
(s)
5678H
WORD
• A value input to (s) is the WORD type data value.
■Operation result
1.
Function without EN/ENO
The operation processing is executed. The operation output value is output from (d).
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
Execution condition
EN
TRUE (Executes operation)
FALSE (Stops operation)
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
Operation error
There is no operation error.
