Processing details
■Operation processing
Converts word (unsigned)/16-bit string type data input to (s) into double word (unsigned)/32-bit string type data, and outputs
the operation result from (d).
After data conversion, high-order 16 bits are filled with 0s.
s
5678
H
Word (unsigned)/16-bit string type
■Operation result
• Function without EN/ENO
An operation is executed and the operation value is output from (d).
• Function with EN/ENO
The following table shows the executing conditions and operation results.
EN
TRUE (Operation execution)
FALSE (Operation stop)
*1 When FALSE is output from ENO, the data output from (d) is undefined. In this case, create a program so that the data output from (d) is
not used.
