Explanation of function and operation
This function converts word [signed] data stored in a device specified in
string [32-bit] data, and outputs the data obtained by conversion to a device specified in
-325
0000FEBBH
0
Each of high-order 16 bits becomes
"0" after data conversion.
Cautions
1) Use the function having "_E" in its name to connect a bus.
2) When handling 32-bit data in structured programs, you cannot specify 16-bit devices directly, different
from simple projects. Use labels when handling 32-bit data.
You can specify 32-bit counters directly, however, because they are 32-bit devices.
