5.1.5 BOOL_TO_DWORD(_E)
Outline
This function converts bit data into double word [unsigned]/bit string [32-bit] data, and outputs the data
obtained by conversion.

Explanation of function and operation
This function converts bit data stored in a device specified in into double word [unsigned]/bit string [32-
bit] data, and outputs the data obtained by conversion to a device specified in .
When the input value is "FALSE", this function outputs "0H" as the double word [unsigned]/bit string [32-
bit]data value.
When the input value is "TRUE", this function outputs "1H" as the double word [unsigned]/bit string [32-bit]
data value.
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.
Use global labels when specifying labels.
