5.1.35 DWORD_TO_TIME(_E)
Outline
This function converts double word [unsigned]/bit string [32-bit] data into time data, and outputs the data
obtained by conversion.
1. Format
*1. Output variable
2. Set data
In explanation of functions, I/O variables inside ( ) are described.
Explanation of function and operation
This function converts double word [unsigned]/bit string [32-bit] data stored in a device specified in into
time data, and outputs the data obtained by conversion to a device specified in .
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.
