Parameters

Id [C:short] [Python: ctypes.c_short]
Specifies the device ID retrieved from DioInit.

PortNo [C:short] [Python: ctypes.c_short]
Specifies the logical output port number.
The logical output port number is a number, which is assigned from the first output port of the device as 0 to the last one serially.

Data [C:unsigned char] [Python: ctypes.c_ubyte]
Specifies the output datum.
