CntOutputDOBit

Function

Executes the general-purpose output. Supports multi-processing.

Format

Ret = CntOutputDOBit ( Id , ChNo , Reserved , OutData )

Parameters

Id [ C, C++ : short] [Python: ctypes.c_short]
Specify the device ID retrieved from CntInit.

ChNo [ C, C++ : short] [Python: ctypes.c_short]
Specifies the channel number which you want to set.

Reserved [ C, C++ : short] [Python: ctypes.c_short]
Specify 0.

OutData [ C, C++ : unsigned char] [Python: ctypes.c_ubyte]
Specify the output data in 0 or 1.

Return Value

Ret [ C, C++ : long] [Python: ctypes.c_long]

Definition	Value	Description
CNT_ERR_SUCCESS	0	Normal Complete
CNT_ERR_DLL_INVALID_ID	10001	Invalid ID is specified.
CNT_ERR_DLL_CALL_DRIVER	10002	Driver cannot be called (failed in ioctl).
CNT_ERR_SYS_OUTPUT_DATA	20305	The output data is out of range.

Initial Value

None

Remarks

This function is valid only when the control output signal becomes general-purpose output by setting hardware event. On other mode, it does not operate.

Example

C, C++	Ret = CntOutputDOBit ( Id , 0 , 0 , 1 );
Python	Ret = ccnt.CntOutputDOBit ( Id , 0 , 0 , 1 )
