CntOutputDOBit


Function

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

Format

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

Parameters

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

ChNo [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify the channel number for setting.

Reserved [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify 0.

OutData [ VB.NET: Byte ] [ C, C++: BYTE ] [ C#: byte ] [ Python: ctypes.c_ubyte ]
Specify the output data in 0 or 1.

Return Value

Ret [ VB.NET: Integer ] [ C, C++: long ] [ C#: int ] [ Python: ctypes.c_long ]

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

Sets 1 to general-purpose output to channel 0.

VB.NET

Dim Ret As Integer
Ret = CntOutputDOBit ( Id , 0 , 0 , 1 )
 

C, C++

long Ret;
Ret = CntOutputDOBit ( Id , 0 , 0 , 1 );
 

C#

int Ret;
Ret = cnt.OutputDOBit ( Id , 0 , 0 , 1 );
 

Python

Ret = ctypes.c_long()
Ret.value = ccnt.CntOutputDOBit ( Id , 0 , 0 , 1 )
