CntGetZLogic

Function

Retrieves the Z-phase logic (Positive Logic/Negative Logic). Supports multi-processing.

Format

Ret = CntGetZLogic ( Id , ChNo , ZLogic )

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 retrieving.

ZLogic [ VB.NET: Short ] [ C, C++: short * ] [ C#: out short ] [ Python: ctypes.POINTER(ctypes.c_short) ]
Specify the address of the variable that stores the retrieved Z-phase logic. Z-phase logic is returned from the following definition value.

Definition	Value	Description
CNT_ZLOGIC_POSITIVE	0	Positive Logic
CNT_ZLOGIC_NEGATIVE	1	Negative Logic

Return Value

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

Definition	Value	Description
CNT_ERR_SUCCESS	0	Normality completion
CNT_ERR_SYS_RECOVERED_FROM_STANDBY	7	Execute the function CntResetDevice to return from the standby mode.
CNT_ERR_DLL_INVALID_ID	10001	Invalid ID was specified.
CNT_ERR_DLL_CALL_DRIVER	10002	CNT driver can't be called (Failed in the device I/O control).
CNT_ERR_DLL_BUFF_ADDRESS	10101	Invalid data buffer address.
CNT_ERR_SYS_BOARD_EXECUTING	20002	Cannot use while by another device works.
CNT_ERR_SYS_CH_NO	20201	Channel number is out of range.

The others: (See also: Details of Error Code)

Initial Value

Negative Logic

Remarks

Retrieves the Z-phase logic of specified channel.

Example

Retrieves the Z-phase logic of channel 0.

VB.NET	Dim Ret As Integer Dim ZLogic As Short Ret = CntGetZLogic ( Id , 0 , ZLogic )
C, C++	long Ret; short ZLogic; Ret = CntGetZLogic ( Id , 0 , &ZLogic );
C#	int Ret; short ZLogic; Ret = cnt.GetZLogic ( Id , 0 , out ZLogic );
Python	Ret = ctypes.c_long() ZLogic = ctypes.c_short() Ret.value = ccnt.CntGetZLogic ( Id , 0 , ctypes.byref(ZLogic) )
