CntGetOperationMode

Function

Gets the operation mode. (Number of phases, Clear, Multiplier)

Format

Ret = CntGetOperationMode ( Id , ChNo , Phase , Mul , SyncClr )

Parameters

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

ChNo [ C: short ] [ Python: ctypes.c_short ]
Specifies the channel number which you want to get for.

Phase [ C: short * ] [ Python: ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the variable that stores the number of phases. As for the number of phases, one of the following defined values is returned.

Definition	Value	Description
CNT_MODE_1PHASE	0	Mono-phase
CNT_MODE_2PHASE	1	2-phase
CNT_MODE_GATECONTROL	2	Gate control

Mul [ C: short * ] [ Python: ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the variable that stores the multiplier. As for multiplier, one of the following defined values is returned.

Definition	Value	Description
CNT_MUL_X1	0	1X
CNT_MUL_X2	1	2X
CNT_MUL_X4	2	4X

SyncClr [ C: short * ] [ Python: ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the variable that stores synch clear/async clear As for clear, either of the following defined values is returned.

Definition	Value	Description
CNT_CLR_ASYNC	0	Async clear
CNT_CLR_SYNC	1	Synch clear

Return Value

Ret [ 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_CH_NO	20201	Channel number is outside the range.

The other errors: (See also: Details of Error Code)

Initial Value

2-phase, 1X, Async clear

Remarks

Gets the mode for the specified channel.

Example

C	Ret = CntGetOperationMode(Id, ChNo, &Phase, &Mul, &SyncClr);
Python	Ret = ccnt.CntGetOperationMode(Id, ChNo, ctypes.byref(Phase), ctypes.byref(Mul), ctypes.byref(SyncClr))
