CntGetOperationMode

Function

Retrieves the operation mode (Number of phases, Clear, Multiplier). Supports multi-processing.

Format

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

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.

Phase [ 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 number of phases. Number of phases is returned from the following Definition Value.

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

Mul [ 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 multiplier. Multiplier is returned from the following Definition Value.

Definition	Value	Description
CNT_MUL_X1	0	x1
CNT_MUL_X2	1	x2
CNT_MUL_X4	2	x4

SyncClr [ 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 synchronous clear/asynchronous clear. Clear is returned in the following Definition Value.

Definition	Value	Description
CNT_CLR_ASYNC	0	Asynchronous clear
CNT_CLR_SYNC	1	Synchronous clear

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

2-phase, x1, asynchronous clear

Remarks

Retrieves the operation mode of specified channel.

Example

Retrieves the operation mode of channel 0.
