CntSetOperationMode

Function

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

Format

Ret = CntSetOperationMode ( 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 setting.

Phase [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify the number of phases. Number of phases is selected 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#: short ] [ Python: ctypes.c_short ]
Specify the multiplier. Multiplier is selected from the following Definition Value.

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

SyncClr [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify Synchronous clear/Asynchronous clear. Select from 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_MODE	10100	Invalid mode setting.
CNT_ERR_SYS_BOARD_EXECUTING	20002	Cannot use while by another device works.
CNT_ERR_SYS_MODE	20100	Invalid mode setting.
CNT_ERR_SYS_CH_NO	20201	Channel number is out of range.

Initial Value

2-phase, 1x, Asynchronous clear

CPSN-CNT-3201I2

When used in combination with CPSN-MCB271, the initial value immediately after power-on depend on the settings configured via the web browser.

Remarks

Specifies the mode of specified channel. This function becomes valid when the counter stared.

"Synchronous clear" or "Asynchronous clear" on SyncClr are followed Z-phase signal.
It isn't occurred Error even though calling CntSetOperationMode function when you set CNT_ZPHASE_NOT_USE by CntSetZMode function.

The internal logic level of SyncClr is hold. All held settings are reflected to the device when the counter is stared.
Therefore, when the Z-phase setting is changed in CntSetZMode from CNT_ZPHASE_NOT_USE to either CNT_ZPHASE_NEXT_ONE or CNT_ZPHASE_EVERY_TIME the "Synchronous clear" or "Asynchronous clear" configured earlier in CntSetOperationMode will be executed before the counter starts.

Example

Sets 1-phase, 1x, Asynchronous clear to the operation mode of channel 0.

VB.NET	Dim Ret As Integer Ret = CntSetOperationMode ( Id , 0 , CNT_MODE_1PHASE , CNT_MUL_X1 , CNT_CLR_ASYNC )
C, C++	long Ret; Ret = CntSetOperationMode ( Id , 0 , CNT_MODE_1PHASE , CNT_MUL_X1 , CNT_CLR_ASYNC );
C#	int Ret; Ret = cnt.SetOperationMode ( Id , 0 , (short)CcntConst.CNT_MODE_1PHASE , (short)CcntConst.CNT_MUL_X1 , (short)CcntConst.CNT_CLR_ASYNC );
Python	Ret = ctypes.c_long() Ret.value = ccnt.CntSetOperationMode ( Id , 0 , ccnt.CNT_MODE_1PHASE , ccnt.CNT_MUL_X1 , ccnt.CNT_CLR_ASYNC )
