CntSetSlave

Function

Sets the specified device to slave. Moreover, sets whether to validate the synchronous control signal.

Format

Ret = CntSetSlave ( Id , ExtSig1 , ExtSig2 , ExtSig3 , MasterHalt , SlaveHalt )

Parameters

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

ExtSig1 , ExtSig2 , ExtSig3 [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
Specify whether to validate the Synchronous signal line.

Value	Description
0	Invalid
1	Valid

MasterHalt [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
1:Fixing(Valid)

SlaveHalt [ VB.NET: Short ] [ C, C++: short ] [ C#: short ] [ Python: ctypes.c_short ]
1:Fixing(Valid)

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_SYS_MEMORY	20000	It failed in memory allocation for the object preparation.
CNT_ERR_SYS_NOT_SUPPORTED	20001	This function can't be used by this device.
CNT_ERR_SYS_USING_OTHER_PROCESS	20003	Cannot use because another process is using the device.
CNT_ERR_SYS_SIGNAL	21003	The available signal is out of range.

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

Initial Value

The default is Stand-alone among Stand-alone/Master/Slave.

Remarks

Must set one of Stand-alone/Master/Slave in order to make the application operation regular. The slave refers to the board on the side that receives the synchronous signal when several boards are synchronously operated with a synchronous control connector (SC connector).

Example

Sets slave mode and don't use synchronous control signal.

VB.NET	Dim Ret As Integer Ret = CntSetSlave ( Id , 0 , 0 , 0 , 1 , 1 )
C, C++	long Ret; Ret = CntSetSlave ( Id , 0 , 0 , 0 , 1 , 1 );
C#	int Ret; Ret = cnt.SetSlave ( Id , 0 , 0 , 0 , 1 , 1 );
Python	Ret = ctypes.c_long() Ret.value = ccnt.CntSetSlave ( Id , 0 , 0 , 0 , 1 , 1 )
