DioDmSetSlave


Function

Sets the specified device to slave. And sets whether use the synchronous control signal.

Format

Ret = DioDmSetSlave ( 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 DioInit.

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

Description

DIO_ERR_SUCCESS

0

Normal completed.

DIO_ERR_SYS_RECOVERED_FROM_STANDBY

7

Execute DioResetDevice function because the device has recovered from standby mode.

DIO_ERR_DLL_INVALID_ID

10001

Invalid ID specified.

DIO_ERR_DLL_CALL_DRIVER

10002

Not call the driver (Failure on DEVICE I/O CONTROL).

DIO_ERR_SYS_NOT_SUPPORTED

20001

This board couldn't use this function.

DIO_ERR_SYS_SIGNAL

21000

Signal is outside the setting range.

The others (See also: Details of Error Code)

Initial Value

The default is stand-alone among stand-alone, master and slave.

Remarks

It is necessary to set the device to one mode among stand-alone, master and slave to make the application operation regular.

The slave is used in this case, when two or more boards are synchronously operated with a synchronous control connector (SC connector), the board that receives the synchronously signal is specified to slave.

Example

VB.NET

Dim Ret As Integer
Ret = DioDmSetSlave ( Id , 1 , 1 , 1 , 1 , 1 )
 

C, C++

long Ret;
Ret = DioDmSetSlave ( Id , 1 , 1 , 1 , 1 , 1 );
 

C#
 

int Ret;
Ret = dio.DmSetSlave ( Id , 1 , 1 , 1 , 1 , 1 );
 

Python

Ret = ctypes.c_long()
Ret.value = cdio.DioDmSetSlave ( Id , 1 , 1 , 1 , 1 , 1 )
