DioDmSetMasterCfg

Function

Sets the specified device as a master. Also, sets the contents to be output as the synchronization signal.

Format

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

Parameters

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

ExtSig1 [C:unsigned long] [Python: ctypes.c_ulong]
ExtSig2 [C:unsigned long] [Python: ctypes.c_ulong]
ExtSig3 [C:unsigned long] [Python: ctypes.c_ulong]
Specify signals output to the signal lines from ExtSig1 to ExtSig3.

Return Value

Ret [C:long] [Python: ctypes.c_long]

Definition	Value [Dec]	Description
DIO_ERR_SUCCESS	0	Normal complete
DIO_ERR_DLL_INVALID_ID	10001	Invalid ID is specified.
DIO_ERR_DLL_CALL_DRIVER	10002	Driver cannot be called (failed in ioctl).
DIO_ERR_SYS_SIGNAL	50001	Outside the range of the signal.

The other errors: (See also: Error code details)

Initial Value

Stand-alone should be specified from the choice of Stand-Alone, Master, or Slave.

Remarks

One of the settings must be executed from Stand-Alone, Master, or Slave to fix the application operation.
Master indicates the board where the synchronization signal is output in the case of operating a number of boards in synchronization using a synchronization control connector (SC connector).

Example

C	Ret = DioDmSetMasterCfg( Id, DIODM_EXT_START_SOFT_IN, DIODM_EXT_CLOCK_IN, DIODM_EXT_STOP_SOFT_IN, 1, 1 );
Python	Ret = cdio.DioDmSetMasterCfg( Id, cdio.DIODM_EXT_START_SOFT_IN, cdio.DIODM_EXT_CLOCK_IN, cdio.DIODM_EXT_STOP_SOFT_IN, 1, 1 )
