DioDmSetSlaveCfg

Function

Sets the specified device to slave. Sets whether the synchronization control signal is used or not.

Format

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

Parameters

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

ExtSig1 [ C, C++: unsigned long] [Python: ctypes.c_ulong]
ExtSig2 [ C, C++: unsigned long] [Python: ctypes.c_ulong]
ExtSig3 [ C, C++: unsigned long] [Python: ctypes.c_ulong]
Specify whether the synchronization signal line is valid or not.

Value

[Dec]

Description

Invalid

Valid

MasterHalt [ C, C++: unsigned long] [Python: ctypes.c_ulong]
1:Fixed(Valid)

SlaveHalt [ C, C++: unsigned long] [Python: ctypes.c_ulong]
1:Fixed(Valid)

Return Value

Ret [ C, 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.
Slave 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

It enable on ExtSig1, ExtSig2 and ExtSig3.

C, C++

long Ret;

Ret = DioDmSetSlaveCfg(Id, 1, 1, 1, 1, 1);

Python

Ret = ctypes.c_long()

Ret.value = cdio.DioDmSetSlaveCfg(Id, 1, 1, 1, 1, 1)
