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 |

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 master mode is a mode that outputs the signal to a synchronous connector (SC connector). This function should be executed in the setting stage before sampling starts.
Example
Sets the master mode.
VB.NET |
Dim Ret As Integer |
C, C++ |
long Ret; |
C# |
int Ret; |
Python |
Ret = ctypes.c_long() |
