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_CLOCK_TRG |
21007 |
The clock condition is out of range. |
The others: (See also: Details of Error Code)
Initial Value
Internal Clock
Remarks
Must set clock condition in order to make the application operation regular. This function should be executed in the setting stage before sampling starts. Set the internal clock value by the function CntSetSamplingInternalClock if Internal Clock is used.
Example
Uses Internal Clock to sampling clock condition.
VB.NET |
Dim Ret As Integer |
C, C++ |
long Ret; |
C# |
int Ret; |
Python |
Ret = ctypes.c_long() |
