This method is used to read an application signal from a script running on a neoVI device.
int _stdcall icsneoScriptReadAppSignal(void * hObject, unsigned int iIndex, double *dValue);Public Declare Function icsneoScriptReadAppSignal Lib “icsneo40.dll” (ByVal hObject As IntPtr, ByVal iIndex As UInt32, ByRef dValue As Double) As Int32[DllImport(“icsneo40.dll”)] public static extern Int32 icsneoScriptReadAppSignal(IntPtr hObject, UInt32 iIndex, ref double dValue);Parameters
hObject
[in] Specifies the driver object created by OpenNeoDevice.
unsigned int iIndex
[in] The index value of the transmit message to read
double *dValue
[in] Contains the current value of the application signal.
Return Values
1 if the function succeeded. 0 if it failed for any reason. must be called to obtain the specific error. The errors that can be generated by this function are:
NEOVI_ERROR_DLL_NEOVI_NO_RESPONSE = 75
NEOVI_ERROR_DLL_SCRIPT_INVALID_APPSIG_INDEX = 225
NEOVI_ERROR_DLL_SCRIPT_NO_SCRIPT_RUNNING = 226
Remarks
The script containing the specified application signal must have been successfully downloaded to the neoVI using . The script must also have been started using . This function will fail if has been called. The valid index values for application signals within a script can be found in the cmvspy.vs3cmb.h file that is produced by Vehicle Spy. Please see Vehicle Spy documentation.
