wrong IO data buffer when using COS or cyclic

[malotator]

Hello All,

I am using CVI 7.0 for DeviceNet communication with or device...

I have a problem with ReadIO with COS or Cyclic...

It works perfectly when I open a polled IO connection, the data buffer retrieved correspond to my selected assembly...

If I open a COS or Cyclic IO, the Data buffer is giving me random number... If I explicitly read the proper Epath through the Assembly Object, the buffer looks fine...

This is the code that I use to get the proper data

    NCTYPE_UINT8 locServiceCode = 0;
    NCTYPE_UINT8 locServiceData[ 80 ];                                                                                                                            
    NCTYPE_UINT8 * locpServiceDataPointer = locServiceData;                                                                                                         
    NCTYPE_UINT16 locActualServiceDataLength = 0;
    NCTYPE_UINT16 locProduceInstance = 0;    
    

// Read
    if (glConnType == eCOS)
    {
     GetAttributeSingle(GetGlobalDeviceHandle(), eCONNNECTION_ID, 1, 102, &locProduceInstance);
    }
    else
    {
     GetAttributeSingle(GetGlobalDeviceHandle(), eCONNNECTION_ID, 1, 104, &locProduceInstance);
    }

    locActualServiceDataLength = 1;
    locServiceData[0] = 0x03;
    locErrorCode = DoService(GetGlobalDeviceHandle(), 0x0E, eASSY_ID, locProduceInstance, &locActualServiceDataLength, locServiceData, sizeof( locServiceData ), locServiceData );
    memcpy(*locpReadIoDataBuff, locServiceData, locActualServiceDataLength);
    }
