IDriverRequestFactoryReusable.ReusableRequestsSupported (PROP) ¶ PROPERTY ReusableRequestsSupported : BOOL This property returns whether reusable requests are supported. Note If a driver in general supports those requests but not using the current device for example, then this property can return FALSE.
IDriverRequestReusable (ITF) ¶ INTERFACE IDriverRequestReusable EXTENDS IDriverRequest Implementations of this interface represent requests that can be used several times and can be used for both reading or writing. Properties: NextOperation Structure: NextOperation (Property)
IDriverRequestReusable.NextOperation (PROP) ¶ PROPERTY NextOperation : ReusableRequestOperations Gets or sets the operation that will be executed when the request is sent the next time.
IDriverSpecificData (ITF) ¶ INTERFACE IDriverSpecificData EXTENDS __SYSTEM.IQueryInterface A derived interface of this one can be used by drivers to attach information to instances of IDataItemBase Methods: Release Structure: Release (Method)
IDriver.CredentialsHandling (PROP) ¶ PROPERTY CredentialsHandling : IDriverCredentialsHandling If this kind of driver requires credentials for logging in to a specific kind of device, then this property can return an object handling the assignment of credentials.
IDriver.DataByteOrder (PROP) ¶ PROPERTY DataByteOrder : ByteOrder Returns the byteorder of value data managed by this instance. Note It is not expected that this value changes at runtime. Important Please remark that this value does not give information about the byte order used by the connected device but merely returns the information about the byteorder of data managed by IDataItemValueAssigner .
IDriver.Init (METH) ¶ METHOD Init This method passes an instance of the configuration object to the driver. The according concrete type is driver dependent and the codegeneration will allocate and initialize the configuration object accordingly before calling this method. InOut: Scope Name Type Comment Input pCFGData POINTER TO BYTE A pointer to the configuration data. This pointer can be casted to the conrete implementing type. It’s the responsibility of the drivers Automation Platform implementation to assure the correct type.
IDriver.RequestFactory (PROP) ¶ PROPERTY RequestFactory : IDriverRequestFactory
IDriver.StateMachine (PROP) ¶ PROPERTY StateMachine : IDriverStateMachine
IDriver.TargetByteOrder (PROP) ¶ PROPERTY TargetByteOrder : ByteOrder Returns the byteorder used by the system managed by the related IDatasource . Note It is not expected that this value changes at runtime.
