IDriverSpecifiedSettingsReadOnChange.ReadOnChangeOnly (PROP) ¶ PROPERTY ReadOnChangeOnly : BOOL Return TRUE when the according implementation does not do cyclic updates of variables but instead executes read requests only triggered by changes of according variables on the connected device. Note This value is not intended to change without a new download.

IDriverStateMachine (ITF) ¶ INTERFACE IDriverStateMachine EXTENDS __SYSTEM.IQueryInterface Properties: ShutdownAfterError Methods: Connecting PollRequestResult ResetAfterError SendRequest ShuttingDown StartConnect StartShutdown Structure: Connecting (Method) PollRequestResult (Method) ResetAfterError (Method) SendRequest (Method) ShutdownAfterError (Property) ShuttingDown (Method) StartConnect (Method) StartShutdown (Method)

IDriverStateMachine.Connecting (METH) ¶ METHOD Connecting : SysTypes.RTS_IEC_RESULT Using this method the driver is polled whether the startup of the connection is already finshed. InOut: Scope Name Type Comment Return Connecting SysTypes.RTS_IEC_RESULT An error code representing the result of the polling operation. In case the operation is not yet finished, ERR_PENDING should be returned. When it finished successfully, ERR_OK should be returned. When connecting failed, an error code should be returned and then the whole connection will be set up again.

IDriverStateMachine.PollRequestResult (METH) ¶ METHOD PollRequestResult : SysTypes.RTS_IEC_RESULT Using this method the driver is polled whether the given request is already finshed. InOut: Scope Name Type Comment Return PollRequestResult SysTypes.RTS_IEC_RESULT An error code representing the result of the polling operation. In case the operation is not yet finished, ERR_PENDING should be returned. When it finished successfully, ERR_OK should be returned. When sending a request failed, an error code should be returned and then the whole connection will be set up again. Input request IDriverRequest The request object to check for it’s result

IDriverStateMachine.ResetAfterError (METH) ¶ METHOD ResetAfterError This method is called after a failed call to one of the other methods where IDriverStateMachine.ShutdownAfterError returns FALSE. Implementations can use this call to get into a state where it is possible to start a new connection after some delay.

IDriverStateMachine.SendRequest (METH) ¶ METHOD SendRequest : SysTypes.RTS_IEC_RESULT Using this method a request should be sent by the driver. InOut: Scope Name Type Comment Return SendRequest SysTypes.RTS_IEC_RESULT An error code representing the result of the polling operation. In case the operation is not yet finished, ERR_PENDING should be returned. This will then cause followup calls to IDriverStateMachine.PollRequestResult . In case the operation finished synchronously, ERR_OK should be returned. When sending a request failed, an error code should be returned and then the whole connection will be set up again. Input request IDriverRequest The request object representing the information that should be sent to the connected device.

ICustomRequestCallback (ITF) ¶ INTERFACE ICustomRequestCallback EXTENDS __SYSTEM.IQueryInterface Methods: RequestFinished Structure: RequestFinished (Method)

ICustomRequestCallback.RequestFinished (METH) ¶ METHOD RequestFinished This method will be called when the execution of the given request is finished. Note The method will be called no matter whether the request was executed successfully or not. Callees can find out about this fact by evaluating the according result. InOut: Scope Name Type Comment Input request ICustomRequest The request that was finished response ICustomResponse The response to the request. Valid only in case the result is ERR_OK. Note Please remark that this object is no longer valid when this method returns. result SysTypes.RTS_IEC_RESULT The result of the execution as one of the runtime system error codes (see CmpErrors.library) or one of Errors . In case the service was sent successfully, ERR_OK will be set as the result
