RootAddressDatasourceIndex.DatasourceIndex (PROP) ¶ PROPERTY DatasourceIndex : INT

RootAddressDatasourceIndex.QueryInterface (METH) ¶ METHOD QueryInterface : POINTER TO POINTER TO BYTE InOut: Scope Name Type Comment Return QueryInterface POINTER TO POINTER TO BYTE Input iid DWORD InterfaceID pResult POINTER TO UDINT

StateMachine.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, CmpErrors.Errors.ERR_PENDING should be returned. When it finished successfully, CmpErrors.Errors.ERR_OK should be returned. When connecting failed, an error code should be returned and then the whole connection will be set up again.

StateMachine.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, CmpErrors.Errors.ERR_PENDING should be returned. When it finished successfully, CmpErrors.Errors.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 IDatasources.IDriverRequest The request object to check for it’s result

StateMachine.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.
