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
