RequestData (STRUCT) ¶ TYPE RequestData : STRUCT InOut: Name Type Comment dwTransactionId DWORD xIgnoreResult BOOL Indicates, whether the result of the request has to be evaluated (FALSE) or can be ignored (TRUE). This flag is necessary, because method UpdateRequest is called both from the monitoring and the request to write variables bFinished BOOL bAdditionalChannel BOOL eReplyState PlcConnectionState The required state the reply must have after the request has been sent. This will be used to determine later whether the reply is available.
