IDataSourceDriver.State (PROP) ¶ PROPERTY State : DataSourceState
IDataSourceDriver.UpdateRequest (METH) ¶ METHOD UpdateRequest : UDINT This method will be called after a request has been sent to check, whether an answer has arrived. As long as the driver is waiting for a reply, it can return ERR_FAILED. If there was a successful reply it may return ERR_OK, else an Error code describing the error. When ERR_DS_UNKNOWN_TRANSACTION is returned, the server assumes that the transaction is finished and will send new requests.
