IDataServer5.ResumeAfterTempShutdown (METH) ¶ METHOD ResumeAfterTempShutdown : UDINT This method can be called to resume the normal operation of a datasource after a call to <see>StartTempShutdown</see> Calls to this method must be protected by calling BeginDataConfiguration/EndDataConfiguration around this call. InOut: Scope Name Type Comment Return ResumeAfterTempShutdown UDINT Input pstDataSource POINTER TO STRING The name of the datasource, must not be NULL
IDataServer5.StartRecordMode (METH) ¶ METHOD StartRecordMode : UDINT Clients of the dataserver can call this method to start recording the following actions (UseData, ReleaseData). In between calls to this method and the according call to <see>GetRecordResult</see> no real action will be done. Instead the action will only be recorded. The result can be retrieved using <see>GetRecordResult</see>. InOut: Scope Name Type Return StartRecordMode UDINT
IDataServer5.StartTempShutdown (METH) ¶ METHOD StartTempShutdown : UDINT This method can be used for temporarily shutting down a dataserver connection. Due to the reason that this shutdown might take some cycles, the user of this method should wait until the operation is finished. This can be determined using the callback <see>cbShutdownDone</see>. Calls to this method must be protected by calling BeginDataConfiguration/EndDataConfiguration around this call. To resume the normal operation of the datasource call the method <see>ResumeAfterTempShutdown</see>. InOut: Scope Name Type Comment Return StartTempShutdown UDINT Input pstDataSource POINTER TO STRING The name of the datasource, must not be NULL cbShutdownDone ICallback An optional callback that will be triggered when the shutdown is finished. The callback parameter will be a pointer to a <see>ITempShutdownResult</see>. Please remember that the callback might be called from a different task then the call to <see>StartTempShutdown</see>. Please remember that the given object must live at least until the callback is called. Don’t pass a function local variable for this parameter!

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.
