IDataServer5.GetRecordResult (METH) ¶ METHOD GetRecordResult : UDINT Returns the result of a record operation. For details <see>StartRecordMode</see>. The result of this operation (if successfull) will be returned in <see>result</see> InOut: Scope Name Type Return GetRecordResult UDINT Output result IDataServerActionRecord

IDataServer5.ReplayRecord (METH) ¶ METHOD ReplayRecord : UDINT Replays a previously recorded UseData/ReleaseData operation Calls to this method must be enclosed in <see>BeginDataConfiguration</see> and <see>EndDataConfiguration</see> InOut: Scope Name Type Return ReplayRecord UDINT Input record IDataServerActionRecord

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!
