IVisuStreamHandler.StartOperation (METH) ¶ METHOD StartOperation : SysTypes.RTS_IEC_RESULT This method will be called when a read or write operation on the current instance operation is started. The return value can either be: ERR_OK: operation successfully started any other error code: starting an operation is not possible (at the moment) InOut: Scope Name Type Return StartOperation SysTypes.RTS_IEC_RESULT

IVisuStreamHandler.EndOperation (METH) ¶ METHOD EndOperation This method will be called after a read or write operation on the current instance operation is finished or to cancel a not yet finished one. It is assumed that this call always succeeds. InOut: Scope Name Type Comment Input xCancel BOOL This value will be TRUE when the operation should be cancelled and FALSE if the call is only a notification about the end of the operation.
