IDataServer.AllItemsOk (METH) ¶ METHOD AllItemsOk : UDINT This method will return ERR_OK when all active items of all datasources have the quality good else it will return ERR_DS_BADITEMS. It might return ERR_DS_MULTITASKING_LOCKED when it is currently not possible to have access to all datasources. In this case the client should call this method again later. InOut: Scope Name Type Return AllItemsOk UDINT
