摘要： The invention relates to a method of online and dynamic schedule configuration of control applications in a Distributed Control System (DCS). The invention considers having a DCS with a plurality of controllers, where controllers include one or more of source controllers and one or more of destination controllers. The method of the invention comprises the steps of: a) selecting one or more blocks of control applications in an optimal manner. Such blocks of control applications in one or more source controllers can be migrated across one or more destination controllers; b) identifying one or more potential slots for executing blocks in one or more destination controllers. These potential slots are employed for accommodating the said selected one or more blocks of control applications accordingly; c) publishing the information pertaining to one or more of the said identified potential slots to a central management entity or to corresponding one or more said source controllers by the one or more destination controllers; d) determining said one or more potential slots and its corresponding said selected block thereto for each of the said destination controller accordingly by the central management entity or by the said one or more source controller; and e) proposing schedule configuration of control applications by the said central management entity or by the said one or more source controller; and f) performing schedulability analysis for each of the said one or more blocks or of its logical combination thereof. The invention also relate to a system for performing online and dynamic schedule configuration of control applications in a Distributed Control System (DCS) having a plurality of controllers, in accordance with the method of the invention.
