Abstract: A relay interface module that is commutatively connectable to at least one I/O device and a controller, wherein the relay interface module is configured to provide data from the I/O device to at least one controller in a distributed control system (DCS) via a communication interface. An application related to a particular I/O device may then be executed freely on any controller present in a DCS without losing real time connection with the associated I/O device. Data can be transferred from an I/O device to an associated application executed on a controller such that the real time connection between the I/O device and the application being executed is maintained.

Abstract: Exemplary embodiments are directed to a method and system of online and dynamic distribution and configuration of applications in a Distributed Control System (DCS) of a plant. One or more applications of at least one controller of the DCS is divided into a plurality of blocks. The application is changed by managing each of the blocks. The one or more blocks is dynamically distributed to at least one other controller of the DCS. The data distributed to the at least one other controller is synchronized between the other controllers. The application associated with the distributed data is managed based on an operation schedule of the DCS.
