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.
