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: A programmable logic controller for an industrial control system is disclosed which includes an application logic execution layer and at least one of an update checking layer and an output checking layer. The application logic layer is configured for processing sensor input data to generate an output parameter for an actuator. The output checking layer is configured for outputting only an allowed output parameter to the actuator. The update checking layer is configured for verifying whether application logic update defined by application logic update data corresponds to an application logic update in a list of allowed logic updates, and the application logic is updated only if the update data is allowed application logic update data.
