SYSTEM AND METHOD FOR DISSEMINATING FUNCTIONAL BLOCKS TO AN ON-LINE REDUNDANT CONTROLLER

摘要

A system for, and method of, disseminating a functional block to a redundant controller for a real-time process control system and a real-time process control system incorporating the system or the method. In one embodiment, the system includes: (1) a dynamically linkable library object associated with the functional block and (2) a shared memory, associated with at least two nodes of the redundant controller, that receives the dynamically linkable library object and the functional block and provides concurrent access thereto by both the at least two nodes to ensure consistent memory images therefor without requiring one of the at least two nodes to be taken off-line.
