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 associable 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 therefore without requiring one of the at least two nodes to be taken off-line.

System and method for disseminating functional blocks to an on-line redundant controller

For use within a computer-based digital control system, a calling mechanism and method for allowing both dynamic linked application objects and static linked application objects created with heterogeneous development tool sets to interact with a kernel of the system or with each other. In one embodiment, the calling mechanism includes: (1) a dynamic link interface that employs only standards-based software calls to allow the dynamic linked application objects to interact with the kernel, (2) a static link interface that employs at least one non-standard software call to allow the static link application objects to interact with the kernel and (3) at least one call router, operative to manage software calls among the kernel, the dynamic link application objects and the static link application objects, that detects software call types and routes the software calls to a selected one of the dynamic link interface or the static link interface based on the software call types.
