Next Generation Controller Specification for an Open Systems ArchitectureStandard

摘要

This report describes an open architecture framework for advanced manufacturingcontrollers including machine tools, robotics, process control and coordinate measurement. The methodology described is applicable to both system design as well as system retrofit applications. A component-based approach is used that allows system architectures to the developed from generic building blocks that address system requirements and resulting functionality requirements. Initial architectures are used to produce an application architecture that addresses specific system messaging requirement. An application system is then synthesized using off-the-shelf, reusable implementation components for the application software. Hardware-software specific platform issues are addressed through the USC of system profiles,a convention adopted form the IEEE Portable Operating system Interface (POSIX) standard that is now gaining wide acceptance. A number of examples are provided demonstrating use of all aspects of the methodology on a typical machine tool controller application. Appendices provide details with respect to specific components, requirements, and domiain models.
