Method for conducting communications among components of multidomain industrial automation system

摘要

An improved industrial automation system and communication system for implementation therein, and related methods of operation, are described herein. In at least some embodiments, the improved communication system allows communication in the form of messages between modules in different control or enterprise domains. Further, in at least some embodiments, such communications are achieved by providing a communication system including a manufacturing service bus having two internal service busses with a bridge between the internal busses. Also, in at least some embodiments, a methodology of synchronous messaging is employed, where the sending and receiving of a message are governed by ladder logic wherein the message is at least temporarily stored in a buffer after being received, prior to being acted upon by the ladder logic.
