Systems and methods 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.

主权项

1. A method of communicating between a control-level module and an enterprise-level module, the method comprising:
receiving a first message in accordance with a first protocol from the control-level module at a receive manager of a bridge device, wherein the first protocol is an industrial protocol; sending a second message from the bridge device back to the control-level module when the bridge device has determined that the first message has been successfully received; analyzing the first message at a transaction manager of the bridge device so as to determine an adapter suitable for enabling further communication of the first message to the enterprise-level module; encoding, by the bridge device, a message header based at least in part upon the first message; and communicating a third message based upon the first message for receipt by the enterprise-level module through the use of the adapter, wherein the communicating of the third message occurs in accordance with a second protocol that is an information technology based or information technology oriented protocol, wherein the bridge device is a business message manager implemented on a server that either supports or communicates with the enterprise-level module, and wherein the first message is received via a network employing the industrial protocol, and wherein the industrial protocol employed by the network is a common industrial protocol (CIP) such that the network is a CIP-based network, and wherein the first message received via the CIP-based network is communicated via a class-3 connection.
