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 (20A,...,20D;18A,...,18E) 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 (28;30) with a bridge (32) between the internal busses. Also, in at least some embodiments, a methodology of synchronous messaging is employed.
摘要:
Systems and methods that vary multiple data sampling rates, to collect sets of data with different levels of granularity for an industrial system. The data for such industrial system includes sets of data from the "internal" data stream(s) ( e . g ., history data collected from an industrial unit) and sets of data from an "external" ( e . g ., traffic data on network services) data stream(s), based in part on the criticality/importance criteria assigned to each collection stage. Each set of data can be assigned its own unique data collection rate. For example, a higher sample rate can be employed when collecting data from the network during an operation stage that is deemed more critical ( e . g ., dynamic attribution of predetermined importance factors) than the rest of the operation.

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.
