Generation and publication of shared label sets

Abstract

This application provides for the generation and publication of shared tag sets. Provided is a system and method that facilitates receiving tag requests from one or more interfaces based on compiling at a controller a single tag set that includes all requested tags for a given update rate, so that a single compiled tag Sets are then forwarded to one or more interfaces. The controller generates a superset of tags associated with industrial processes. Each interface may request a copy from which to select a superset of required labels. The controller receives requested tags from all interfaces for a given update rate and combines the requested tags into a single tag set that includes various parameters associated with the tags. At the selected update rate, the tag set is forwarded to the interface. The main set can be used to identify the sequence of tags in the tag set, and the checksum can ensure the continuity of the tags in the tag set.

Description

technical field [0001] The present specification relates generally to control systems employed in an industrial automation environment, and more particularly to generating and publishing a set of tags to at least one interface associated with a controller. Background technique [0002] Computer systems, like other operating environments, are heavily used in industrial automation environments and are widely used, for example, to control the operation of devices, machines, processes, and the like. To facilitate controlling a process, etc., utilize one or more controllers along with I / O devices that control the operation of the process as well as collect process information (e.g., measurements, data, values, parameters, variables, metadata, etc.) related to how the process is performed . To maximize operator interaction with the process, process information may be forwarded from the controller to one or more interfaces, also known as human-machine interface (HMI), graphical us...

AI Technical Summary

Problems solved by technology

[0003] However, in conventional systems, various parameters, measurements, data, values, variables, metadata, etc. including process information need to be generated for each interface of the monitoring process, regardless of whether any interface is receiving or displaying on another interface processing information

This generation of unique data packets in response to each process information data "pull" request generated by each interface monitoring the process is inefficient and places an unnecessary operational burden on the controller associated with the process

[0004] The above-mentioned deficiencies of traditional interface-controller systems are only intended to provide an overview of some of the problems with traditional systems and techniques, and are not exhaustive
