AI Technical Summary

Problems solved by technology

This additional load can make the process controller less effective, or it can cause lost or slow communications with specific field devices, as the process controller needs to prioritize which communications are necessary or desired in any particular situation
Additionally, this situation makes field devices much less effective in supporting multiple uses

Embodiment Construction

[0046] now refer to figure 1 , generally shows a highly versatile (HV) field device 10 in block diagram form. In particular, highly versatile field device 10 includes field device hardware 12, which may be, for example, one or more sensors, actuators, valve seats and stems, or any other typical or desired control associated with the operation of the field device hardware. Control hardware 12 may be any combination of hardware typically associated with any type of control device, such as sensors (e.g., temperature sensors, flow meters, liquid level sensors, pressure sensors, etc.), valves, or other flowing gas or Liquid flow control structures, igniters, fans, motors, actuators, pumps, etc. Control hardware 12 may be, for example, a control structure that measures or senses, or controls or affects, one or more physical phenomena in a factory or manufacturing plant setting, and may be compatible with any Any control hardware associated with known control field devices.

Abstract

A method and system for a publication-subscription communication architecture for a highly universal (HV) field device in a control and automation system enables receiving, at the HV field device, a message from a client device or application indicating a selection of one of a plurality of publication categories. The publication category corresponds to a type of information desired by the client device or application. The field device transmits an identification of each of a plurality of publication lists corresponding to the selected publication category to the client device or application, each of the plurality of publication lists being stored on the field device and each including a set of parameters associated with the field device. The field device receives a selection of one of the publication lists identified by the field device from the client device or application, and transmits a parameter set associated with the selected publication list to the client device or application.

Description

technical field [0001] This application relates generally to process control and factory automation systems, and in particular to enhanced field devices for use in these systems, capable of performing a variety of different functions simultaneously in different contexts, and capable of using one or more Different communication protocols communicate with different or separate client devices or applications. Background technique [0002] Distributed process control systems, such as those used in chemical, petroleum, industrial, or other process plants to manufacture, refine, convert, generate, or produce physical materials or products, typically include one or more process Controllers that are communicatively coupled to one or more field devices via a physical layer, which may be an analog, digital, or combined analog / digital bus, or may include one or more wireless communication links or networks. Field devices, such as valves, valve positioners, switches, and transmitters (...
