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

A highly versatile process control or plant automation field device is configured with an interface and communication connection structure that enables the field device to operate as a data server that simultaneously performs standard process and plant automation control functions. The system directly or indirectly communicates with and supports a plurality of different applications or clients. Furthermore, a variety of different process control and plant automation network architectures, in particular communication architectures, support a universal field device to enable the universal field device to use the same or different communication protocols, via a public communication network infrastructure, communication with a plurality of different client devices or applications (each associated with a different system) is performed simultaneously.
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 (...
