Optimized communications with HART instruments

Abstract

A device, such as a HART multiplexer, may allow access to one or more HART instruments from a single interface. The device may also support access to the HART instruments from a second interface. Requests for reading or writing data to or from a HART instrument may be combined at the device into a set of HART commands that may be more efficient than the HART commands that would be sent if each request was processed independently.

Background technique [0003] Devices connected to an industrial network, such as a network with devices for automation control or some other process control type, may use various protocols to communicate with each other. Any one communication protocol may allow access to certain data throughout the network, but may not allow access to other data or devices. Additionally, translating data requests from one protocol to another may cause ine...
