Embodiment Construction

[0017] figure 1 An example network 10 is shown in which the wireless protocol adapters described herein may be used. Specifically, the network 10 may include a factory automation network 12 connected to a wireless communication network 14 . Factory automation network 12 may include one or more fixed workstations 16 and one or more portable workstations 18 connected by a communications backbone 20, which may utilize Ethernet, RS-485, Profibus DP, or utilize suitable communications hardware and agreement to implement. These workstations and other devices forming the factory automation network 12 may provide various control and supervisory functions to factory employees, including access to devices in the wireless network 14 . Factory automation network 12 and wireless network 14 may be connected via wireless gateway 22 . More specifically, wireless gateway 22 may be wired or wireless (eg, 802.11g) connected to backbone 20 via first (or "host") interface 23A and may utilize an...

Abstract

A wireless protocol adapter for use in a process system includes a wireless interface that communicates with a multi-node wireless communication network using a wireless communication protocol, a wired interface that connects to a first field device over a wired link, and a processing unit that transfers process data between the wireless communication network and the first field device to enable operation of the first field device and of the wireless protocol adapter in the wireless communication network as distinct network nodes.

Description

technical field [0001] The present invention relates generally to wireless communications in process control environments and, more particularly, to wireless protocol adapters that provide wireless functionality to wired field devices. Background technique [0002] In the process control industry, it is known to use standardized communication protocols to enable devices made by different manufacturers to communicate with each other in a manner that is easy to use and implement. A well-known communication standard used in the process control industry is the High Speed ​​Addressable Remote Transducer (HART) communication base protocol, commonly referred to as protocol. Generally speaking, Protocol supports mixed digital and analog signals on a dedicated wire or wire set where in-line process signals (e.g. control signals, sensor measurements, etc.) as analog current signals (e.g. ranging from 4 to 20 mA) are provided, and other signals such as device data, requests for de...
