Wireless process control has been a popular topic recently in the field of industrial control. In the industrial field, wireless technologies are considered despite the lack of an ideal industrial wireless standard. However, application development of industrial wireless networks is slow due to the lack of an ideal standard. Open standards are the foundation of industrial wireless application extensions. This paper first summarizes a standardized process for industrial wireless network technologies and then introduces network composition, network topology, protocol stack architecture, and some key protocol technologies of WIA-PA, which is an international specification of industrial wireless networks for process automation. Furthermore, a comparison between WIA-PA and other main industrial wireless network specifications like WirelessHART and ISA100.11a is provided. Architecture and key technologies of a WIA-PA are also introduced. Our first-hand experiences in developing WIA-PA testbed based on the modularization method are given. Finally, experiment results illustrate the performance and efficiency of WIA-PA. Copyright © 2010 John Wiley & Sons, Ltd.
