PI is active in helping standardize wireless networking solutions for industrial applications in both Process and Factory Automation arenas. Across the enterprise, PI specifies WLAN (IEEE802.11.1,b and g) because it is already widely used and because of its simple interfacing with PROFINET.
In Process Automation, PI is one of the primary supporters of the WirelessHART protocol (based on IEEE802.15.4) from the HART Communication Foundation, for connecting to devices and systems. A standard adapter interface for WirelessHART has been agreed by PI in conjunction with other process fieldbus organizations.
A similar initiative to standardize a solution for Factory Automation is now underway based on IEEE802.15 (Bluetooth) as the wireless link and IO-LINK for the field connections.
