CHAPTER 3 PRODUCT DESCRIPTION
3.1 Wireless Field Interface
The Wireless Field Interface (WFI) adds a wireless capability an existing
servo or the radar gauge supporting the GPU protocol. This wireless
communication is ISA100 compliant. It consists of multiple electronic
boards, an antenna cable, and a communication antenna. The WFI
communicates with the servo or the radar gauge through the Honeywell
Enraf physical layer, processes the data, and forwards the information
wirelessly to the Wireless Device Manager (WDM). The complete
network including the WFI is based on the ISA100 wireless field device
network.
There are different ways of communication which are as follows:
 The protocol tunnel (Engauge and Entis)
 Function blocks (Experion integration)
