General - Product Introduction

CHAPTER 1 GENERAL

1.1 Product Introduction

The Wireless Field Interface (WFI) adds a wireless capability to the existing servo or the radar gauge by supporting the GPU protocol which is compliant with the ISA100 standards. It consists of multiple electronic boards, an antenna cable, and an antenna. The WFI communicates with the servo or the radar gauge through the Honeywell Enraf field bus Bi-Phase Mark, processes the data, and forwards the information wirelessly to the Wireless Device Manager (WDM) which is compliant with the ISA100 standards. The complete network including the WFI is based on the ISA100 wireless field device network.
Also, there are different ways of communication which are as follows:
The protocol tunnel (Engauge and Entis)
Function blocks (Experion integration)

3.1 Introduction

3.2 System Architecture

The WFI is a box that can be installed next to an installed Servo/Radar gauge. The WFI retrieves the information from this gauge and sends the information wirelessly to the supervisory level.
This is an ISA100 compliant solution that supports transducer blocks for transferring basic process values to the supervisory level and supports the GPU tunnel to connect to the Engauge (maintenance) and Entis (inventory management package) systems. See FIGURE 3-1.
