Overview

Field Expandable Wireless IO (FEWIO) is an innovative solution aimed to provide a method for integrating
legacy Modbus devices into OneWireless system. Honeywell Field Device Access Point (FDAP) is configured in
way wherein it can be used as an expandable wireless device that extracts the data from the legacy Modbus
devices, wirelessly. This is a licensed feature.
Typically, in a plant there are thousands of legacy wired Modbus devices and managing (monitoring, viewing,
accessing data) them is a mammoth task. To wirelessly enable this, you can use the FEWIO solution. This
solution will give huge cost savings (no wiring, switches will be needed) and will make the data easily
accessible.
You can connect multiple Modbus devices to OneWireless Network using the Honeywell Field Device Access
Point (FDAP). FDAP will change its role to FEWIO and extracts the data from Modbus (RTU/TCP) slave
devices and converts it to the ISA100 environment. The legacy devices are connected to the FDAP using the RS-
485 protocol or TCP/IP. The collected data in WDM can be accessed by a SCADA or any other third party
applications.
Only FDAP acting as a field router can be converted to FEWIO.
