Introduction to FDAP
FDAP description
Note that in this guide, a reference to wireless field devices includes ISA100 Wireless
devices, WirelessHART devices, and Wired HART devices unless otherwise mentioned.
Specific device type is mentioned as and when applicable.
The Field Device Access Point (FDAP) is a ruggedized industrial radio device intended for
use in hazardous locations to provide wireless connectivity for Wireless compatible field
devices. As an industrial meshing access point, FDAP provides secure and reliable wireless
coverage for wireless field devices. It also serves as a routing access point for wireless field
devices and is located between the wired DCS network and wireless field devices. Once
deployed in the field, FDAPs self-discover and self-organize into a managed, secure, and
redundant wireless field device mesh network. With FDAPs, wireless field devices do not
have to route data from other field devices. The following figure illustrates how FDAPs are
used in a OneWireless network.
