Honeywell OneWireless™ Field Device Access Point (FDAP) is an industrial meshing access point for ISA100™ Wireless (IEC 62734) and WirelessHART (IEC 62591) field instruments and rated for use in hazardous plant environments. It uses Honeywell’s intelligent wireless algorithms combination to extend the wireless coverage of field instruments by a factor of 1.5, thereby minimizing the infrastructure required
What Is It?
Once implemented, the FDAP auto-discovers neighboring wireless devices such as other access points and ISA100 Wireless and WirelessHART field instruments to form a secure IEEE 802.15.4 mesh network. The device supports all ISA100 Wireless and WirelessHART field instruments, including wired HART field instruments connected with wireless adapters.
The FDAP enables users to implement wireless field instruments in harsh multi-path indoor and outdoor environment since its antenna diversity enhances communication reliability in such environments. In addition, it enables use of wireless field instruments for critical monitoring or open loop control in hazardous environments (Class 1 Div 1/Zone 1) that require update rates of less than 10 seconds.
