2.5 Features of FDAP
The features of FDAP are as follows:
•
DC or Universal AC powered : FDAP operates at DC or AC and provides better latency than battery-based
wireless field device mesh network. It enables the use of wireless field devices for applications requiring fast
update rates (less than 10 seconds) and short latency (less than 250 ms) and in areas where Wi-Fi radios are
not allowed.
NOTE
AC is only supported in FDAP1/FDAP2 models.
•
Antenna diversity : FDAP uses spatial antenna diversity to improve communication success rates and to
improve coverage in multi-path environments. This is necessary for the majority of industrial application
where there is no direct line of site between field devices. Antenna diversity significantly improves data
availability in such applications.
•
Fast Ethernet : FDAP has 10/100 Mbps Fast Ethernet interface and can be integrated into any network that
supports Ethernet communication.
•
Field Mesh network : Multiple FDAPs can form a self-forming, self-healing wireless mesh network. This
extends the range and coverage of the wireless sensor network and provides redundant communication paths
for improved data availability. Unlike battery-power field devices, FDAPs are line powered and so can
aggregate data from multiple field devices including other FDAPs without concerns about battery life.
•
Reduced cost : FDAP reduces wireless field device cost, infrastructure cost, and cost per wireless I/O. It
reduces the number of wireless routing devices and offers wireless coverage for wireless field devices. It
has lesser installation cost than Access Points for sensor only applications.
•
Access points : FDAP acts as a routing access point for wireless field devices and it is designed for sensor-
only network for monitoring application segment.
•
IPv6 device : FDAP is an Internet Protocol version 4 (IPv4) device. The IPv4 protocol provides an end-to-
end data transmission across multiple IP networks. FDAP gets the IP address from DHCP Server in Field
Device Network (FDN). You can ping an FDAP from the FDN network. You cannot ping an FDAP from the
Plant Control Network (PCN). You cannot ping an FDAP when used as a Router.
•
Backbone router : FDAP is a backbone router in a rugged industrial enclosure that acts as a bridge between
the field device network and wireless backhaul network such as IEEE 802.11 WLAN.
