the U.S. Department of Defense to link dissimilar computers across different kinds of
networks. TCP/IP is the transport protocol employed by the Internet and is commonly
used on Ethernet networks.
U

controller's database into the field panel's database so that it can be monitored and
controlled from the field panel.
Unicast: Destination IP address that represents a single interface to a single system. IP
datagrams sent to a unicast address are sent to a single interface on a single IP host.
User Datagram Protocol (UDP): TCP/IP protocol that provides simple datagram
services. UDP is a connection-less mode protocol that is layered on top of IP. UDP
does not guarantee delivery and is not used for applications that require
acknowledgements or re-transmission.

APOGEE Automation Level Network or individual field panels to a P2 Ethernet
