D
Device ID: Uniquely identifies a device object on the BACnet Inter network.
Device Instance Number: A number assigned to a BACnet device (for example, a
BACnet field panel) that uniquely identifies it on the BACnet/IP network.
Device port: A USB Device port supports a generic serial interface for an HMI or Tool
connection.
Device Specific Name: A textual representation of a BACnet object name that meets
the APOGEE naming standard of 30 alphanumeric characters or less.
digitized value: Integer value used by the field panel to determine the logical value,
state, and condition of logical points.
Domain Name Server (DNS): Common method of assigning computer names in UNIX-
based networks. A DNS server maintains a list of host names and IP addresses,
allowing computers that query them to find remote computers by specifying host
names rather than IP addresses. DNS is a distributed database; therefore, DNS
servers can be configured to use a sequence of name servers, based on the domain in
the name being looked for.
Dynamic Host Configuration Protocol (DHCP): Protocol used for automatic TCP/IP
configuration of nodes across a network. DHCP dynamically assigns addresses to
nodes and allows for central administration of addresses.
dynamic point information: Information stored in the point database that may change
during system operation and is not part of the data entered when defining points.
E
enclosure: Metal case that houses the field panel components.
English units: The foot-pound-second system of units for weights and measurements.
enhanced alarming: Application that allows floating alarms and alarm segregation.
Ethernet ready: Any device that communicates over Ethernet cabling. For example,
both Ethernet ALN and BACnet/IP field panels are Ethernet ready, even though they
use different communication protocols.
F
Field Level Network (FLN): A data communications link that passes information
between an FLN device and an Automation Level Network (ALN) device. The terminal
Equipment Controller (TEC) is an example of an FLN device.
H
HAND-OFF-AUTO (HOA) switches: Manually operated control switches located on the
face of HOA-equipped controllers that enable digital output points to be manually
placed into HAND (ON), OFF, or AUTO control. Analog outputs can be placed into
AUTO or multiple manual control positions.
Host port: A USB Host port provides support for USB modems and line printers.
Human-Machine Interface (HMI) port: Interfaces of various hardware and/or software
units allowing the operator to transfer information to a technical system and/or receive
information from the same.
I
Instance ID: The identifying number for objects (for example, points) within a BACnet
device. Instance IDs can be assigned manually or automatically within the range set for
the host device.
Internet Protocol (IP): A connection-less protocol that allows a packet to travel across
multiple networks on its way to its destination. IP is the network layer of TCP/IP suite.
