Glossary
The glossary contains terms and acronyms that are used in this manual.
1
100Base-TX: Fast Ethernet network implementation. 100Base-TX stands for 10Mbps
baseband twisted-pair cable. The “X” stands for 100Base-X, the IEEE identifier for the
media system used by 100Base-TX.
10Base-T: Ethernet network implementation. 10Base-T stands for 10Mbps baseband
twisted-pair cable.
A
Adaptive Control: Closed loop control algorithm that auto-adjusts to compensate for
mechanical system/load/seasonal changes.
AEM/AEM100/AEM200: Devices that allow APOGEE field panel networks to
communicate with the Insight workstation across an Ethernet network. The APOGEE
Ethernet Microserver (AEM) operates on a 10Base-Tconnection, but can also be
routed across low speed networks (for example, across Frame Relay). The AEM100
supports auto-sensing 10Base-T and 100Base-TX Ethernet communication. The
AEM200 adds a second serial port, allowing MMI access without disconnecting from
the Insight network.
alarm priority: Ranking of a point alarm.
Automation Level Network (ALN) Devices: Extends Protocol 2 networks, leased line
Modem, TI-2, Fiber Optic TIs, and TIE.
analog input-electric: Analog input point that receives either a current, voltage, or
resistance input signal.
analog output-pneumatic: Analog output point that outputs a pneumatic signal.
AO-V point: Physical analog output point that generates a voltage signal.
Automation Level Network (ALN): The level in the communication hierarchy that
consists of automation stations, automation devices, Application-Specific Controllers
(ASCs), etc.
B
BACnet: A data communication protocol for Building Automation and Control Networks,
ANSI/ASHRAE Standard 135-2004. BACnet allows devices from multiple
manufacturers to work together on a network.
BACnet Broadcast Message Device (BBMD): BBMDs pass BACnet Broadcast
Messages to other BBMDs on the network, allowing these messages to reach BACnet
devices on the other side of a subnet router.
BACnet Encoded Name: A numeric representation of an object name that exceeds the
APOGEE standard of 30 alphanumeric characters or less per name.
BACnet/IP: BACnet over IP protocol.
BBMD: See BACnet Broadcast Message Device .
broadcast: Destination IP address that represents all interfaces on all hosts. Usually,
this is restricted to all hosts on the local subnet.
C
command priority: Ranking of a point command.
current value: Last commanded or sensed value of a logical point.
