A domain controller provides the Active Directory service to network users and
computers; stores directory data; and manages user and domain interactions
including the logon process, authentication, and directory searches.
Active Directory Service Schema
The formal definition of all object and attribute data that can be stored in the
directory
For example, user is an object type with attribute data of name, first name, last
name, e-mail, and so on. The schema is made up of object classes and attributes.
The base (or default) schema contains a rich set of object classes and attributes to
meet the needs of most organizations, and is modeled after the International
Standards Organization (ISO) X.500 standard for directory services.
Active Directory Service—Service Account

only within Active Directory service
This user account provides access to Active Directory service Network Resources.
The account may also provide access to the Metasys system when added and
privileged using the Metasys Security Administration system.

Preferences
Settings that allow you to configure how the Site Management Portal UI behaves,
including the sounds and colors, the startup views, alarm priorities, and the
presence of links to external applications accessible from within the UI
The Metasys system provides customized preferences for the Site Management
Portal UI. Preferences are divided into two categories: system preferences and user
preferences. System preferences apply to all users who log on to the site or device

User preferences do not affect the operation of the system.
Proxy Server
A server that sits between a client application (for example, a Web browser) and a
real server
A proxy server improves performance by filtering requests. The proxy server
fulfills the requests that it is able to fulfill and other requests are forwarded to the
real server. A proxy server may fulfill a request by serving the page or other
resource from a cache. It may filter or alter content and can act as a firewall. If
users access the Site Management Portal UI through a proxy server, they must
have the proper proxy settings configured for the Java platform.
R
RTU
Rooftop Unit
Repository
A location within a database on nonvolatile media programmed to collect and
coordinate active data from one or multiple devices on the network on a
continuous basis
A repository includes alarm and event messages, operator transactions, and trend
data.
Required Annotation
A note that the user must enter when executing an electronic signature
Required annotations exist on MVE systems only. Examples of required
annotations include Normal Process Adjustment and Scheduled Maintenance.
Required Reason
A meaning associated with the signature that the user must enter when executing
an electronic signature
Metasys® System Extended Architecture Glossary Technical Bulletin

Required reasons exist on MVE systems only. Examples of required reasons
include Review, Approve, Operator Action, and Author.
S
SA Bus
Sensor Actuator Bus
The BACnet MS/TP SA Bus connects point devices (IOMs or Network sensors) to
the field controllers.
SCT
System Configuration Tool
A software tool used for offline configuration of NAEs/NIEs, ADSs/ADXs, and
the Metasys system
The SCT provides an easy way to create and edit archive databases offline. The
SCT also provides a logic simulation feature, which allows you to simulate a
building automation device and test the database control logic prior to
downloading it to a device. Using the SCT, you can view and configure multiple
Sites in one archive.
SECVT
Serial to Ethernet Converter
The SECVT functions with a supported NAE55 model to provide N2 Tunneling
over Ethernet. This solution increases N2 application flexibility and allows you to
integrate remote N2 devices into the Metasys network, reducing the need for
hardwired N2 Buses and direct Ethernet connections.
SMTP
Simple Mail Transfer Protocol
SMTP is a protocol for sending e-mail messages between servers
SNMP
Simple Network Management Protocol
SNMP is the primary protocol governing Internet Protocol (IP) network
management and the monitoring of IP network devices and their functions
SNTP
Simple Network Time Protocol
22
Metasys® System Extended Architecture Glossary Technical Bulletin
SNTP is a simplified version of Network Time Protocol. These protocols allow
one computer to ask another computer what time it is across a TCP/IP network,
then set its own clock accordingly. SNTP may be used to synchronize the Site
Director time with a third-party SNTP time server either publicly (on the Internet)
or privately (customer-owned on the LAN/WAN).
Security ID (SID)
Alphanumeric character string that uniquely identifies Active Directory service
users and groups within Active Directory service
Unlike a user name or group name, which may be renamed, the SID remains
constant throughout the life of the user account or group.
Single Sign-On (SSO)
A user’s ability to log on (sign-on) to a network resource (such as a Microsoft
Windows OS) and then access a privileged network resources and/or application
(including the Site Management Portal UI) without providing user name and
password credentials again
Site
A continuously connected network of devices configured as a system for building
control and user access
Site Object
A type of object in the navigation tree that represents the physical network of
connected devices on the site
The device where the Site object resides is considered the Site Director. One
important function of the Site object is to maintain time-of-day synchronization for
a site.
Site Director
A uniform point of entry to the system, allowing you to view all network
components including the information defined in the Site object
For each site, a single engine or Metasys server is designated as the Site Director.
An NAE/NIE may be designated as the Site Director on small networks consisting
of single or multiple NAEs/NIEs. On larger networks with single or multiple
ADSs/ADXs, an ADS/ADX must be designated as Site Director. The Site Director
supports functions such as user logon, user administration, time synchronization,
and data-traffic management. The Site Director is the device that holds the Site
object.

T
TCP/IP
Transmission Control Protocol/Internet Protocol
A protocol for communication between computers, used as a standard for
transmitting data over networks and as the basis for standard Internet protocols
U
UI
User Interface
The UI is a means through which users interact with the Metasys system. Two UIs
are available with the Metasys system:
•
Site Management Portal UI: Traditional UI with complete administration and
configurations capabilities
•
Ready Access Portal UI: Task-based UI that supports a subset of the Site
Management Portal UI capabilities and requires Ready Access Portal software
Universal Principle Name (UPN)
In the Active Directory service, the name of a system user in an e-mail address
format
The user name is followed by the @ sign, followed by the name of the Internet
domain with which the user is associated. The Internet domain may be at the
Forest level of the Active Directory service tree (for example, [email protected])
or at the domain level (for example, [email protected]), or at another
level defined by Active Directory service configuration. The UPN format is based
on Internet Request For Comments (RFC) 822.
User Graphics Tool (UGT)
Software for viewing, creating, and editing graphics to provide a visual
representation of monitored systems
The UGT allows you to quickly check the status of system symbols and recognize
unusual system conditions. The UGT is available with the NAE/NIE, ADS/ADX
and SCT. Graphics can be configured in the Site Management Portal UI and
viewed in both the Site Management Portal UI and Ready Access Portal UI.

Wireless Commissioning Converter
Converter with Bluetooth® wireless technology
The Wireless Commissioning Converter provides a temporary connection between
a laptop running CCT software and the controller to commission, synchronize, and
balance field controllers.
