2.2 OPERATOR INTERFACE VIA WEB BROWSER
2.2.1 DESCRIPTION
A. General: The control system shall be as shown and consist of a high-speed, peer-to-peer
network of DDC controllers and a stand alone Web Server. The stand alone Web server shall
be a compact device capable of routing peer to peer communications of devices on the RS485 network to either an Ethernet LAN or a telephone line. The Web Server shall be capable
of storing all system device definitions within the Web server and shall not require an external
system manager, computer, or controller to define or access system control devices. The
Web Server will allow users to interface with the network via dynamic color graphics served
over the Intranet or Internet via a standard Web Browser. The Web server shall be capable of
tabular and graphic displays of mechanical systems, building floor plans, or control devices
depicted by point-and-click graphics.

OPERATOR INTERFACE
A. Operator Interface. Furnish one compact Web server interface as shown on the system
drawings. Operators shall be able to access all necessary operational information in the
system via personal computer utilizing standard Web browser software. Computer and Web
browsing software shall not be furnished under this section. The Web server shall reside on
the same Peer-to-Peer network as the Building Controllers.
B. Web Server shall connect via Ethernet to a LAN or to a Phone Line and be able to serve up
controller information to up to four simultaneous operators connected via the Ethernet or
telephone with standard Web Browsers.
C. Hardware. Furnish one compact Web server router with internal 56k modem and ethernet
port for operator computer access. The web server shall have an integrated RS-485 port for
connection to the peer to peer controller network. The web server shall not require a
permanent keyboard or monitor, however shall have an integrated terminal port for
connecting a terminal and keyboard during installation and configuration. The Web server
shall allow file transfer of files from another system for use as graphics backgrounds or
custom displays.
D. Web Browser Interaction
1. The Web server shall be capable of providing the operator, at a Web Browser, with both
tabular or graphical pages of controller data. An operator with the proper password level
shall be able to change setpoint and occupancy schedules or override points and remove
overrides. Dynamic objects shall include analog and binary values, dynamic text, static
text, and animation files. Graphics shall have the ability to show animation by shifting
image files based on the status of the object.
2. Custom Graphics. Custom graphic files may be created with the use of a graphics
generation package. These graphics may be downloaded to the Web server to use as
graphical backgrounds for Dynamic data sent to a Web browser. A text editor shall be all
that is required to combine the custom graphic files with dynamic data points and create
custom display pages for an operator accessing the Web server from a standard Web
browser.
3. Graphics Library. Furnish a complete library of standard HVAC equipment graphics such
as chillers, boilers, air handlers, terminals, fan coils, and unit ventilators. The library shall
be furnished in a file format compatible with the graphics generation package program.
Upon connection to the controls system the Web Server shall have the capability to learn
the controls system and automatically present default web pages for each controller
found.
4. Alarms. An operator shall be able to access a tabular listing of the systems most recent
alarm messages from a standard Web browser. This listing shall include up to 50 of the
most recent system alarms from building controllers.
5. Display Information. An operator shall have the capability to perform basic setup of the
Web Server from a standard Web browser. Basic setup shall include learning new
controllers that are added to the controls system, setting the time in controllers and
changing the display units of the data presented between Metric and Imperial units.
