This section distinguishes between Operator Interfaces and Field Interfaces to the BAS. The Operator Interface refers to the main 'front-end' method for accessing and operating the BAS. The Field Interfaces typically access the BAS from the controller-level and have limited functionality, and may include HID, LDP, and ZBI as described below. This section describes the devices only; OI functionality is generally covered in the Software, while Field Interface functionality is detailed further in the individual Controllers
Operator Interfaces (OI)
Dedicated Operator Workstation (OWS)
Dedicated PC(s) with proprietary workstation software
PC with RC-Studio Software (Windows 2000 recommended)
"Thin" Client Browser Browsers supported are Internet Explorer 5.0+ or Netscape 6.0+. Requires RC-WebView software running on a Server (Windows 2000 Server recommended) connected to the Internet
"Thick" Client Browser
Product Application(s): N.A.
Handheld Interface Devices (HID)
Proprietary SETUP-Tool
Local Display Panel (LDP)
Zone Based Interfaces (ZBI)
Thermostat with communication port to access local controller/network SMART-Sensor: this allows operators to adjust points mapped to the SMART-Sensor; examples are occupant override, setpoint adjustment, occupancy sensor, etc.
Other thermostat types available (without communication ports)
Interface to BAS Networks BACnet (B/IP) Ethernet (TCP/IP)
Compatible with the building's IT network? Yes
Protocol(s) BACnet over IP BACnet over Ethernet (10baseT) BACnet PTP (EIA-232) BACnet MS/TP (EIA-485) Reliable over Ethernet Reliable (EIA-485 & EIA-232) SNMP - Simple Network Management Protocol
Cabling and Speeds Cabling is CAT5 for IP, Ethernet and 18-2 shielded for EIA-485. IP, Ethernet @ 10 Mbps, BACnet MS/TP @ 76.8 kbps (9600, 19200, 38400)
Expansion Capability
Additional Information
Peer-to-Peer or Polling? Peer-to-Peer
Protocol(s) BACnet, Reliable, and SNMP
Cabling and Speeds 18-2 shielded cabling for EIA-485 @ 76.8 kbps (optional 9600, 19200, 38400)
Expansion Capability 124 controllers
Additional Information Peer-to-Peer BACnet via EIA-232
Includes a listing of available Gateways, Routers and other devices that provide additional communications flexibility into and out of the BAS. Repeaters, bridges, standard modems and the like are typically not included here. Note: If in use by the BAS, the Internet/building IT Network is extremely open and non-proprietary. If a vendor uses the IT Network, CI devices such as IP routers and hubs can be purchased from third parties.
Model (Device) Application
Model (Device) RC-WebView
Application RC-WebView enhances the Reliable Controls suite of building automation software by providing a Web based access solution that uses Microsoft Internet Explorer 5.0+ in place of client side software. RC-WebView resides on a dedicated server connected anywhere in the World Wide Web. The software configuration is easy and the number of users connected to RC-WebView is only limited by the capability of the server hosting the application. RC-WebView is designed to use the same file structure as RC-Studio, enabling the two applications to present system group data in the same manner. A common file structure allows the two applications to dynamically synchronize data so that the display is the same in either application. RC-WebView allows the operator to use a browser to view and manually override points, adjust weekly schedules and annual schedules, view, graph and print trend and runtime logs, and view and print current alarms.
