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 StarVIEW WebAccess software.'SCADA Nodes' are defined as PCs connected directly to LanSTARs. 'Client Nodes' are PCs connected to SCADA Nodes via the Facility Data LAN or Internet.
"Thin" Client Browser Any web browser running on a Windows CE based PDA or handheld computer can view thin client displays.
"Thick" Client Browser Supported browsers include Internet Explorer v6.0Netscape Navigator V6.1. Thick clients runWeb Access Client software to connect to SCADANode.
Product Application(s): N.A.
Handheld Interface Devices (HID)
PDA-Based Any PDA running Windows CE provides snapshot of data in GIF file format. Values,setpoints and digital points can be changed.
Proprietary Any PDA or handheld computer running Windows CE.
Local Display Panel (LDP) Standard. Located on LanSTAR II panel or on MicroSTAR II board.
Zone Based Interfaces (ZBI)
Thermostat with communication port to access local controller/network No
Other thermostat types available (without communication ports)
Interface to BAS Networks StarVIEW WebAccess supports: DDE, OPC, Modbus, ODBC
Compatible with the building's IT network? Yes
Protocol(s) Proprietary IP Over Internet/Ethernet
Cabling and Speeds Compatible with local LAN
Expansion Capability Number of LanSTAR II's limited only by available IP addresses. Each LanSTAR can support up to 32 MicroSTAR II or LCM I/O SCUs. Each SCU can support up to 16 I/O.
Additional Information
Peer-to-Peer or Polling? Polling
Protocol(s) Proprietary
Cabling and Speeds UTP @ at 4.8 kbps
Expansion Capability Up to 32 SCUs (MicroSTAR IIs or LCMs) per LanSTAR II, configured on two trunks of 16 controllers each.
Additional Information
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.
