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
LONDISPLAY - facility management HMI software for systems using open, interoperable LonWorks networks and Echelon Corporation’s LNS (LonWorks Network Services). - enhanced graphical user interface provides intuitive navigation - extensive alarm, event and trend logging enables accurate and reliable analysis - multi-level password protection prevents unauthorized system access - Able to open LNS plug-ins and support lonmark device ressource files LONWATCHER - LonWorks network management tool - fully integrated with Echelon's LNS - create, commission, and maintain open, interoperable, multi-vendor LonWorks® networks - comprehensive support for LonMark® interoperability standards - economical leave behind tool for network maintenance and operations - multi-level password protection prevents unauthorized system access

Local Display Panel (LDP) The Easycontrols EC-Display is a multi-function LCD display equipped with a 3150 Neuron processor. The EC-Display is based on the LonWorks system and can interface with up to 250 variables.
Zone Based Interfaces (ZBI)
Thermostat with communication port to access local controller/network The EC-STAT is specifically designed for single stage and multistage control of heating/cooling equipment such as rooftop and heat pump units. It is based on the LonWorks protocol.
Other thermostat types available (without communication ports)
Zone sensor
Zone sensor w/ occupant override
Zone sensor w/ setpoint adjustment
Zone sensor w/ occupancy sensor
Interface to BAS Networks

Protocol(s) ANSI/EIA/CEA 709.1 (LonTalk)
Cabling and Speeds 78 kpbs
Expansion Capability Up to 30,000 controllers per network
Additional Information Flat, open, interoperable, peer-to-peer
Peer-to-Peer or Polling? N.A.
Protocol(s) N.A.

Additional Information N.A.
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) ilon 100 Web Server
Application The ilon-100 is a Web-based presentation system for LonWorks Networks. Using a standard web-browser with a standard web browser, the operator can view and control devices in any LonWorks network via the Internet or local intranet. It also have a optional modem connection.
Classification Web Server, Remote Network Interface
