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
Dedicated APOGEE workstations are PCs running Insight Server or Insight Client software (depending on that PCs functionality within the APOGEE system).
"Thin" Client Browser Access to APOGEE systems is available through Netscape Navigator 6.0+ or Internet Explorer 5.0+. Requires Insight 3.3+, and APOGEE GO software running on a Insight WebServer PC equipped with either Windows NT 4.0 Server and Microsoft IIS 4.0, OR Windows 2000 Server and Microsoft IIS 5.0.
"Thick" Client Browser Information not provided.
Product Application(s): N.A.

Local Display Panel (LDP) Local User Interface (LUI): Siemen's LUI is available for the MBC/RBC, MEC, or FLNC and can be controller or zone-mounted. Consists of a backlit LCD 30-character display. The LUI is used to display/command any point in the associated field panel. Differential Pressure Monitor (DPM): The DPM is a local alarm system used primarily in laboratory and healthcare applications that features audible and visible warnings that notify staff personnel of an unsafe condition, such as a drop in room pressure or an open door. This is typically used in conjunction with the Room Pressure Controller. Fume Hood Monitor (FHM): The FHM is an laboratory application-specific monitor that displays fume hood face velocity from sash position. Used in conjunction with the Fume Hood Controller.
Zone Based Interfaces (ZBI)
Thermostat with communication port to access local controller/network Series 1000 room temperature sensors offer options for digital displays, setpoint adjustment slide, and override. Series 2000 room temperature sensors with display provide an interactive link to Terminal Equipment Controllers (TECs) to view and adjust controller points. Special Application room temperature sensors are available with a plug-in communication port for easy access to the applicable TEC. Options include setpoint adjustment dial and override switch.
Other thermostat types available (without communication ports)
Interface to BAS Networks The Management Level Network (MLN) is recommended for building-to-building (enterprise-wide) communications and control. Interface hardware provides the connection to the individual automation level networks ALNs. The MLN can coexist with the facilities' IP-based data LAN. Connections between the MLN and ALN can be through either or both of the following: MBCs can be connected directly to the MLN with a POWER Open Processor with Ethernet port or by addding an Ethernet Microserver to the MBC 232 port on older MBC Open Processors. Certain models of MECs also have direct Ethernet connection capabilities. A PC connected to the primary network (ALN) can port out to the MLN via a DigiBoard PC Card APOGEE information can be served over the web, to/from OPC-based networks, and/or to BACnet or LonWorks-based networks through appropriate controllers and a server running the appropriate software.
Compatible with the building's IT network? Yes. See above for connection options between Automation Level Network (ALN) and the MLN/facility data network.
Protocol(s) Proprietary 'P2' protocol over EIA-485 or Ethernet TCP/IP, depending on controller model.
Cabling and Speeds UTP @ 115.2 kbps max (selectable) to 9.6 kbps (typical speed are 19.2 to 38.4 kbps)
Expansion Capability Each ALN primary network can support up to 100 primary controllers.
Additional Information
Peer-to-Peer or Polling? Proprietary: Polling LonWorks: Peer-to-Peer BACnet MS/TP: Polling
Protocol(s) Proprietary ('P1') protocol over EIA-485, BACnet MS/TP over EIA-485, or LonTalk protocol depending on controller.
Cabling and Speeds Proprietary: UTP @ up to 4.8 kbps, or wireless LonWorks: TP @ up to 78.8 kbps BACnet: UTP @ up to 76.8 kbps
Expansion Capability Each secondary network interface device (Primary control units or Supervisory Interfaces) can support up to 3 trunks of 32 secondary controllers each for a total of 96 controllers.
Additional Information All FLNCs and MBCs can support the proprietary secondary protocol. Most MECs can support the proprietary secondary protocol. Six MECs can support the LonWorks secondary protocol.
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) Apogee Integrator Cards (Third party interface devices.)
Application Gateway to third-party devices and communications via the ALN primary network. The specific gateway is installed on the open processor within a primary control unit (MBC/RBC or MEC) and provides two-way integrated communication and control of third party devices and systems. Current configurations are available for Carrier, Trane (via BACnet), Johnson Controls, Cleaver-Brooks, Fireye, Honeywell, Leibert, Simplex, McQuay, York, and many others. See website or contact vendor for complete and current list of third-party devices supported.
