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 PerfectHOST software Customized Web Pages via Mediator MPX and WebExpress tool
"Thin" Client Browser Mediator hardware allows internet Explorer/Netscape/Mozilla use over the Internet for communication
"Thick" Client Browser PHWIN (perfectHOST) is required to access the system over the Internet (TCP/IP) using a PC or laptop
Product Application(s): N.A.
Handheld Interface Devices (HID)
PDA-Based
Proprietary
Local Display Panel (LDP) RZ integrates with flat-panel LCD touch screens. Modbus RTU, Modbus/Ethernet
Zone Based Interfaces (ZBI)
Thermostat with communication port to access local controller/network Available. All RZ Sensors are available with this option
Other thermostat types available (without communication ports)
Interface to BAS Networks Primary network uses IP protocol and is compatible with IT network / Internet (XML, HTTP, HTTPS, CSV) Also BACnet/IP and Modbus TCP/IP and others
Compatible with the building's IT network? Yes with Mediator MPX
Protocol(s) RZ EIA-485 LAN, LonTAlk over LonWorks FFT-10, BACnet/IP, Modbus/TCP
Cabling and Speeds 9.6 kbps high thru put UTP @ 78.8 kbps (1.25 Mbps transceiver can be used as option)
Expansion Capability RZ Net EIA-485, 1,024 controllers with Multi-net. 4,096 controllers with Mediator. Unlimited quantity of Mediators. Each LON segment or sub-network can have up to 64 nodes without a repeater. Up to 248 routers allow the LON to be expanded to a maximum of 31,744 nodes.
Additional Information The RZ Net can support a wide variety of additional third-party proprietary/legacy protocols, as well as BACnet, LonWorks and Modbus controllers.
Peer-to-Peer or Polling? Peer-to-peer RZ Net Polling - LonWorks
Protocol(s) R/Z Net with numerous Third Party Drivers
Cabling and Speeds UTP @ 9.6 kbps
Expansion Capability Up to 1024 R/Z controllers in 32 sub-networks by 32 nodes per sub-network without a repeater
Additional Information A token-passing, peer-to-peer network management scheme is used to increase network efficiency and information throughput and decrease network 'overhead'.
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.
