1.2 DEFINITIONS

The following list of definitions may contain terms not found elsewhere in the Section but are included here for completeness.

a. Application Generic Controller (AGC): A device that is furnished with a (limited) pre-established application that also has the capability of being programmed. Further, the ProgramID and XIF file of the device are fixed. The programming capability of an AGC may be less flexible than that of a General Purpose Programmable Controller (GPPC).

b. Application Specific Controller (ASC): A device that is furnished with a pre-established built in application that is configurable but not re-programmable. An ASC has a fixed factory-installed application program (i.e Program ID) with configurable settings.

SECTION 23 09 23.00 28 - Page 8

c. Binary: A two-state system where an "ON" condition is represented by a high signal level and an "OFF" condition is represented by a low signal level. 'Digital' is sometimes used interchangeably with 'binary'.

d. Binding: The act of establishing communications between CEA-709.1-D devices by associating the output of a device to the input of another so that information is automatically (and regularly) sent.

e. Building Control Network (BCN): The CEA-709.1-D control network consisting of one or more TP/FT-10 channels, and possibly a single TP/XF-1250 channel, in doubly terminated bus topology.

f. Building Point of Connection (BPOC): The BPOC is the point of connection between the UMCS network backbone (an IP network) and the building control network backbone. The hardware at this location, that provides the connection is referred to as the BPOC Hardware. In general, the term "BPOC Location" means the place where this connection occurs, and "BPOC Hardware" means the device that provides the connection. Sometimes the term "BPOC" is used to mean either and its actual meaning (i.e. location or hardware) is determined by the context in which it is used.

g. Channel: A portion of the control network consisting of one or more segments connected by repeaters. Channels are separated by routers.

The device quantity limitation is dependent on the topology/media and device type. For example, a TP/FT-10 network with locally powered devices is limited to 128 devices per channel.

h. Commandable: See Overridable.

i. Configuration Property: Controller parameter used by the application which is usually set during installation/testing and seldom changed.

For example, the P and I settings of a P-I control loop. Also see 'Standard Configuration Property Type (SCPT)'

j. Control Logic Diagram: A graphical representation of control logic for multiple processes that make up a system.

k. Domain: A grouping of up to 32,385 nodes that can communicate directly with each other. (Devices in different domains cannot communicate directly with each other.) See also Node Address.

l. Explicit Messaging: A non-standard and often vendor (application) specific method of communication between devices where each message contains a message code that identifies the type of message and the devices use these codes to determine the action to take when the message is received.

m. External Interface File (XIF): A file which documents a device's external interface, specifically the number and types of LonMark objects, the number, types, directions, and connection attributes of network variables, and the number of message tags.

n. Functional Profile: A standard description, defined by LonMark, of one or more LonMark Objects used to classify and certify devices.

o. Gateway: A device that translates from one protocol application data format to another. Devices that change only the transport mechanism of the protocol - "translating" from TP/FT-10 to Ethernet/IP for example -

SECTION 23 09 23.00 28 - Page 9 are not gateways as the underlying data format does not change.

Gateways are also called Communications Bridges or Protocol Translators.

p. General Purpose Programmable Controller (GPPC): Unlike an ASC or AGC, a GPPC is not furnished with a fixed application program and does not have a fixed ProgramID or XIF file. A GPPC can be (re-)programmed, usually using vendor-supplied software. When a change to the program affects the external interface (and the XIF file) the ProgramID will change.

q. LonMark Object: A collection of network variables, configuration properties, and associated behavior defined by LonMark International and described by a Functional Profile. It defines how information is exchanged between devices on a network (inputs from and outputs to the network).

r. LNS Plug-in: Software which runs in an LNS compatible software tool, typically a network configuration tool. Device configuration plug-ins provide a 'user friendly' method to edit a device's configuration properties.

s. LonMark: See LonMark International. Also, a certification issued by LonMark International to CEA-709.1-D devices.

t. LonMark International: Standards committee consisting of numerous independent product developers, system integrators and end users dedicated to determining and maintaining the interoperability guidelines for LonWorks. Maintains guidelines for the interoperability of CEA-709.1-D devices and issues the LonMark Certification for CEA-709.1-D devices.

u. LonMark Interoperability Association: See 'LonMark International'.

v. LonWorks: The term used to refer to the overall technology related to the CEA-709.1-D protocol (sometimes called "LonTalk"), (including the protocol itself, network management, interoperability guidelines and products.

w. LonWorks Network Services (LNS): A network management and database standard for CEA-709.1-D devices.

x. Monitoring and Control (M&C) Software: The UMCS 'front end' software which performs supervisory functions such as alarm handling, scheduling and data logging and provides a user interface for monitoring the system and configuring these functions.

y. Network Variable: See 'Standard Network Variable Type (SNVT)'.

z. Network Configuration Tool: The software used to configure the control network and set device configuration properties. This software creates and modifies the control network database (LNS Database).

aa. Node: A device that communicates using the CEA-709.1-D protocol and is connected to a CEA-709.1-D network.

bb. Node Address: The logical address of a node on the network, consisting of a Domain number, Subnet number and Node number. Note that the "Node number" portion of the address is the number assigned to the device during installation and is unique within a subnet. This is not the

SECTION 23 09 23.00 28 - Page 10 factory-set unique Node ID (see Node ID).

cc. Node ID: A unique 48-bit identifier assigned (at the factory) to each CEA-709.1-D device. Sometimes called the Neuron ID.

dd. Overridable: A point is overridable if its value can be changed using network variables outside of the normal sequence of operations where this change has priority over the sequence. Typically this override is from the Utility Monitoring and Control System (UMCS) Monitoring and Control (M&C) Software. Note that that this definition is not standard throughout industry; some refer to this capability as "commandable" and some use this term to refer to changing a value from a configuration tool.

ee. Polling: A device requesting data from another device.

ff. Program ID: An identifier (number) stored in the device (usually EEPROM) that identifies the node manufacturer, functionality of device (application & sequence), transceiver used, and the intended device usage.

gg. Repeater: A device that connects two control network segments and retransmits all information received on one side onto the other.

hh. Router: A device that connects two channels and controls traffic between the channels by retransmitting signals received from one subnet onto the other based on the signal destination. Routers are used to subdivide a control network and to control bandwidth usage.

ii. Segment: A 'single' section of a control network that contains no repeaters or routers. There is generally a limit on the number of devices on a segment, and this limit is dependent on the topology/media and device type. For example, a TP/FT-10 network with locally powered devices is limited to 64 devices per segment.

jj. Service Pin: A hardware push-button on a device which causes the device to broadcast a message (over the control network) containing its Node ID and Program ID. This broadcast can also be initiated via software.

kk. Standard Configuration Property Type (SCPT): Pronounced 'skip-it'. A standard format type (maintained by LonMark International) for Configuration Properties.

ll. Standard Network Variable Type (SNVT): Pronounced 'snivet'. A standard format type (maintained by LonMark International) used to define data information transmitted and received by the individual nodes. The term SNVT is used in two ways. Technically it is the acronym for Standard Network Variable Type, and is sometimes used in this manner. However, it is often used to indicate the network variable itself (i.e. it can mean "a network variable of a standard network variable type"). In general, the intended meaning should be clear from the context.

mm. Subnet: Consists of a logical grouping of up to 127 nodes, where the logical grouping is defined by node addressing. Each subnet is assigned a number which is unique within the Domain. See also Node Address.

nn. TP/FT-10: A Free Topology Twisted Pair network defined by CEA-709.3.

SECTION 23 09 23.00 28 - Page 11

This is the most common media type for a CEA-709.1-D control network.

oo. TP/XF-1250: A high speed (1.25 Mbps) twisted pair, doubly-terminated bus network defined by the LonMark Interoperability Guidelines. This media is typically used only as a backbone media to connect multiple TP/FT-10 networks.

pp. UMCS Network: An IP network connecting multiple building control networks (BCNs) to the Monitoring and Control Software using the CEA-852-C standard.

qq. User-defined Configuration Property Type (UCPT): Pronounced 'u-keep-it'. A Configuration Property format type that is defined by the device manufacturer.

rr. User-defined Network Variable Type (UNVT): A network variable format defined by the device manufacturer. Note that UNVTs create non-standard communications (other vendor's devices may not correctly interpret it) and may close the system and therefore are not permitted by this specification.
