15、rk International, a non-profit standards development association. This work has been modified from its original creation to update it to the latest revision. Similar documents have been used in other international standards bodies. This standard is part of a series of standards for open data transmi
16、ssion in building automation, home automation and control, and in building management systems. The content of this standard covers the data communications used for management, automation/control and field functions. The CEA-709.5 is part of a series of ANSI/CEA-709 Standards under the general title
17、Control Network Protocol (CNP), which comprises the following parts: Part 1: Protocol Stack Specification Part 2: Power Line Channel Specification Part 3: Twisted-Pair Communication Part 4: Fiber-Optic Specification Part 5: Implementation Part 6: Application Elements At present this document exists

19、nagement Overview This standard specifies the Layered Implementation Guidelines (LIG) for the Control Network Protocol (CNP) Specification: ANSI/CEA-709.1-D. The CNP specification model is based on the ISO Open Systems Interconnection Reference Model. There are also important extensions to the 7-lay
20、er OSI Reference Model. Figure 1 shows the scope of this specification in reference to the CNP and companion specifications for handling various data-transport media at the lower ISO protocol layers. A dashed line is used to show that the scope of this standard is not as redundancy to the other spec
21、ifications covering their respective layers but as a complement to those specifications in implementing them in an interoperable fashion. In this standard, the guidelines for implementing a device based on CNP are specified to increase the ability for devices to interoperateregardless of installer o
22、r manufacturer of the devices. Anything outside this boundary is covered in other parts of the standard. Similar specifications exist for CNP data-transport media. Draft CEA-709.5 2 This standard has been prepared to provide mechanisms through which various vendors of building automation, control, a
23、nd of building-management systems, may exchange information in a standardised way. It defines communication and internal-documentation requirements. This standard is contributing to the general US policy for energy savings for building automation, monitoring, and control of energy consuming systems

26、te the exchange of data and control information in an interoperable fashion using ANSI/CEA-709.1-D and its associated data-transport media specifications. This standard establishes a minimal set of rules for compliance. It does not rule-out extended services to be provided, given that the rules are
27、adhered-to within the system. It is the intention of the standard to permit extended services to coexist and defines the bounds in which those services function, including the format for internal device-documentation of those services. Services outside purvey of this specificationso long as they are
28、 adherents of the systemare permitted but will not necessarily be interoperable with any other devices and shall not be essential for the functioning of the device. Certain aspects of this standard are defined in other documents. These documents are referenced where relevant. In the case where a ref
29、erenced document conflicts with this standard, this standard will prevail. 2 References 2.1 Normative References The following referenced standards are indispensable for the application of this standard.

33、s and Definitions For the purpose of this standard, the terms and definitions given in ANSI/CEA-709.1-D and the following apply. 3.1 application set function block or function blocks to which a configuration property applies EXAMPLE A network variable, a series or compilation of network variables, a
34、 functional block, a series or compilation of functional blocks, or the entire device. 3.2 base type fundamental type that can be used as the basis of a network-variable type or configuration-property type. NOTE The available base types are defined in section 5.1.2.2. 3.3 changeable-type network var
35、iable network variable whose type can be changed during installation NOTE See 4.8.3.3. Draft CEA-709.5 4 3.4 configuration property (CP) data value used to configure the application program in a device NOTE Configuration properties are used to set parameters such as maximum, minimum, default, and ov
36、erride values. CPs are implemented using configuration network variables or as data items within configuration files. Configuration-property data are kept in a devices non-volatile memory. 3.5 configuration-property member part of a functional profile NOTE See 3.22. 3.6 configuration-property member
