            ClimateTalk 2.1 Generic Application Specification R00

            NEMA BS 31013-2024 | Status: Active | ID: 101054

            ClimateTalk is an open standard that defines a set of messages and commands to enable interoperability, enhanced user interface, and machine to machine control independent of the physical layer connecting the devices. 

            The messages and commands defined by ClimateTalk Information Model (CIM) are the presentation and application layers as defined by the OSI Model .  ClimateTalk Applications are fully defined at Layer 7 of the OSI model by a combination of a Device Specific Application Profile, the Generic Application Specification and the Command Reference. 

            ClimateTalk messages can be carried over any physical medium following the OSI model. The ClimateTalk Presentation Layer defines how messages are executed over the various physical mediums in use.  

            CT-485 and CT-LWP are wired serial physical and network layers designed to support the formation of ClimateTalk networks and transport ClimateTalk messages, but other OSI based protocols – including wireless transports - can be used as well. 

            This document defines the generic application requirements for all devices designed to ClimateTalk Open Standards.  This profile defines how all devices interact with other devices on a ClimateTalk network.  Profiles begin with the requirements in this document and expand on them to satisfy the needs of their application.

            The ClimateTalk Open Standards package shown in Figure 1 - OSI Layers for ClimateTalk Implementation prescribes the mandatory requirements to ensure proper network formation of interoperable devices.  Membership in the ClimateTalk Alliance as well as successful completion of mandatory conformance testing is required for listing a product as a ClimateTalk Certified Device.
