LNS DDE Server / Release 2.1 Model 37200 / 37200-20 Features Interfaces HMI and visualization applications installed with LNS tools Reads and writes network variables, conguration properties, and application messages Supports LonMark functional blocks Supports LonWorks IP-852 (ISO/IEC 14908-4) channels for high-bandwidth workstation connectivity. Supports over 3000 updates per second with high- performance LNS 3 runtime. Remote access via LNS or NetDDE Supports multiple clients and networks on the same PC or multiple PCs Provides easy client set-up with a point browser and DDE copy/paste link support Use with hundreds of programs that support the Microsoft DDE protocol Supports Wonderware SuiteLink and FastDDE protocol Description The LNS DDE Server is a software package that allows any DDE or SuiteLink-compatible Microsoft Windows application to monitor and control LonWorks networkswithout programming. Typical applications for the LNS DDE Server include interfaces with HMI applications, data logging and trending applications, and graphical process displays. LNS is the open, standard operating system for LonWorks networks. Based on a powerful client/server architecture, LNS permits multiple installers or maintenance personnel to si- multaneously access and modify a common database. By linking LNS and Microsofts DDE protocol, DDE-compatible Windows applications can interact with LonWorks devices using any of the following methods: Read, monitor, and modify the value of any network variable Supervise and change conguration properties Receive and send application messages Test, enable, disable, and override LonMark functional blocks Test, wink, and control devices www.echelon.com are stored in the devices memory and not The LNS DDE Server connects LonWorks that can be processed by the LNS DDE exposed as network variables. networks to operator interfaces for control Server PC. systems in buildings, factories, processing The LNS 3 runtime, included with the LNS plants, semiconductor fabs, and other com- Easy Access to Every Point DDE Server, implements much of the mercial and industrial applications.
