VLD - VirtualLonDevice framework is our own fully developed EIA-852/EIA-709 node framework which opens possibility to connect regular PC as peer in control network and the control network will see that PC with this software lonworks node as any other controller commissioned in Lonworks network. Furthermore, particular PC with software lonworks node will show up in LonmakerTM as one of control nodes!

VLD framework follows EN 14908 standard as well as ANSI/EIA/CEA-709 and EIA 852 tunneling mechanism over IP standards. Framework currently runs on Windows XPTM, in the future it will be ported to XPe, CE, as well to Linux OS. This unique approach open Lonworks® infrastructure to live entirely in IP world, and still keep compatibility with regular Lonworks® infrastructure. VLD framework allows development of high performance controller applications for EIA- 852/EIA-709 networks.
