Introduction to OpenLDV Networking
The OpenLDV driver allows a Windows application to communicate with a
L ON W ORKS network through a locally attached network interface or a remote
network interface. Figure 1 shows the basic components for communicating
with a L ON W ORKS network:
• One or more OpenLDV client applications (for example, an LNS Server
with one or more LNS clients, the Echelon LonScanner™ Protocol
Analyzer, or some other client that does not use an LNS Server), which
use the OpenLDV API
• The OpenLDV driver
• One or more local network interfaces, which use a Windows device driver
provided with the network interface
• One or more remote network interfaces (usually Internet enabled), which
use the xDriver component of the OpenLDV driver
