Communication line of LonWorks category

Supported types and device versions

A communication with LonWorks networks is implemented via the RNI interface of Echelon devices (SLTA, PCLTA, iLON-10, ...) with the help of the Windows system driver. The driver is installed together with "Echelon OpenLDV Installer" available on http://www.echelon.com. The communication was tested on the following interfaces:


Communication line configuration


Device

Set a device name (e.g. LON1, LON2 up to LONx according to the driver configuration (older devices as SLTA, etc.) or the interface name configured in "Control Panel" -> "LonWorks Interfaces" in case of the new devices as iLON-10 driver, which is installed through the Echelon OpenLDV Installer.

The file ldv32.dll had to be copied into an installation directory of the D2000 System in case of older interfaces. OpenLDV Installer does not require this file.
