LAST UPDATE: September 2024
IzoT Commissioning Tool (IzoT CT) is the standard design, commissioning, and network maintenance software for LON/IP and LON networks. Install and commission a community of devices by simply drawing your network with the integrated Microsoft Visio tool. As you draw your network, IzoT CT communicates with your devices and automatically configures them to match your drawing. To make two devices communicate, you draw a line between them. The result is a network drawing that serves as the as-built documentation for your network.
IzoT CT is the newest release of OpenLNS CT and LonMaker. IzoT CT added support for native IP-70 (LON/IP) devices and interfaces in addition to classic LON devices and interfaces. IzoT CT and OpenLNS CT eliminated the need for per-device fees (credits) required by the original LonMaker Integration Tool.
IzoT CT includes IzoT Net Server. IzoT Net Server is a LON network management platform for tools and applications for Windows. IzoT Net Server is the newest release of the OpenLNS Server and the LNS Server. IzoT NetServer added support for native IP-70 (LON/IP) devices and interfaces in addition to classic LON devices and interfaces. IzoT Net Server and OpenLNS Server eliminated the need for per-device fees (credits) required by the original LNS Server.
The product names referred to by the IzoT CT and IzoT Net Server software and documentation are not all updated to the new IzoT names, so you may see references to both sets of names in the software and documentation.
IzoT CT is supported on the following versions of Microsoft Windows: Windows 11, Windows 10, Windows Server 2022, and Windows Server 2019.
