IzoT CT is the standard design, commissioning, and network maintenance software for 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, adding support for native IP-70 (LON/IP) devices and interfaces in addition to classic LON devices and interfaces. IzoT CT is compatible with the LonMaker Integration Tool, eliminating the need for per-device fees (credits), and adding an updated user interface, compatibility with a newer version of 32-bit Visio and 64-bit Windows 10 and Windows Server 2019, and support for LON/IP devices on IP-70 channels.
