OpenLNS Commissioning Tool

The OpenLNS Commissioning Tool (CT) is the standard design, commissioning, and network maintenance software tool for LonWorks control networks. It makes the power of the OpenLNS network operating system available to network integrators through an easy-to-use drawing interface based on Microsoft Visio 2010.    

  • Provides an easy-to-use design, commissioning, and maintenance tool for LonWorks networks using a simple diagramming interface provided by Microsoft Visio 2010.
  • Includes a core network management platform that has been used in more than 90,000 systems to commission more than 5 million devices, and is supported by hundreds of third-party applications
  • Compatible with all ISO/IEC 14908-1 Control Network Protocol compliant devices with no commissioning fees, credits, or royalties
  • Includes an integrated OpenLNS Server that handles all network management tasks, both for the OpenLNS Commissioning Tool and for all other OpenLNS applications running locally or remotely on any open network
  • Supports multiple simultaneous users, applications, and plug-ins
  • Provides easy integration with third-party tools and applications with OpenLNS and LNS plug-in support and with XML import and export
  • Provides automatic connection-type selection to improve network reliability and reduce common errors when specifying connections

OpenLNS Server
The OpenLNS Server is a platform for creating open control systems. The platform supports multiple applications and service providers, and supplies the essential network services required for installing, operating, and maintaining LonWorks based control systems.

SmartServer 2.0 Controller
The SmartServer is a versatile Web server and controller that connects to any IP network and provides Web services to monitor and control a wide variety of control devices including energy meters, sub-meters, solar panels, micro-inverters, lighting controllers, and building management devices.  The SmartServer can be used as a network interface for the OpenLNS Commissioning Tool, and automatically synchronizes with the OpenLNS Server that is integrated with OpenLNS CT.

U10 and U20 USB Network Interface

The U10 and U20 USB Network Interfaces are high-performance LonWorks interfaces for USB-enabled PCs.  They provide a low-cost method to attach a computer running the OpenLNS Commissioning Tool to a LonWorks network.

OpenLNS Plug-ins

Device manufacturers can use OpenLNS Server to create custom apps for OpenLNS CT that make their devices easier to install and configure.  These custom apps are called OpenLNS plug-ins and integrate seamlessly with the OpenLNS Commissioning Tool.
