Figure 1.1 – Overview of Device Manager Installation
The diagram above illustrates the three steps necessary to use a Device Manager
to manage a network:
1. The network is designed using the LonMaker for Windows Integration Tool;
2. A Loading Wizard is used to create a “Managed Device List” from the
L ON W ORKS database created by the LonMaker tool. The Managed Device
List is then loaded into the Device Manager;
3. The Device Manager is connected to the control network.
Once attached, the Device Manager will automatically locate and commission all
the devices defined in the LonMaker drawing. No further user intervention is
required to install or replace devices.
After commissioning, the devices on the network will be periodically queried
(pinged) by the Device Manager. If a device fails to respond, an entry will be
made in the Device Manager’s internal event log, and, optionally, a message can
be sent to a monitoring device such as the LNS Alarm Dialer available at
