Echelon OpenLNS Commissioning Tool - Manual (Page 56)

40 Getting Started
The devices on the IP-852 channel will not be fully commissioned until you run OpenLNS
applications such as the OpenLNS Server or OpenLNS CT on each of the OpenLNS Server or
OpenLNS CT computers. For more information, see the IP-852 Channel User’s Guide.
Creating and Opening OpenLNS CT Networks
An OpenLNS CT network consists of an OpenLNS CT drawing and an OpenLNS network database.
OpenLNS CT provides several ways to create an OpenLNS CT network, including the following
methods:
• Create a new OpenLNS CT network design. Use this method if you are engineering a new
network, or if you want to redo the logical design of an existing network.
• Use an existing OpenLNS database to create an OpenLNS CT drawing. Use this method to use
OpenLNS CT with a network that was previously installed with an OpenLNS application other
than OpenLNS CT.
• Create an OpenLNS CT network design from an existing physical network, which creates a new
OpenLNS network database and an OpenLNS CT drawing. This method is called network
recovery. Use this method if the network is operational and was originally installed with an
application not based on OpenLNS or was self-installed. You can also use this method with a
network that was previously installed with an OpenLNS application, but does not have its original
network database. OpenLNS CT can recover a network without changing the device applications
or network configuration. See Recovering an OpenLNS CT Network in Chapter 7, Maintaining
Networks, for more information on how to use network recovery and for a summary of the
limitations of network recovery.
• Copy an existing OpenLNS CT network design. Use this method to create a new network that is
similar to an existing network.
Creating an OpenLNS CT Network Design
You can create a new OpenLNS CT network design to engineer a new network or to redo the logical
design of an existing network. To create a new network design, you must use OpenLNS CT as a local
client (OpenLNS CT is running on the same computer as the OpenLNS server).
