Echelon OpenLNS Commissioning Tool - Manual (Page 162)

146 Installing Networks
Network Installation Overview
You can install the devices that you added to your OpenLNS CT network design in Designing
Networks. To install devices, you commission the devices and routers in your OpenLNS CT network
design. Commissioning associates the device SmartShape created in the OpenLNS CT drawing with a
physical device on the network and updates the physical device to match the configuration in your
network design.
You can commission devices after you design the network (engineered system installation) or as you
add them to the network design (ad-hoc installation). You can also partially design a network and
commission devices, and then incrementally add and commission more devices to the network.
You can add and commission a device in one step by selecting the Commission Device check box in
the New Device or New Router Wizard. You can set this check box to be selected by default by
selecting the Commission after Creation check box in the Network Properties: Device options
category (see Appendix A).
To commission a device, you specify its Neuron ID. OpenLNS CT then updates the network address
of the device, loads the device application (if necessary), sets the initial state of the device application
(running or not), and updates the device’s configuration properties. You can specify the Neuron ID by
pressing the service pin on a device, manually entering (typing or scanning) it, or manually discovering
the device (see
4
Commissioning using Device Discovery for more information on using this method). A
device is automatically commissioned when you load a new application into it or install it as a
replacement for another commissioned device on the network.
When you commission a device, the network design is updated to include the Neuron ID of the device
and its network configuration. The physical device may also be updated depending on whether
OpenLNS CT is attached to the network and whether it is OnNet or OffNet.
• If OpenLNS CT is attached to the network and OnNet, commissioning updates the physical
device. Specifically, OpenLNS CT associates the Neuron ID with the device and downloads all
network variable connections and configuration properties.
• If OpenLNS CT is unattached to the network or attached but OffNet, commissioning associates
the Neuron ID with the device, but the physical device is not updated. To update the physical
device, you need to attach OpenLNS CT to the network, set OpenLNS CT OnNet, and then
recommission the device. Recommissioning is the same as commissioning except that you do not
have to specify the Neuron ID because it is already stored in the network database. If OpenLNS
CT is unattached, you can only manually enter the Neuron ID (you cannot press the service pin or
use device discovery to specify the Neuron ID).
Commissioning a Device
To commission a device, you do the following:
1. Select the device SmartShape. You can select multiple device SmartShapes to commission more
than one device at a time.
2. Load the application image, if necessary (application devices only).
3. Set the initial state of the application and select the source of configuration property values
(application devices only).
4. Set the Neuron ID.
Note: You must commission a router before commissioning any devices on its far side (the side
furthest away from the OpenLNS Server). The following figure demonstrates a network in which the
devices on the far side of the router cannot be commissioned because the router has not yet been
commissioned.
