This chapter provides a collection of procedures to use the Lonworks driver in online scenarios. Like other drivers, you use
the special manager views and property sheets to configure the network.
Managed vs. unmanaged networks
Lonworks networks may be previously managed or unmanaged.
- In a previously-managed network, all nodes are already installed and commissioned using a Lonworks network management tool.
Each device has a unique subnet-node address, and usually coherent Lon bindings with other devices.You usually want to learn
all existing network management. The driver’s Quik Learn preserves this configuration.
- In unmanaged networks, nodes are installed using default subnet-node addresses, where there are often duplicate addresses
or other address conflicts. Lon bindings between devices do not exist. There is no existing Lon network management to learn
(only to establish for the first time).
Router wiring and configuration
If your network includes one or more routers, you must wire them according to the following rules, and assign Channel Ids and Subnet Ids that match the wired configuration:
Commissioning
The term commissioning to the process that installs software from a central Supervisor PC and station to a remote host controller
on a
Niagara network.
Lonworks also requires the commissioning of networked devices including routers. The Commission button, which initiates this process can be found on the Lon Device Manager, and Lon Router Manger views.
