The LNS computer runs a LonWorks network management tool such as LN-Builder or LonMaker. LonWorks Network Services (LNS) is the underlying software that performs the actual LonWorks network management tasks, such as assigning LonWorks addresses, binding, running data queries, and so on. These tools provide a user-friendly interface that directs commands down to the LNS computer to perform actual network operations. The LNS computer can either be a laptop, which is only connected to the network temporarily (when changes to the system are made), or it can be a dedicated computer always attached to the network.
