Commission the controller for LonWorks communication. See instructions below.
Commissioning the controller for LonWorks communication
Before a device can communicate on a LonWorks network, it must be commissioned. Commissioning allows the
system integrator to associate the device hardware with the LonWorks system’s network layout diagram. This is
done using the device’s unique Neuron ID.
A network management tool such as Echelon’s LonMaker is used to commission each device, as well as, to assign
addressing. Specific instructions regarding the commissioning of LonWorks devices should be obtained from
documentation supplied with the LonWorks Network Management Tool.
