Babel Buster® LonWorks® Gateways

Choose the right LonWorks gateway: Managed network or not?

A traditional LonWorks network is a managed network. This means all of the LonWorks devices are bound to each other by a LonWorks network management tool. The original such tool was Echelon's LonMaker, but additional companies later created their own network management tools.

How do you know if your LonWorks network is managed? If the various LonWorks devices are actively functioning as a system, then it is a safe bet that the network was commissioned by a network management tool such as LonMaker.

Control Solutions' original LonWorks gateways were designed to let you interface Modbus or BACnet devices to the managed LonWorks network. The gateway would exchange data with the BACnet or Modbus device, and present that data as if it were a native LonWorks device on the managed LonWorks network. These gateways need to be bound using the same network management tool as what commissioned the rest of the network.

On the other hand, sometimes you simply have a device sitting there all by itself with a LonWorks communication port that isn't connected to anything yet, and what you really want to do is interface that stand-alone LonWorks device to your BACnet or Modbus network. Control Solutions also has gateways to work this way. They have very similar model numbers, but the -NB suffix on the end sets them apart.

For example, if you want to connect a Modbus RTU device to a managed LonWorks network, then you would use model BB2-2010. If you want to connect an unmanaged LonWorks device to a Modbus RTU network, then you would use model BB2-2010-NB. The "NB" stands for "Non-Bound". Everything is bound in a managed network. If interfacing LonWorks devices without network management binding, then we call it Non-Bound.

If you are uncertain about which gateway you need, please open a support ticket and Control Solutions will be happy to help you select the right gateway. Converting one type of gateway to another is not straight forward, so it is best to choose the right gateway in the first place.
