Adapter Modbus - LonWorks 

MB-LON (version 2)

  Adapter Modbus – LonWorks

Адаптер MB-LON

The second version of the popular firewall adapter, created based on the experience of the previous model and the wishes of customers.


MB-LON is a configurable adapter between LonWorks and Modbus RTU networks.  MB-LON allows the integration of Modbus devices into LonWorks and LonWorks devices in a Modbus network.


In Master mode MB-LON allows you to poll multiple Modbus slave devices and associate them with LonWorks devices. In Slave mode MB-LON is polled by a Modbus master and provides access to LonWorks devices.  Data from LonWorks network variables are converted into data for Modbus registers and vice versa. The Modbus register query intervals and update intervals of the LonWorks network variables are freely configurable. The Modbus map of registers and the types of LonWorks network variables (SNVT) are also freely configurable. The only program used to configure MB-LON is the standard LonMaker package.
