Universal gateway Modbus - LonWorks 



 Universal gateway Modbus - LonWorks 

LM-GATE is a freely configurable gateway between LonWorks and Modbus RTU networks.  LM-GATE allows the integration of Modbus devices into LonWorks and LonWorks devices into the Modbus network.


In Master mode, LM-GATE allows you to poll multiple Modbus slave devices and associate them with LonWorks devices. In Slave mode, LM-GATE 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. Configuration of LM-GATE is performed via RS-485 port with the help of free LM-GATE Tool.

LM-GATE Features
