KT-Elektronik ModBus-MBus-Gateway

The ModBus-MBus-Gateway serves to integrate M-Bus meters into a control system in networks of HVAC systems.

With the ModBus-MBus-Gateway convenient connection of heat meters, electric meters and water meters is possible. You
can connect up to 6 meters according to EN 1434-3.

The ModBus-MBus-Gateway converts the scanned or acquired data in Modbus data. Modern control systems such as
"TROVIS LEITTECHNIK" by SAMSON visualize and monitor the meter data for billing, for example.

Operation of the ModBus-MBus-Gateway: data from up to 6 meters configured are read cyclically via MBus from meters and
stored in an internal memory of the ModBus-MBus-Gateway. A control system can read the last temporarily stored meter
data via Modbus from the ModBus-MBus-Gateway.
