Application Used in HVAC networks to integrate M-Bus meters and pulse counters into a control system The meter bus plug-in module enables simple connection of heat or energy meters as well as water meters to the meter bus gateway. A maximum of 32 meters conforming to EN 1434-3 may be connected for data transfer. Additionally, the meter bus gateway is equipped with 16 inputs for pulse counting, e.g. from heat or water meters. The meter bus gateway converts the read or recorded data into Modbus data. This allows the meters to be integrated into a control system. Modern control systems, e.g. the TROVIS building control system from SAMSON, visualize and log the meter data, e.g. for billing purposes.
