M-Bus to Modbus.

New gateway from HMS Industrial Networks enables M-Bus data from measuring devices to be monitored from Modbus-TCP networks.

M-Bus (Meter-Bus) is a widely used communication standard for measuring devices. It is predominantly used in buildings, for example in electricity meters, gas meters, water meters or other types of consumption meters.  By getting data from these measuring devices onto a PLC or SCADA system, users can get a total overview of their energy consumption, including building parameters which previously had to be checked separately.

How the gateway works
The Anybus M-Bus to Modbus TCP gateway decodes M-Bus telegrams and maps meter values to Modbus registers. Mapping and configuration is done in a web-based configuration tool allowing the user to set up the gateway without any programming. It is possible to connect up to 20 M-Bus slaves and enable them to communicate on a Modbus-TCP network.

Connectivity to more networks with Anybus X-gateways
The solution can be extended by pairing the M-Bus gateway with an Anybus X-gateway Modbus-TCP, making it is possible to connect M-Bus devices to most industrial networks. Versions are available for CANopen, CC-Link, ControlNet, DeviceNet, EtherCAT, EtherNet/IP, Modbus RTU, PROFIBUS and PROFINET.

Making energy savings possible
"We see a substantial market for this solution," says Niklas Selander, Product Manager at HMS. "Many industrial companies are currently trying to optimize their energy consumption. Their production lines are often connected to some kind of industrial network, but building parameters such as electricity, water, gas etc. are usually monitored on separate M-Bus systems. With our new solution, we enable plant owners to analyse and optimise their energy usage from PLC´s on Modbus-TCP and other networks."
