Beckhoff: New M-Bus Master Terminals for Building Automation
Bus master system for building automation.
Burnsville, MN — Beckhoff Automation has introduced the new KL6781 M-Bus master terminal which extends the range of the company's energy measurement terminals to include electricity, water, gas or energy meters with M-Bus interfaces. The terminals can be easily integrated into the company's "fieldbus-independent" Bus Terminal system, rendering external M-Bus gateways unnecessary. The KL6781 M-Bus master terminal, in its compact 12mm housing, enables direct connection of up to 40 M-Bus devices, each with 1.5mA current consumption. To connect additional devices beyond that limit, users simply install another KL6781 in the Bus Terminal node. The M-Bus master terminal converts the data from the Beckhoff I/O system into M-Bus-compliant values. A total of 24 bytes of data per terminal are available for this purpose.
The TwinCAT PLC M-Bus software library, which is available free of charge from the company, simplifies the integration of M-Bus devices from numerous manufacturers through predefined profiles.
In addition to building automation, the M-Bus solution can also be used in machine design and plant engineering applications, where consumption meters with the M-Bus interface can be used for logging load peaks.
The M-Bus terminal extends the company's comprehensive I/O portfolio with yet another useful component. With more than 400 different signal types, the Beckhoff Bus Terminal system covers virtually all signal types encountered in building services engineering. It not only supports all common sensors and actuators, but can also integrate all bus systems that are relevant for building services using suitable Bus Coupler types. Subordinate subsystems such as KNX/EIB, LON, DALI, MP-Bus, EnOcean or serial RS232/RS485 connections such as Modbus can be integrated easily via communication Bus Terminals.
