Central HVAC systems

Integrated building automation

The control of heating, ventilation and air conditioning systems is very important in building

automation, both concerning the well-being of the user and the reduction of energy consumption.

Alongside the standard hardware portfolio for integration of all data points, Beckhoff provides

a software tool that covers the entire scope of functions of an intelligent HVAC control system.

The TwinCAT PLC HVAC software library offers programmers and users the following beneﬁ ts:

efﬁ cient parameterisation and commissioning, a consistently high level of system functionality,

good readability and expandability of programs, ease of maintenance over many years, ﬂ exible

expandability of systems, improved reusability of templates for systems or system modules, easy

training of service personnel, deﬁ nition of a clear, object-oriented program structure, and good

documentability of programs.

The system is rounded off by manual operating modules for

integration into control cabinet doors; these allow monitoring and

operation of the system without having to open electrical cabinets.

Process data is represented directly using the K-bus in the PLC. The

coloured conﬁ gurable LEDs give a clear view of the system status.

Energy data collection

Running a system efﬁ ciently requires a lot of measurement

technology. Besides its standard portfolio of hardware and software,

Beckhoff offers as part of its TwinCAT Building Automation Library

function blocks that simplify using the KL3403 Power Measurement

Terminal considerably.

These function blocks provide effective and peak values for current,

voltage and power. In addition, the free M-Bus library offers many

options for reading data from M-Bus slaves with the KL6781 and

processing it directly in the PLC. In combination with the multi-meter

terminal, TwinCAT Scope 2 provides an easy-to-use tool for collecting

data and analysing signals graphically.
