TwinCAT – software-based control technology

for building automation

When Beckhoff introduced its PC-based control technology in 1986, the company also created a

worldwide standard for automation. On the software side, the TwinCAT automation suite is at

the heart of the controller. (TwinCAT stands for “the Windows control and automation technol-

ogy”.) TwinCAT converts nearly any PC-based system into a real-time controller with multiple

PLC runtime systems. All building automation systems are programmed and parameterised

with TwinCAT. The engineering environment has been designed for all popular programming

standards in the IT and automation ﬁ elds from IEC 61131 to C/C++. Predeﬁ ned software modules

simplify the engineering process, and functional enhancements or modiﬁ cations are possible at

any time.
