TwinCAT Development Environment
The Software for automation TwinCAT (The Windows Control and Automation Technology) will be
distinguished into:
• TwinCAT 2: System Manager (Configuration) & PLC Control (Programming)
• TwinCAT 3: Enhancement of TwinCAT 2 (Programming and Configuration takes place via a common
Development Environment)
Details:
• TwinCAT 2:
◦ Connects I/O devices to tasks in a variable-oriented manner
◦ Connects tasks to tasks in a variable-oriented manner
◦ Supports units at the bit level
◦ Supports synchronous or asynchronous relationships
◦ Exchange of consistent data areas and process images
◦ Datalink on NT - Programs by open Microsoft Standards (OLE, OCX, ActiveX, DCOM+, etc.)
◦ Integration of IEC 61131-3-Software-SPS, Software- NC and Software-CNC within Windows NT/
2000/XP/Vista, Windows 7, NT/XP Embedded, CE
◦ Interconnection to all common fieldbusses
◦ More...
Additional features:
• TwinCAT 3 (eXtended Automation):
◦ Visual Studio® integration
◦ Choice of the programming language
◦ Supports object orientated extension of IEC 61131-3
◦ Usage of C/C++ as programming language for real time applications
◦ Connection to MATLAB®/Simulink®
◦ Open interface for expandability
◦ Flexible run-time environment
◦ Active support of multi-core- and 64 bit operating system
◦ Automatic code generation and project creation with the TwinCAT Automation Interface
◦ More...
Within the following sections commissioning of the TwinCAT Development Environment on a PC System for
the control and also the basically functions of unique control elements will be explained.
Please see further information to TwinCAT 2 and TwinCAT 3 at http://infosys.beckhoff.com.
5.2.1
Installation of the TwinCAT real-time driver
In order to assign real-time capability to a standard Ethernet port of an IPC controller, the Beckhoff real-time
driver has to be installed on this port under Windows.
This can be done in several ways.
A: Via the TwinCAT Adapter dialog
In the System Manager call up the TwinCAT overview of the local network interfaces via Options → Show
Real Time Ethernet Compatible Devices.
