Beckhoff: New Features TwinCAT 3.1
September 5, 2019
One of the many advantages gained by the integration of TwinCAT 3 into Visual Studio® is the possibility to use source code control procedures which are already familiar from IT for software engineering in automation. Thus, management and revision control of complete configurations and the required program code are much simplified. TwinCAT Automation Interface provides a simple interface for automatic code generation. It enables complete configurations for I/O and Motion along with the corresponding program code to be generated automatically. With version 3.1, TwinCAT Scope is also integrated in Visual Studio®. New channels can be easily created by drag and drop. A link to the source code administration and the automation interface is directly integrated.
The core-isolation mode of TwinCAT 3.1 enables individual cores of multi-core CPUs to be reserved for the exclusive use of TwinCAT. Moreover, 64-bit and CE versions are supported as a platform for the TwinCAT runtime alongside 32-bit operating systems.
