How to have both TwinCAT2 and TwinCAT3? Beckhoff TwinCAT (Beckhoff) basic tutorial 1.2 TwinCAT installation configuration
Due to the possible use of both TC2 and TC3, it is recommended to install both, but note that TwinCAT2 must
be installed first, followed by TwinCAT3. If you install them in reverse order, both may not be available (when
opening TcSwitchRuntime, it will prompt that Both TwinCAT are activated, so you cannot disable either). If this
is the case, please uninstall both first. If TwinCAT2 is already installed, when installing TwinCAT3, it will
automatically detect whether TwinCAT2 exists and automatically disable it. You can see that the icon in the
lower right corner of the desktop will turn gray (in addition, it should be noted that TC2 has a 64-bit version,
but it cannot run runtime, only write programs, so try not to install 64-bit software. If the system is also 64-bit,
reinstall it as 32-bit)

There are several options when installing TwinCAT2, and the descriptions of each option are as follows. Generally
, the highest level is installed directly (there may be a 30-day trial or a crack patch available online).
1. TwinCAT CP: For the drive of special keys on beckhoff panel PC or control panel, such as the panel PC in the figure above,
the right 123456, ALT, CTRL, SHIFT, and F1~F12 are standard function keys supported by windows and do not
require installation of drivers. However, we also found that there is a row of white buttons on the left side of
the panel. This is a unique function key on our beckhoff industrial computer. Without installing the driver, these
buttons cannot be recognized and will not be available for programming and debugging in the future. Therefore,
if you install TwinCAT CP, these special function keys can be used normally.
2. TwinCAT IO: Installing this level allows you to read the IO on various buses, which is the driver for various fieldbus IOs.
3. TwinCAT PLC: a PLC programming software that complies with IEC61131-3 specifications, allowing PLC programming
for connected devices. Programming languages include instruction tables, ladder diagrams, function blocks, sequence
diagrams, structured text, and continuous diagrams.
4. TwinCAT NC PTP: Supports point-to-point motion control task programming, and can also install some plugins to
support electronic cam, flying saw and other functions.
5. TwinCAT NCI: Supports complex motion control processing, such as linear interpolation and circular interpolation
Whether it's TC2 or TC3, in addition to installing the main program, there are many additional plug-ins. For more
details, refer to the following PPT (each plug-in may have additional charges. If you can write it yourself, don't use
what it provides, such as interpolation and tracking functions).
Other unused ones can be left out. InfoSys is required for help documentation, and Scope is required for variable
monitoring charts.

You can use this TcSwitchRuntime to switch between 2 and 3 (please ensure that TC2 or TC3 is in the Config
state before switching, and close any open program instances)
