Modules - Handling

TcCOM modules are implemented and loaded after a build.

This section describes the handling of modules when they are exchanged between systems. These modules are programmed in Versioned C++ projects that generate a tmx file in order to load them with the TwinCAT Loader (since TwinCAT 3.1 Build 4024).

Driver projects

For older projects, Beckhoff recommends switching to the versioned C++ projects, as these offer the following advantages, for example:

• Driver signature via OEM certificates that can be obtained from Beckhoff.
• Versioned storage of the binaries.
• Online Change capability, if required.

After installation under TwinCAT 3.1 Build 4026, a conversion is available on the C++ node for migration from the older projects ("driver projects"). This can be accessed via the context menu:

The migration generates a report as an HTML file that should be taken into account.
