Modules - Handling

TcCOM modules are implemented and loaded after a build.

This section describes the handling of modules when they are exchanged between systems.

A distinction must be made between the two C++ project types:

• C++ drivers, which create a .sys file so that they can be loaded by the operating system.
• Versioned C++ projects that create a tmx file to load them with the TwinCAT Loader (from TwinCAT 3.1 Build 4024).

Beckhoff recommends using versioned C++ projects as standard. The advantages they offer include the following:

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