Overview

This chapter deals with the implementation of TwinCAT 3 in C/C++. The most important chapters are:

• Basics
  Which platforms are supported? Are additional programs required to implement TwinCAT 3 C++ modules?
  The answers can be found in Requirements and Preparation, the following limitations apply.
• Quick start
  This is a "less than five minute example" to implement a simple, cyclic counter in C++. The counter value is monitored and overwritten, debugging options are described, etc.
• MODULE
  Modularity is the basic philosophy of TwinCAT 3. An understanding of the modular concept of TwinCAT 3 is the basic requirement, especially for C++ modules.
  Basic knowledge of the architecture of TwinCAT modules is required.
• Wizards
  Documentation of the visual components of the TwinCAT C++ environment.
  This includes tools for creating projects and tools for editing modules and configuring module instances.
• Programming reference
  This chapter contains detailed information on programming in TwinCAT C++. Here you will find interfaces and other TwinCAT functions for ADS communication and auxiliary methods.
• The "How to ...?" chapter contains useful tips for working with TwinCAT C++.
• Samples
  Some interfaces and their use are described in detail in the form of an executable program, which is provided as a download with source code and solution.
