Introduction

When modifying a TwinCAT project, particularly when modifying to change version numbers, etc, the mapping information can be lost. This can be a time consuming and error-prone process to re-do.

However, the mapping information can be exported before any changes are made and then re-imported

...The reason that the mappings disappear when a project is replaced is because the Instance data is not created - the mappings need an instance to get the textual information of the IO links from

Étape 1 - Load the Project
