Migration of plants with SIMATIC (TIA Portal) - Controllers

  • Entry
A certain amount of know-how is required for migrating to new systems. Siemens supports you with many tools and other aids to get successfully into the TIA Portal and the new SIMATIC components.

In order to optimize the performance of a plant, it is useful to check regularly that it is state of the art. A certain amount of know-how is required for migrating to new systems. Siemens supports you with many tools and other aids to get successfully into the TIA Portal and the new SIMATIC components. Here we provide an overview of the relevant topics with links to the most important entries.

TIA Portal

Here you have direct access to the most important technical information and solutions for controllers.


Migration Tool TIA Portal
In many cases a project that you wish to migrate is not on the same PG/PC as the TIA Portal. The migration tool converts the initial project into a compatible format. You can read this file into the TIA Portal and continue processing it.
TIA Selection Tool
The TIA Selection Tool is for selecting, configuring and ordering devices, software and licenses.
