CODESYS Installation
Installation of the CODESYS development environment (CODESYS Development System V3) for use with powerIO products.
The CODESYS version we currently recommend is 3.5.21.2 with our "Setup Configuration File"
Our current templates and libraries have been tested with this version. The current CODESYS version is thoroughly tested and our templates for it are published. Our newsletter keeps you informed about new versions.
Explanation
Specifying the CODESYS version (e.g. 3.5.21.2) alone is not sufficient to ensure an identical and error-free installation on different computers. A CODESYS installation is additionally affected by numerous add-ons, each of which may be available in different versions.
To still ensure a uniform installation with exactly defined add-on versions, CODESYS provides so-called "setup configuration files".
We provide you with such a setup configuration file for download available.
We generally recommend carrying out the CODESYS installation using our latest setup configuration file.
Advantage: All our project templates and macros were created with this setup configuration. As a result, you work in exactly the same environment as our developers.
If you want to use a different CODESYS version or a different configuration, we can only provide limited assistance with support requests. In such cases, we reserve the right to charge support as a paid service.
We continuously monitor the release of new CODESYS versions. When new versions offer useful improvements, we update our templates accordingly and provide a new setup configuration file for download.
Note: We recommend not downloading the full installation file directly from the CODESYS Store. Instead, download only the CODESYS Installer and perform the installation using our setup configuration file.
Installation guide
Follow these instructions for a correct CODESYS installation in order to participate in our training sessions or use our templates for productive projects:
Create a CODESYS Store account Go to the CODESYS Store and create a free user account.
Download the CODESYS Installer Search for "CODESYS Installer" in the CODESYS Store or use the download link.

Install the CODESYS Installer Start the downloaded installation file and install the CODESYS Installer on your computer.
Download the powerIO setup configuration file Go to the powerIO download area to the section "CODESYS HVAC → CODESYS Setup Configuration File" and download the latest setup configuration file.
Start the CODESYS Installer Start the installed CODESYS Installer.
Add a new installation Click "Add installation" in the top right and then select "Express".

Select setup configuration file Select the setup configuration file you downloaded earlier.
Set installation options If needed, assign a name for the installation. If possible, activate the option "Create separate repositories".

Install add-ons dialog The required add-ons have already been selected by the setup configuration file. Therefore, click directly on "Install".

Confirm installation Confirm the final security prompt with "Yes" and allow Windows to perform the installation. The installation process usually takes about 20 minutes.
After installation
You can start CODESYS via the Installer by clicking "Start" for the corresponding installation. The CODESYS Installer can manage several different CODESYS installations in parallel.
Recommendation: Freeze installation
After a successful installation, we recommend setting the installation in the Installer to "frozen". This prevents add-ons from being updated accidentally and your development environment from changing unintentionally.
If you want to test a new CODESYS version, we recommend installing it in parallel as an additional installation. The frozen installation should not be changed in the productive environment. By using the "Create separate repositories" option during installation, the library managers of the different versions do not affect each other. This means that in your productive environment, CODESYS will also not suggest updating to newer libraries that were installed on your computer by the newer CODESYS installation.
