### CODESYS Installer for Updates

Source: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_codesys_modularization

The CODESYS Installer facilitates the download and installation of updates for the CODESYS Development System and its add-ons. It provides a user-friendly interface for managing installations and ensures security through signed software.

```text
The CODESYS Installer shows all updates which are available for an installation. These updates can be downloaded and installed with just a few mouse clicks. Furthermore, the Notification Center, which is integrated in CODESYS as a dockable window, also lists available updates (exactly suitable to the currently executed installation). From here it is possible to jump directly to the CODESYS Installer so that it does not have to be continuously active. All setups and add-ons provided by us are signed. Therefore, downloading them over the Internet is safe. We have extended the Package Manager with corresponding (partly interactive) test methods.
```

--------------------------------

### CODESYS Installer for Project-Specific Installations

Source: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_codesys_modularization

To guarantee binary-equivalent controller code for existing projects, a CODESYS installation matching the project's requirements can be created. This ensures compatibility without manual compiler version management. Installations can be user-defined and separated from the update channel.

```text
If differences between the current CODESYS installation and the created version are detected when loading a project, then you are given the option to download and install an installation which is exactly suitable to the project. The project will then be opened automatically in this new created version. Furthermore, when loading it is of course possible to select suitable installations which already exist on the machine. In CODESYS Installer, installations get a user-defined name. In this way, you will not get confused if you have to manage a large number of installations. In order not to continuously receive update suggestions for such a special compatibility installation, these are separated from the update channel by default.
```

Source: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_codesys_modularization

The CODESYS Installer enables the creation of duplicated CODESYS installations for testing beta versions of add-ons without affecting the productive environment. Users can configure each installation to receive either released updates or experimental beta updates.

```text
The CODESYS Installer allows you to easily create a copy of an existing installation. For each installation, you can choose whether only released updates or also experimental beta updates should be provided and installed. Previously, a particular service pack or patch could only ever be installed one time on each machine. Since the introduction of the installer, this restriction has been lifted.
