  • If you want to fully use a partly limited app, you have to license the app first.
  • It is not possible to execute more than one Solution App on a controller. If there is already a PLCnext Engineer project on your controller, it will be deleted when installing a Solution App.
  • If there is already a Solution App on your controller, it is not possible to additionally start a PLCnext Engineer project on your controller. However, the download of the project is not prevented by PLCnext Engineer.
  • Delete a Solution App directly via the PLCnext Store or use the WBM as described in the following section. 
  • After resetting your controller to factory default, every app will be deleted, the licenses will be retained.

On the PLCnext Apps page, you can install and uninstall apps. After successful installation you can also start and stop the apps.

Installed PLCnext Apps table

The table lists all installed apps with further app-specific information. This information is read out of the app_info.json file that is a part of every app container. The file contains information such as app name, a unique app ID, the app version, the minimum firmware version that is required, the app manufacturer and the license status. The license status indicates if the app is free, partly or fully limited: 

  • Fully limited app
    A fully limited app has to be licensed before usage. It cannot be started without a valid license.
  • Partly limited app
    A partly limited app can be used partly , e.g. time restricted use or limited functionality. It can be started without a valid license but has to be registered for unrestricted usage.
  • Free app
    A free app can be used for free without restrictions.

Offline licenses are managed on the License Management page in the Administration area. 

Starting an app

Free or partly limited apps as well as apps with valid license can be started by clicking on the button Start.
