App management

In contrast to a classic package manager which installs the files of the application to be installed directly in the Linux file system, PLCnext Technology Apps are hosted in file containers (like a zip file) and the system references the files in the container. This procedure allows easy installation and residue-free uninstallation of apps, and also significantly increases the probability that apps are still executable after a firmware update.

 

On a PLCnext Control device, apps are managed by a component of the PLCnext Technology Runtime System called the AppManager.
