Abstract: Automation station and method for restoring license keys in a modular automation station which includes a main unit having a backplane bus connection and a plurality of modules having another backplane bus connection, wherein the plurality of modules or the main unit having a respective backplane bus connection communicate with one another via a backplane bus, where the plurality of modules are operated via a license key to provide software-based functionality tied to a respective license key after a module is replaced with a replacement module, and the license key is restored via automated reading of three data blocks, even when only two of the three data blocks are readable and the license key for the software-based functionality of the replaced module is assigned to the replacement module and thus the software-based functionality is enabled in the replacement module.
