The invention relates to an automation system which can be scaled with respect to its availability and safety. It comprises at least one central processing unit (CPU1) or a plurality of central processing units (CPU1, CPU2) which are interlinked to communicate with one another. The system further comprises at least one local peripheral component and at least one communications channel between the central processing unit(s) and the peripheral component(s). Availability and safety of the system are scaled by means of the following measures: redundant and non-redundant use of central processing units, peripheral components and communications channels, use of non-error-protected standard components or error-protected special components, integration or reloading of the functionality required for the various availability or safety levels into the corresponding components and activating the functionality required for the desired availability and safety level by design or programming.
