Fig.  Practical example: ‘logging lots, process values and measured values’
The storage of these data in the event of a power failure avoids having to declare entire lots as scrap, after switching on again
and checking the components.
3. Securing the process image
The entire process image is saved for fault finding and reconstruction of the events leading to errors. As a result, the state of
individual components within the plant in the event of a power failure is comprehensible for the service personnel and can be
referred to for clarification.
