Apparatus and method for identifying system state manipulation of control and regulation units in nuclear technology equipment

摘要

The control and regulation unit (8) in the nuclear technology facility (2), in particular the device (70) for identifying the unauthorized operation of the system state of the programmable logic controller (10), must be able to detect the unauthorized operation in a reliable manner. For this purpose, a monitoring module (82) is provided which monitors the operating state and / or hardware expansion state and / or program state of the control and adjustment unit (8) and generates a notification when the state changes.
