Abstract

A system for threat detection in an industrial production environment comprises a programmable logic controller. This programmable logic controller includes a process image updated according to a scan cycle with process data associated with one or more field devices, a program configured to operate the one or more field devices using the process data, and one or more function blocks. These function blocks are configured to monitor the process data in the process image during each scan cycle, and identify a possible cyberattack based on the process data.
