SYSTEM AND METHOD OF MONITORING OF THE EXECUTION SYSTEM OF A PROGRAMMABLE LOGIC CONTROLLER

摘要

Disclosed systems and methods for monitoring an execution system of a programming logic controller (PLC), the method comprising: accessing, by a security module, the PLC execution system and dividing the code and data of the PLC execution system into a plurality of program modules; modifying, by the security module, data exchange interfaces of the program modules used for the interaction between the program modules and the resources of the operating system such that said interaction occurs through the security module, while a format of the data being exchanged complies with a format specified by the security module; and monitoring, by the security module, the execution of the PLC execution system, including monitoring the interaction of the program modules of the PLC execution system with each other and with the resources of the operating system.
