Application of programmable logic controller in the sphere of industrial automation substantially simplified technological processes control. New data exchange systems and new algorithms are being developed. It leads to enormous variety of comptrollers. Each of them differs by specific set of functions, unique construction and certain control language. In this article we describe structure of PLC, that can help to choose one, and also present the structural analysis of PLC programming languages. IEC 61131-3 standard considered is to provide software developers PLC powerful tools to improve the quality of applications that includes the safety and security applications. However, this lack of standard practices check whether the designed application correspond to the requirements regarding protection.

One of the main obstacles to widespread adoption of neural network methods and models in cyber attacks and detection systems to detect vulnerabilities in the systems resources information systems is the lack of options on which to evaluatetheir effectiveness. Also, there are no methods forassessing the effectiveness and implementation of such. Tosolve this problem has been analyzed a wide range of modern neural network methods and models used in the detection systems. The list of parameters and a method of theiruse for assessing the effectiveness of the design and selectionof these methods and models in the construction of these detection systems. The obtained results allow us to determinethe shortcomings of modern neural network detectiontools and means of cyber vulnerability detection and outlinepromising ways to improve them.
