A promising direction for the development of industrial enterprises is the Industrial Internet of Things (IIoT) technologies introduction. The paper presents the features of such systems organization and assesses the reliability of the functioning of the wired IIoT system. investigation of an important reliability indicator of a reconstructed wired IIoT system was provided, the availability function (AC), were carried out, which showed that it is necessary to increase the reliability of the server and the system power cables. The paper also assesses the dependability of the IIoT wired system using the mathematical apparatus of Markov models in the event of cyberattacks on the IIoT subsystems. A research of this system’s AC showed, that cyberattacks decreases mostly the AC value of IIoT wired system.
