In this paper the results concerning changes introduced into the architecture of connections of an industrial computer network built on the basis of solutions characteristic of the Industrial Internet of Things were described.We introduce the new solutions improving such properties of industrial networks as: reliability, information security and usage of computational resources available in edge elements.The basic goal of the research was ensuring continuous functioning of the industrial computer network.Isolation of critical elements of the technological process can have far-reaching consequences, including local threats to workers' health and life, and even global technological disasters.Continuity of operation as a consequence of the reliability of the components of an information system is one of its most desirable properties.The offered solution is based on the use of multi-channel reconfigured optical bus that is activated when the basic communication channels fail.In addition, the use of the described solutions for the build of a parallel, heterogeneous computing system based on elements of the Arduino and Raspberry Pi and system servers has been described and evaluated.
