                                                  The  technological process  is controlled by industrial logic
                                              controllers  (ILC). The  control  is carried  out  using sensors
                                                of  various  types.  Control  actions  occur  through  executive
                                                 mechanisms.  The  production  level  is operational-tactical

                                                     systems  (SCADA).  The  upper  level  is responsible  for
                                                       Enterprise  Resource  Planning (ERP)  and  Optimized
                                                         Production Planning (APS). All levels are united by a

                                                                  program. Conduct long-term planning for up to

        cycle. The PLM environment is an evolution of PDM technology for CAD / CAM / CAE database
        management.  Electronic document  management  allows you  to  increase  the  productivity  of
        engineering and technical personnel. Reduced logistics and planning errors. At the same time,
        there  is no  rigid connection  between  all parts  of  the  production  process.  Each  level of  the
        management pyramid is automated locally. There is no general production model in this system.
        Data exchange is initiated by the operator. Global automation of the facility according to the
        scheme (Fig. 1) is difficult due to the low speed of computer networks and low productivity of
        industrial computers. System components exchange data, and do not solve a general problem.
               The  advent  of  powerful  servers  and  high-speed  Internet  is fundamentally  changing
        industrial automation concept. Cloud computing and the Internet of Things are becoming key
        tools. The concept of cloud computing (Clouding computing) is interpreted as a technology of
        distributed data processing, in which computer resources and power are provided to the user
        in the form of an Internet service. In fact, this is the development of database management
        systems (DBMS). As a result, a new class of equipment appears which is integrated into the
        Internet environment. The concept of the Internet of Things appears. The source [1] provides
        the  concept  of  the  Internet  of  Things  as  a  network  of  physical  objects  containing  built-in
        technology that allows these objects to measure the parameters of their own state or the state
        of the environment, use and transmit this information. The Internet of Things can exchange
