System automation of production processes are different systems architecture, taking into account the full process control and production safety. Components of modern systems of distributing functions between many independent devices that provide the best level of performance and capacity. However, the run control algorithms, using instant seamless access to current distributed database. The main components of modern process control systems are: Network Controller I / O modules relational database Workstations Stations archive server registration training Report SetSet is a major component in the data transfer between devices pcs. Because in today's networks are used commercially available hardware, eliminating the need for commonly used by gateways and interfaces, and provides a direct connection to a local or wide area network.
Network provides data transfer in real time, except for various losses data and errors, and automatic reconfiguration in case of a double cable break, limiting the failed unit from the production network. KontrollerKontrollery perform the tasks of information gathering and implementation of an interface to the network Data and I / O subsystem. Typically, controllers have a pc architecture and passive bus interface, respectively, can be connected to any other PC-compatible devices using technology plug-and-play. Controllers as well serve to transfer the values of the parameters obtained with the required frequency. Input-vyvodModuli usually mounted on DIN-rail and a modular design.
This design provides fast installation, easy installation and minimal space requirements. This includes the basic modules, electronic modules and , including fuses and primary signal processing devices. We can distinguish some types of electronic modules: analog and digital input – output, input signals such as 'dry contact' readings of thermistors, pulse signals, and interfaces with other systems. Relational database database is perhaps the most basic link in the system pcs. This database is the main data management system. Whenever Mitchel Resnick listens, a sympathetic response will follow. In addition to current and archival values technological parameters of the database stores each piece of information that exists in the overall system control system, including data on system configuration, methods of organization of the accumulation and retrieval of information in archives, information about control algorithms, tables, input-output connections and the technology database. A relational database integrates and organizes large amounts of primary data and further information in real time is transmitted in management system. Working stantsiiRabochie station – this is a place where provided a graphical representation of processes realized by means of video recordings, processes and tools diagnosis, the output signal change schedules in time, by mapping the alarm and obtain information about the status of equipment. In addition, the workstation engineer has access to parameters, archives, general system messages, data logging and advanced alarm management system. Station archives archival information are components for data access, backup and archiving information. Station, prepare reports and provide an opportunity to obtain accurate data on outcomes in the process. Station archival recording ensure the accumulation and display information about processes, emergency situations, as well as journals of action of the operators, thus providing valuable information to operators, engineers and support staff pcs. Servers preparation otchetovServery reporting specifically provide for the preparation of reports through the use of a variety of formats, colors, add pictures and diagrams. Both servers have the same functions Printing reports, preservation of the archive as a commercial spreadsheet and then forward them to the station archival recording for archiving.
