Description
The widespread industrial automation has made the work of many companies easier and faster. Automation systems not only control countless processes, but also collect huge amounts of information, which are then used to monitor and control equipment and machines. To control the flow of information, databases and communication standards were created.
During the reading, the reader will get acquainted with the mechanisms of transferring information in the computer system of industrial process control. He will learn how operating systems are built and what computer systems are used in industrial automation. The author also introduces the basics of communication technologies used in the operation of the company's information system infrastructure.
The book includes such issues as:
- General model of company's information systems infrastructure
- Industrial computer networks used in automation systems
- Construction of operating systems constituting the operating environment for computer applications in control and process data acquisition
- Review of information technologies used in the creation of industrial automation computer systems, including OPC communication standards
