TCP/IP networking in process control plants

This paper refers to the utilization of Transmission Control Protocol/Internet Protocol (TCP/IP) in process control plants. Pertinent characteristics of classical control systems are presented, as a base to comparison with TCP/IP control systems. The advantages and shortcomings of adopting the latter one are pointed out. Integration with Internet-based technologies and systems management is explained next. Some products that provide these features are also presented as well as common components used in corporate networks, which can fully exploit and enhance the versatility of these control networks. Finally, economical aspects of this design are briefly commented.
