Yokogawa Electric Corporation”s upgraded version of its STARDOM network-based control system is designed to improve the system”s competitiveness in the oil, natural gas, petrochemical, and other energy and raw material markets. Key features of the enhancements are an improved communication function for controlling widely-distributed production facilities and the capability to enhance control system reliability by using STARDOM in combination with other control devices in a large plant. STARDOM is an open network-based control system comprised of function-specific control, operation, and monitoring components that can be interconnected flexibly and on a scaleable basis using networking technology. STARDOM is a good fit for controlling shared-use plant facilities, and can be integrated with Yokogawa’s flagship CENTUM series integrated production control system, which is designed for main process control.
