The network-based control system consists of the company’s FCN autonomous controller, VDS web-based human/machine interface (HMI), and the Fast/Tools SCADA package. An E2 bus interface module developed for use in FCN-500 autonomous controller extension units allows construction of systems that have more I/O points and cover a wider area. The open-network control system combines components for control, operation and monitoring functionality in oil-and-gas and small-to-medium plant applications.
