CitectSCADA provides DCS-style multi-level redundancy which can be easily configured and incorporated at all levels, enabling it to tolerate a hardware failure anywhere in a system. At St. Fergus all telemetry links and all of the current 10 clients switch automatically and seamlessly in the event of a failure of the primary server. "The success of this project has tremendous cost-saving implications for the oil and gas sector," said Citect UK's Paul Hurst. "It means that production and receiving facilities, whose futures were questionable due to the looming obsolescence of their current SCADA and DCS systems, can remain productive for many more years to come.
