Yokogawa Electric Corporation has released an enhanced version of the STARDOM™ network-based control system. With this release, the integrity of the data transferred between supervisory control and data acquisition (SCADA) systems and programmable logic controllers (PLCs) is ensured in challenging upstream oil & gas and other applications.

Development background

The FCN autonomous controller and the FCN-RTU low power controller are core components of the STARDOM network-based control system, which is widely used in applications involving the monitoring and control of oil & gas fields, water supply facilities, and other installations that are often hundreds of kilometres apart. In such applications, the controllers installed at each site send data via a narrowband communications link to the SCADA system at a central control facility. To ensure that no data is lost, such systems generally employ DNP3, an open distributed network communications protocol. The STARDOM system has been enhanced to make better use of the functions supported by the DNP3 protocol.

Product features

With this enhancement, the FCN and FCN-RTU controllers now support a dual connection to DNP3 clients, enabling the same data to be sent to master and backup SCADA systems (the DNP3 clients) at the same time. When the same essential data is stored on master and backup SCADA servers in separate locations, the system can switch over to the backup SCADA server in the event of a disaster or some other eventuality that could cause the master SCADA server to go offline. This disaster recovery system ensures the uninterrupted monitoring and control of oil & gas fields, water supply facilities, and other types of infrastructure.

Takashi Nishijima, a Yokogawa Director and Senior Vice President of Yokogawa’s Industrial Automation Platform Business Headquarters, says: “Dating back to the days when the company introduced its flagship CENTUM system, Yokogawa has continually been focused on maximising system reliability, and this is one of the core values of our VigilantPlant initiative. We have adopted the same policy with our SCADA systems and are able to prevent the loss of valuable data and guarantee total consistency - even when data is transmitted between customer facilities that may be hundreds of kilometres apart. Yokogawa will continue to enhance the reliability of the systems that its customers and society depend on.”
