Yokogawa Electric has released a number of new modules for the Stardom network-based control system, which is ideal for monitoring, operation, control, data collection and data storage applications.

The new modules include control modules with the high speed and reliability required for small to medium-sized turbomachinery, a frequency input module that can accurately measure the speed of even slowly rotating wind-turbine blades and an upgraded central processing unit (CPU) module for oil and gas upstream processes that features improved reliability and greater memory capacity.

For the conventional energy market, Yokogawa also has improved the reliability and functionality of the FCN-RTU low-power autonomous controller that was developed for the control of oil and gas wellheads distributed over a wide area.

The newly developed control modules include a servo module that controls the rotational speed of small to medium-sized turbomachinery and a high-speed protection module that protects machines by detecting anomalies such as excessive rotation speeds.

The frequency input module measures rotational speeds with high accuracy (+/-0.1 per cent of reading).

This is true even at speeds as low as 0.1Hz, ensuring that wind turbines can operate smoothly in all conditions, from strong winds to gentle breezes.

Yokogawa has enhanced the CPU module for the FCN-RTU controller to ensure reliability; specifically, the module now has the same error check and correct (ECC) memory found in high-end PCs and the memory capacity has been doubled to facilitate the long-term storage of gas volume data and other onsite information.

Yokogawa has also enhanced its DNP3 software to comply with the latest DNP specifications and cover a wider range of Scada applications.

The VDS monitoring and controlling software (Scada software) and other software for the Stardom platform now support Windows 7, thus ensuring that engineering, operation and monitoring can all be performed under the latest operating system.

Stardom is an open network control system consisting of components with control, operation and monitoring functionality and is highly acclaimed as it combines the reliability of a DCS and the versatility and economy of a programmable logic controller (PLC).

The autonomous controllers at the core of Stardom have the same control and monitoring functions found in a PLC as well as the information distribution functions of a PC.

They are widely used as intelligent remote terminal units (RTUs) in distributed applications such as natural gas and oil wells.

When used in combination, the FCN/FCJ autonomous controllers and Fast/Tools Scada software give increased flexibility in distributed applications.

Target markets include power generation facilities (steam turbines, wind turbines and hydropower generation facilities), oil, chemical, iron and steel and paper and pulp process plants and oil and gas wells and other widely distributed facilities such as those used in water and wastewater applications.
