FOXBORO FBM207 P0916PH DCSmodular
Foxboro DCS module 20x-23x provides reliable high-capacity interface between DeviceNet I/O equipment and I/A series DCS
No expensive gateway is required for data exchange. This module saves the engineering workload and time, and reduces the failure points
And provide customers with a unified environment to control and monitor their assets in a collaborative view. In addition,
It enhances the openness of I/A series DCS and provides interoperability with multiple devices and protocol types from multiple vendors.
With Foxboro I/A series systems, customers can maintain their equipment and supplier preferences because the platform can accommodate them. Foxboro I/A Invensys Operation Management Company uses Foxboro ® I/A Series ® Distributed control system (DCS) provides first-class water supply control system. The recent implementation has improved the operation concept, improved the performance of startup and operation time, and greatly reduced unplanned unit tripping and shutdown.
These advanced control technologies can reduce the interaction required by the operator and increase the time for automatic control – including during the startup and shutdown of most unit trips – so that the entire control system is more capable of handling the interference conditions and normal operation during the process. Before I/A Series DCS was installed on the feedwater control of Omaha Public Power District in Fort Calhoun Station, there were many operational challenges. The controls are not well adjusted. During power changes, level disturbances are not uncommon and low level control is poor.
John Steinke, the senior nuclear design engineer of the facility, said: “Three element control of split range is adopted on the bypass feed water valve and main valve, allowing automatic control to handle the switching from bypass to main valve. This reduces the direct manual interaction of operators, thus reducing the challenges of operators. We also rotated our steam generator feed pumps. The split range three element control greatly reduces the disturbance associated with rotating these pumps. The more accurate adjustment and control maximizes the capacity coefficient (power generation capacity) of our unit, and eliminates the unnecessary burden of licensed operators who operate the system. So far, we have not tripped due to DCS, nor have we obtained additional downtime.
