DIASYS

HIACS series is a comprehensive monitoring and control system for thermal power, hydropower, and nuclear power plants that brings together Hitachi's rich experience and control technology. In the history of more than 40 years, we have accumulated a lot of application results. As a result, you can achieve that rationalization of the system according to the scale of equipment, compactification by applying remote I/O (reduction of the amount of cable between the field and the electrical room and reduction of the electrical room area), and realization of the latest state at low cost by a partial update according to the status of the control device. In addition, the latest HIACS series supports HMI using web technology and HMI using mobile terminals, collects and analyzes information from the control device, and improves facility availability through early detection of equipment abnormalities. We provide ICT solutions that aim to improve operational efficiency by optimizing inputs.

PMSX®pro has been designed to fully meet all requirements in terms of availability, efficiency, expandability, and flexibility. It also features a high level of harmonized hardware and software and includes a finely tuned range of standardized automation equipment. The process management concept adapts to the plant‘s process engineering structure. Maximum safety, utmost availability, and flexible expandability are obtained by structuring the plant horizontally into function units with specific control and automation tasks. In this way, we achieve a clearly structured, hierarchical, and therefore transparent plant structure. Process-related redundancies are not canceled by the control system. For efficient plant and maintenance management, PMSX®pro provides consistent, plant-wide configuration and parametrization from a central point.
