New TOSMAP-DS distributed control system using de facto standard technologies

摘要

This paper provides an overview of the cost-effective and state-of-the-art TOSMAP-DS distributed control system, which Toshiba is supplying in competitive overseas markets for thermal power plants. De facto standard technologies such as WindowsNT, Ethernet, and DeviceNet were employed in developing the hardware and software of TOSMAP-DS. This feature makes the system cost-competitive, flexible, and user-friendly. In particular, the "tag"-linked concept is introduced in TOSMAP-DS to reduce the engineering effort. TOSMAP-DS can be used for a wide range of applications in thermal power plants, from large-scale coal-fired plants to small-scale turbine control systems (digital-electrohydraulic control systems).
