TOSMAP-DSTM overview

Toshiba's TOSMAP-DSTM covers a wide range of systems to meet diverse needs - geothermal power plant control, coal fired power plant control, combined cycle power plant control and so on. The TOSMAP-DSTM serves as a key to provide superlative operation and control, excellent reliability, and ease of maintenance for power-plant control. TOSMAP-DSTM embodies Toshiba's unrivaled expertise in power-plant control systems, accumulated through decades of experience supplying power plants equipped with the latest electronic technologies.

Comprehensive integration of plant controls
TOSMAP-DS^TM is applicable to high-speed control, such as governor control, as well as standard control, such as heater level control. Toshiba is not only a DCS supplier, but also a supplier of plant equipment including turbine, generator, and heat recovery boiler. Toshiba is the power plant supplier that has decades of comprehensive experience. The integration of boiler, turbine, generator and auxiliary control into a DCS is accomplished by Toshiba's engineering ability and the wide applicability of TOSMAP-DS^TM.
An Operator/Engineer can access/maintain all the plant control systems including boiler, turbine and generator control in the simple manner based on Microsoft® Windows® 2000

Open and flexible system
The TOSMAP-DS^TM utilizes the latest standards and de-facto standards as much as possible to make use of advanced technology and enable an open and flexible system:

• Microsoft® Windows® 2000 for HMI and IES
• Ethernet (100M and 10M) for C-NET and I-NET
• Compact PCI bus for ACS CPU backplane
• DeviceNet^TM for local I/O bus

The HMI and IES using Microsoft® Windows® 2000 provide excellent operational capability, and the C-NET and I-NET using Ethernet, provide an open network for the entire plant communication. The expandable, compact PCI backplane of the ACS CPU provides open system connectivity to industrial standards, and DeviceNet^TM I/O bus enables a flexible interface with plant equipment.

Easy and unified engineering environment To achieve easy engineering, Toshiba provides an Integrated Engineering Station (IES) that is used for engineering, system configuration and maintenance of the HMI, ACS and C-NET. All the engineering work, TAG database creation, logic configuration, display design and log design are unified on the IES station. Automatic TAG linkage between the HMI data and the ACS control logic data dramatically reduces engineering work for communication between display information and logic inputs/outputs. The IES uses the Microsoft® Windows® 2000 environment providing a familiar graphical user interface using functions such as "point and click," "drag and drop", "pull down menu" and "copy and paste".

Fully independent Human-Machine Interface stations
Every HMI station provides all the functions that are essential to monitor and control a power station. This provides the maximum level of duplication and therefore a more reliable system.
Each HMI Station in the system simultaneously and independently receives plant data via C-NET, so the failure of any HMI Station never affects the essential data processing of other HMI Stations. Other systems that use a client/server architecture may be less reliable, as the failure of the server may make plant operation impossible.
The supervisory software and GUI developed by Toshiba on the Microsoft® Windows® 2000 platform, provides state-of-the-art process operation and monitoring most suitable for thermal power plants.

Powerful and reliable Controller The ACS of the TOSMAP-DSTM system uses an advanced high-speed 32-bit microprocessor that enables the system to meet the diverse requirements of today's power plant operation. Toshiba's supreme semiconductor and manufacturing technology is used to realize a powerful and reliable controller. Execution time is flexibly selectable from 50 to 500 ms according to the control requirement. An extra-high-speed controller with 1 ms control cycle is also available for special purposes such as governor control and generator control.
