The integrated control system unifies systems of three types, that is electrical (E), instrumentation (I), and computer (C), which have been planned separately so far, and realizes superior cost performance by eliminating functional redundancy and operational disunity and getting engineering unified and easy. Fuji Electric named it "EIC-integrated control system" and has supplied the systems to customers in various fields for years. This paper describes the target, present status and prospects for system integration.

With the diversification of market needs, production systems has rapidly become flexible and the integrated control of products and production systems is demanded. Taking measures to meet CIM and promoting integration are important subjects for control systems accordingly.
Fuji Electric has made efforts several years to spread its own integrated control systems. This paper outlines the necessity, methods for realization and recent tendency of the integrated control system derived from our experience.

Industrial automation has progressed from large-scale systems to small-scale ones. The distributed control system MICREX-MS (mini-automation system) facilitates EIC-integrated control in small-and medium-scale systems.
This paper introduces the configuration and features of the system from a viewpoint of integrated control system.

In the plants equipped with production lines, capital investment in pursuit of mass production is shifting to flexible systems that can produce various types or quantities to meet rapidly diversifying market needs. The distributed control system MICREX-MS is a mini EIC-unified control system with superior expandability and adaptability intended for small-and medium-scale plants.
This paper introduces the features, functions and specifications of MICREX-MS system components.

The paper introduces Fuji Electric's attitude toward networks for integrated control system, particularly concerning software. The description covers the conditions around network systems for integrated control systems and an outline of Fuji Electric's attitude, newly marketed components supporting FA personal computers and software MMS/M supporting FA personal computers in connection with MAP, and the contents of software linking the systems of super-minicomputer A series and FA personal computers.

The point of control system integration in a true sense is to realize software engineering tools that can support controllers and system components of computers in a unified manner being unconscious of differences in their language descriptions, language structures and language functions. This paper introduces some of supporting tools developed considering the above purpose: CASE system, supporting tools for computers, and a unified supporting tool for controllers ES50. Also, it refers to prospects for unified supporting tools for the whole control systems.

The iron and steel industry is eager for the automation, labor saving, energy saving and advanced functions of its control systems, and many of the facilities have come to adopt a system integrating electrical (E), instrumentation (I) and computer (C) because of economical merits and rationality. This paper describes the process features, system configurations and function sharing of recent EIC-integrated systems citing the abundant examples of installations.
Those are economical systems with a simple configuration, easy to operate, easy to maintain, reliable and expandable.

Fuji Electric supplies industrial plants with EIC, EC, IC or EI integrated control systems according to the ratio of electrical equipment (E), instrumentation (I) and computer (C) which have been standardized taking over techniques and know-how in the field of each control system.
This paper outlines integrated control systems with a high E ratio, such as computer systems composed by fusing information processing and power electronics, EI-integrated controllers, variable-speed driving systems and various maintenance systems, and the functions of self-finalized EI-integrated small- and medium-scale systems.

The integrated control system used in the field of water treatment has not only improved in handling, monitoring, maintainability and expandability that feature the system, but also has come to make the best use network functions. This paper describes points and considerations in each system design classified by treatments (for drinking water or sewage) and plant scales (quantities of water treated) citing examples of actual installations.

Demands for measures to meet frequent changes in types and quantity, quality improvement for products, and labor saving and automation against labor shortage have rapidly increased in the chemical industry.
This paper describes the recent tendency of integrated control systems that include not only process automation but also material handling automation and production control systems, and the basic ideas and examples of those systems focusing on distributed control systems.

Recent waste disposal has not only a single function of incineration but combined functions aiming at reusing and recycling; that it's a waste disposal plant (incineration plant) has come to be regarded as a productive plant its instrumentation control system is improving toward EIC integration and CIM structuring accordingly. This paper gives its grounds and the features of the control, an outline of Fuji Electric's integrated control system for urban waste disposal IICS-1000, and proposals for integrated systems in future.

Control systems for cement plants in these days require structuring CIM systems combined with the upper-level sales/production control systems to meet diversified needs.
Process control being a part of CIM requires improvement in rationality and productivity, and requires integrated control systems for putting into practice.
This paper describes the tendency of integrated control systems for cement plants and an outline of the systems.

There are various configurations of digital control systems for thermal power plants according to plant scales and customer needs. The large-scale systems of the utility class are totally automated and digitized by distributed hierarchical architecture with a computer at the top. Also in small- and medium-scale thermal power plants, various apparatus integrated and digitized have been put to practical use. This paper describes the present status of those systems in thermal power plants and introduces an outline of the digital control device TGR-500 for the exclusive use of private turbine-generator sets.
