This paper describes general features of mini-automation systems among the medium-and small-scale FA systems having increased recently and Fuji's developments to cope with this tendency. Fuji Electric has offered to this field characteristic equipment such as general-use programmable controllers MICREXF, loop controllers Z-series/CC-S, FA computers FASMIC-G/L25, and also various packages for the above equipment such as FA system UFAS, simplified instrumentation systems, personal supervisory and control system FPEC-10, building management system FECS.

The recent rise of the Yen has decreased export and caused hard competition among companies in the domestic market, which has forced them to hasten more severe management.
To cope with the situation, they are introducing FA computer systems for efficient production. Especially for mini-automation, it is most efficient to apply the FA computer system with package software installed.
This paper describes the application of the FA computer systems "UFAS" to mini-automation with an example of efficient application to management.

Recently, in the field of small-scale-plant process control, CRT-operation-incorporated control systems have been used widely, and it is strongly required that they are easy to be introduced and engineered. To meet these requirements, Fuji Electric has developed a simple, compact user-friendly system, Fuji personal supervisory and control system FPEC-10 to serve many users in realizing mini-automation. This paper describes the specification and feature of the FPEC-10 and an example of its application to mini-automation.

Fuji Electric has completed the Fuji integrated energy control system (FECS) series by systematizing its energy control know-how accumulated for many years.
It is applicable to the facilities of medium-and small-scale factories, buildings, shops, and so on as well as those of large-scale factories. This paper gives an outline of the series, and especially, a full description of FECS 100 series applicable to mini-automation.

The PMS is a compound-function controller having both functions of a programmable controller and a microcomputer. It has a wide range of application to mini-automations, since it processes in parallel control functions such as sequential control, DDC control, etc. and data processing functions such as manmachine interface data loggings, etc.
This paper introduces an industrial date logger "LOGFINE" and an integrated operation control system for cogeneration equipment "TOMFINE" out of the many applications.

The industrial microstation L25 is a high-function microcomputer system having real-time multitask OS (operating system) and a high-speed BASIC language. Most of the control, supervision, and data processing which had been handled by costly minicomputers before has come within the application range of L25, leading to fine cost-performance processing. L25, moreover, can be utilized in OA area with MS-DOS loaded. The paper describes an outline and feature of L25 and some examples of application to mini-automation.

This paper gives an outline of the system configuration and control functions of a control system for mixing process in a mixed-feed plant.
The main components for the control system include a high-speed, high-function programmable controller MICREX-F and a man-machine controller PMS-050 of the same kind. The system has successfully automated the setting of mixing date, monitoring, scale control and others.

Fuji Electric has offered single loop controllers, compact controllers, S, and microcontrollers E and H for general-use controllers Z series as digital loop controllers for miniautomation.
This paper gives an outline of the compact controller S and microcontroller H which are digital loop controllers with transmission function and also introduces the F&Z system and P&Z system as an application example to mini-automation.

The automation of small-scale systems has been introduced as a part of FA application to the whole factory so that they may be integrated in the future. For that purpose, the systems accompany material gransfer and handling systems and also include characteristic sensors and components to be intelligent systems. This paper describes some distinctive systems, followed by the description of the trend of distributed automation as automation islands.

Small-scale automated systems in the fields of inspection and testing have been created overcoming difficulties The three examples introduced here have their merits; especially, importance was attached to interfaces with the manufacturing lines and the following processes after inspection or testing.
The color printing line supervisory system gives an example of the automated support system. It fulfills a backup function for the printing machine with an automated adjusting device by displaying static pictures of prints in the line. There is much prospect of development in applications.

Now the repletion of infrastructures is advocated and the improvement of service water and sewage treatment systems proceeds from urban area to rural area. Mini-automation is looked for by local towns where small-scale plants are operated by a small number of people.
This paper introduces a control system for small scale water-supply systems as examples of automation for small-scale water treatment plants, and a supervisory and control system for small-scale sewage treatment systems.
