Recently, programmable controllers have been utilized for new equipment on production lines in the automobile industry.
However, operators who must use these devices to carry out various operations face difficulties understanding the different methods for programming, ets. of these devices, and for handling the various types of peripheral equipment.
In accordance with the increase in the number of PCs, CAD/CAM systems have become requisite for achieving high efficiency in sequence control design. However, poor PC standards prevent their development.
In this paper, the development of PC systems, as well as methods for the elimination of problems with standardization, are described.
The methods of standardization concern the methods of transmission between the PC and the peripheral equipment, the construction of peripheral equipment and the structure of data in the ladder diagram.
We have developed a PC, a peripheral equipment with a ROM cassette, a handy programming tool with a graphic display (LCD) panel and a cassette loader connected to a CAD/CAM system.
