The open engineering data structure allows external tools to be used for generating, modifying, and managing engineering data.
Allows vendor standard, low-priced PC hardware to be used as the human interfaces. Allows data to be exchanged with a diverse range of software available on the market, including business applications. Higher CPU performance shortens the time taken by the operation and monitoring functions to retrieve windows in response to user requests.
Field Network Recently, activities to standardize the network of field sensors and actuators have increased. The following new functions have also been developed: Long-term data archive function Enhanced graphics functions - Graphic containers - Assignment of generic names of process data - Gradations Control Functions We have already described the fact that it utilizes the same hardware and control program as earlier CENTUMs.
Virtual Test: Yokogawa's original function to test the functions of field control stations allows the carrying out of engineering ranging from system generation to debugging to be accomplished on a PC. Divided Engineering: Facilitates engineering for expansion and modification of the existing system. Independently generated projects can be integrated into one large-scale system.
Quick Online Maintenance: The realization of speedy online maintenance through the use of a fixed-word-length database. Decreased Setting Items in Builders: Specifications that normally do not need to be set are hidden as advanced settings and set at the default values.
Nevertheless, because the interface for the application layer had not been standardized the specifications of communication between a computer and a DCS varied between vendors.
ActiveX Controls: ActiveX is a technology that enables software components to interact with one another in a networked environment, regardless of the language in which the components were created. ActiveX controls are reusable software components that incorporate ActiveX technology and can be used in different machines, because they are machine-independent objects.
In other words, such a window can be shared between an HIS and other computers. The device management function reduces the man-hours required for maintenance, thus resulting in the reduction of the total cost of ownership TCO. Batch Control Functions Batch control had not until recently been standardized because batch processes are applied to diverse industrial sectors, and the product types handled and processes themselves are complex.
While running the existing control applications, communication with upper-level information systems will be enabled and the user will be able to use the new operation and monitoring functions of the CENTUM CS The OPC technology is used for process data access.

Documents are printed in A4 size, but only about half a page can be read on a CRT without scrolling. Also, since the English version has a little more volume of text that the Japanese version, the English version is likely to have a page break if the corresponding text in the Japanese version runs to the bottom of the page. A page break may result for the same reason if any description is added in a revision.
Taking this factor into account, the page layout was designed so each page has as large a space as possible at the bottom of the page. The main design items are listed below. These items are all specified as a style on the DTP tool and produced on the basis of its template.
This style has achieved the readability of paper documents and has high visibility on a CRT. The user interface has implemented the information retrieval capability that allows a description that is possibly dependent on an operating situation to be referred to or browsed, in addition to the PDF properties that allow an electronic document to be browsed and retrieved using the Acrobat Reader, and the contents as viewed on a CRT to be printed on demand. This interface provides a document in the PDF file format that can not only be read with the Acrobat Reader, but can also be improved for use as an online manual for system software.
Practically, the user interface uses the developing tool in the Acrobat Reader's browsing function, and also allows the document on a CRT to jump to the desired topic by setting links in a PDF file. The interface provides especially easy access to the desired information when referring to detailed information about the engineering item from the window for performing engineering work. Form functions on Acrobat and JavaScript are installed as a part of the interface, and they can also function as manual information displays through a pop-up menu and user selectable list boxes.
The major items of the user interface design are described below. The information retrieval capability has been improved through appropriate links. The items to be discussed concerning the design of PDF files include the directory structure and file names in a CD-ROM, and the display magnification, thumbnails and bookmarks, to be set.
Also, electronic documents require a rule for security and must be designed such that trademark and copyright descriptions, as well as precautions can be easily identified by users. It is regrettable that the functions cannot be actually shown. We have achieved the first installation of the electronic documents on the control system by putting stress on document planning and design.
There are about 6, pages of documentation and 25, PDF link settings in the most recent Japanese version. The numbers are similar for the English version. There are two methods of retrieving the required information, as shown below.
The setting of links in the reference manual enables the user to freely browse between documents. The definition items in the window of the current engineering work are displayed as a list by calling them from the Builder window. By selecting an item the engineer wishes to inquire about from the list, the page where the item is described can be jumped to Figure 8. The definition item list changes the display contents for each Builder window.
In other words, the definition item list is a sort of situation-dependent online manual. There are various methods for retrieving information.
The general retrieval procedure is given below. The objective information can be accessed by approaching each manual from the document map, or by retrieving the information from a main index item and definition item. Since the Acrobat Reader's retrieval function searches all data in the currently open field, the reference manual PDF is designed so that each block of related functions consists of one file.
This has improved the retrieval-hit rate. The Acrobat Reader's print function allows the currently displayed page to be printed on demand or one volume of the document to be printed in its entirety. The PDF property reproduces the printed matter that has to be laid out on the screen and allows it to be printed in high quality.
In future it will be necessary to map out a plan to produce an online manual dependent on the situation of the so-called plant operation. Users require an online manual from which they can quickly access information about various events that occur during plant operation. Also, approaching is a wave technological innovation in DTP and other electronic tools.
A de facto standard may appear in place of the PDF file format. With a close eye on such technological trends, it is necessary to produce more user-friendly electronic documents and electronic documents that have greater reusability.
With respect to the conventional distribution of documents, a great number of man-hours and cost is required to pack and deliver paper documents. Electronic documents, however, can easily be distributed through CD-ROMs or transmitted via an intranet or the Internet. However convenient and advanced the electronic document technology and tools are, primary importance must remain attached to the content rather than the form. With attention to user requirements, we intend to create electronic documents that have a sophisticated user interface and enriched content.

Subjects regarding the quality of manuals, including the solicitation of user requests and improvement measures. Comparing electronic and paper documents, and the proper use of them. Supporting online help situation-dependent help Utilizing intranets and the Internet.
This led to the policy described below. Since the product documents are an important part of the product, the highest priority is given to synchronizing the documentation with the product release schedule. Also, the Japanese and English versions of the documents should be released at the same time.
The documents are laid out so that they can be offered either on electronic media or on paper, with consideration for bookbinding. The total size of the documents should be reduced. The complete documents should be structured such that their readability is the prime purpose.
They should not stick to such a structure as the conventional system block for each function of the development specifications or for each software package. Tools and devices suppress the increase in documentation man-hours required due to the production of electronic documents or the usage of new techniques.
User interface including startup and link.
