Integration of CAD for Electrical Engineering by Automation of Automation Tools

  • Integration of CAD for Electrical Engineering by Automation of Automation Tools
    Executing fully automated project engineering is extremely difficult for graphics
    oriented computer-aided design (CAD) solutions. When dealing with CAD for electrical
    engineering the situation is different: the right technology and high integration enable a
    company to save a great deal of time, money and manpower through systematic
    information management.
    Information accessibility and exchange are key factors in improving company
    productivity. Despite the excellent information technology now available, putting this
    knowledge into corporate practice is more often the exception than the rule. Information
    still tends to be generated using several methods, in isolated solutions, that are often
    overlooked on incompatible operating platforms, and ultimately, misinterpreted and
    misused.
    The engineering company Has Group (formerly Lafer-Turk), based in Corlu, Turkey,
    exemplifies how productivity can be improved through integrated information
    management. At Has Group, the electrical engineering planning department makes
    systematic use of all available information sources to rationalize its work process. As a
    result, Has Group cut the time it previously spent generating control schematics by 50
    percent.The company attributes its success to the electrical engineering CAD system
    cofaso. Now in place for six years, engineers have used cofaso to automate project
    processing to such an extent that many processes no longer require manual
    intervention. Improved documentation, increased quality and the time and cost savings
    contribute substantially to the company's overall productivity.
    cofaso and Order Processing
    Linking the information level "order processing" with cofaso provides a basis for
    project automation. The focal point for business administration is a server-based MDT
    system at Has Group. The MDT is responsible for the entire article master file and,
    more importantly, for the complete materials management system. Every part and
    manufacturer for the project is specified in the master materials file. This restricts the
    engineer's choices but is essential in the industry.
    In this context, generating a project-related article master file from the related material
    release list directly in cofaso is a logical move. However, the different data formats of

    both systems and the difficulty of interfacing to the MDT prevented the exchange of
    data initially. Instead, the lists were only available in paper form and keying them into
    the cofaso workstation required manual work. Has Group used a creative bridge to
    connect cofaso to databases on the MDT. The company developed its own database
    application to carry out the necessary conversions. An MDT ASCII interface later
    simplified the conversion routine. As a result, assigning the project-related article
    numbers in the circuit diagram and the generating of parts lists was no longer a
    problem. Although far from complete data integration with full data currency and
    consistency, the company has made giant strides toward full engineering database
    integration.

cofaso™ and Mechanical Design

Has Group has made considerable progress toward state-of-the-art solutions in
combining cofaso with the "mechanical design" level. The concept is to standardize
components. At Has Group, key parts in the control system are generated from the
specification of the peripheral electrical components. The specification of the control
system I/O level is followed directly by contents and logic for about 50 percent of the
total required circuit diagrams. Has Group is now making intensive use of these
interrelationships to generate circuit diagrams automatically using cofaso.
For this process to work properly, Has Group equips its materials handling systems
for the textile industry with its own control hardware and standard cable systems. These
control systems are completely decentralized and access the input/output level via a
bus system with plug-in terminals. As a result, the complex transport system has the
flexibility to be divided into largely autonomous, measurable functional units based on
control technology. Simultaneously, a simplified cable display can be selected in the
circuit diagram.
Has Group uses cofaso's open XML program interface to control the planning
processes systematically with the electrical engineering CAD system. The XML
program is based on an I/O-oriented display model which takes account of all wiring
possibilities in a situation at four assignment levels (sensors, terminals, distributors,
control units).
Unlike standard path macros, the program works well with a limited number of
macros, making it a highly workable option.
In practical terms, Has Group now can transfer information effectively among all
planning departments. First, the mechanical design department specifies all electrical
engineering components except the article number level. Then „manual" notes are
generated in an intermediate processing step. Components from throughout the project
are brought together in these notes and linked to the control unit I/O level. The result is
a special I/O file that automatically generates the relevant circuit diagrams, including
cross-references, component identifications, texts, cabling, connector numbers,
identification numbers, etc., via XML in cofaso.

Documentation and cofaso™
 
The information architecture of electrical project engineering is based on a central
database text. The primary task of this database is to organize the language used in
company communication, the only way to ensure consistent vocabulary, grammar and
logic in electrical engineering data processing.
The text database is accessed during I/O list generation. Once the control schematic
has been completed using cofaso, the designations are normalized and given control
characters. These characters enable flexible report and documentation, including
customer documentation, labeling and installation reference printouts. Translation
programs begin here, including conversion to foreign languages and customer-related
modifications. All import/export operations are controlled by the program and run via
the XML interface to ensure the optimal automation.
A fourth information level allows Has Group to process graphics files in cofaso.
Graphics are the various machine layouts provided in the form of DXF files by CAD
systems for mechanical design.
These layouts are analyzed in terms of electrical engineering requirements before
they are copied to cofaso as free graphics pages. There, the component's position and
designation can be inserted directly and the complete graphics can be incorporated into
the project documentation.
 
Output Devices and cofaso™

Has Group continues its integrated data processing in electrical project engineering at
the output device level. In addition to printing documentation reports and schematics,
the company uses cofaso to control labeling systems. In these situations, cofaso
produces output with a known (Phoenix, Klemsan, Weidmüller, ...) plotter which copies
the information required to print signs, terminal strips, cable symbols, etc.,
automatically from corresponding XML files and then processes this information for
printing directly or over own application.
cofaso combines electrical engineering documentation with the Has Group operating
system. This graphics-based control and display system displays cofaso pages
automatically for diagnostic purposes.
