How to Cross-Reference an Elecdes Project

Fundamentals

The Ebase cross-reference function creates a cross-reference report for your current project.

The Ebase cross-reference function can also place cross-reference annotation on all of the drawings in your project without using your CAD package. This is called "back-annotating cross-references".

For general information see Coil and Contact Cross Referencing (Elecdes).

The Cross-Reference Report

The report file, <ProjectName>XREF.dbf, is generated by selecting this function. The file can be used to print or view cross-referencing information and check for errors.

Reports from multiple projects can reside in the same directory, as each report is uniquely linked to its project number by the first part of the filename.

The cross-reference report contains:

  • Duplications of a component or conductor marker with the same name.

  • Devices that have multiple subcomponents inserted on drawings in the current project. Unused subcomponents of a device are also listed.

  • Modular subcomponents [e.g. A detachable auxiliary contact block] with the same tagname as a device will be listed - with spares.

Some examples of symbols that will be cross-referenced are:

  • A terminal intentionally duplicated on two sheets (for the purpose of showing different connections).

  • A subcomponent of a device. e.g. a relay contact.

  • A wire or cable core (conductor) EXTENSION marker showing continuation across sheets.

Sorting

The cross-reference report is sorted by:

  • Tagname.

  • Non modular before modular subcomponents.

  • Errors come last.

  • Subcomponents are in alphanumeric order. e.g. *M0 before *M1

  • If none of the above conditions can be used to sort items, then a/ Drawing name and b/ Position on the sheet are used to sort items.

Tagnames

Elecdes assumes that any symbols with the same name and location represent the same physical object.

For the purposes of reporting, the name of a device is TAGNAME and the location is PNLNO.

Similarly .

  • WIRENAME is the name of a wire

  • CABLENAME and CORENAME combined form the name of a cable core (conductor)

  • TBLOCK and T1 combined form the name of a terminal. The location is PNLNO.

MTD terminals

MTD terminals have the block name TERMPxx.DWG (where xx can be any number). These are recognised by EDS as being the terminals of an MTD device. They are not reported in the materials lists as "parts to purchase" but you can cross-reference the MTD terminals.

Blank names

Blank names (or parts of names) are treated as identical, and hence will cross reference as duplicates! - You must NOT leave components [devices, terminals, wires, cables] unnamed if you wish to use the cross-reference facilities.

If you do not wish to view a symbol's tagname, make its attribute invisible.

Cross-referencing with Zones

If a symbol is placed in an Elecdes zone then references to that symbol will contain its zone number. Zone numbers override all other methods of cross-referencing. If a reference list header or table header appears in a zone then symbols referring to that header will use the zone number for their reference.

"Single Line Zone" areas and their effects

Cross-referencing may show warnings where duplication problems occur as a result of components that have been shown on a single line diagram as well as shown on the equivalent schematic in your project. These warnings may be avoided if Ebase can recognise the single line circuit. To avoid these warnings you must place the single line diagram inside a single line zone symbol's designated area.

Single line zones can be inserted and sized with Elecdes.

Procedure

  1. Save the current drawing, if it is currently open in a CAD session. This ensures that the cross-reference function is not working with an old drawing file while the drawing session has new data.

  2. If you will be back annotating cross-references, you must ensure that none of the drawings in your project are open in a CAD session, as this will prevent Ebase from writing information to them.

  3. Run EBASE.

  4. Ensure your current EBASE project contains the drawing files relevant to a cross-reference.

  5. Check the box for "Cross Reference Reports".

  6. Check the box "Back Annotate Cross References" if you want to place the cross-reference annotation and symbols onto the drawings.

  7. Press the "Compile Reports" button.

  8. As each drawing file in the project is processed a message will appear showing the drawing name and the size of the drawing file. Ebase caches unmodified drawings for speed. If drawings do not appear to be scanned, on successive report generations, it is because they are cached.

  9. During cache scans there is a possibility that the database engine will be busy. You will be displayed a message indicating this and given options to wait or cancel.


The database format report, <ProjectName>XREF.dbf will be available in the current directory.

You may use Database Editor to view database reports.
