Overview of connection sequencing

    The Multi-Connection Sequence Terminal symbol allows a single in-line schematic symbol to represent a sequence of wire connections passing through two or more (up to six) terminal strips. For example, a wire connection that must pass through a series of shipping split terminal strips can be represented by a single in-line wire schematic symbol (instead of having to show each individual terminal in the sequence).

    Two sample symbols are provided. Their appearance may be edited or new ones created as required. They are inserted using the AutoCAD Electrical Insert Component tool. Browse to insert. The symbol names are

    H - - 1_MULTI_CONN.dwgwire number changes through the symbol

    H - - 1_MULTI_CONN_NOCHG.dwg wire number does not change through it

    A dialog box interface lets you encode multiple connection sequence information on to six sets of attribute groups carried on the symbol:

    WD_1_TAGSTRIP Attribute to carry first terminal strip number (16 character maximum)

    WD_1_TERMNO Attribute to carry optional terminal number

    WD_1_INFO Attribute to carry additional information such as installation, location, catalog and item number assignments, and any connected cable information

    WD_2_TAGSTRIP Same as previous but for second terminal in the sequence

    WD_2_TERMNO Same as previous but for second terminal in the sequence

    WD_2_INFO Same as previous but for second terminal in the sequence

    through maximum of

    WD_6_TAGSTRIPSame as previous but for sixth terminal in the sequence

    WD_6_TERMNO Same as previous but for sixth terminal in the sequence

    WD_6_INFO Same as previous but for sixth terminal in the sequence

    Click the entry to edit and select the Edit button.

    Note

    For AutoCAD Electrical to recognize this symbol as a multi-connection sequence terminal symbol, at a minimum it must carry attribute named WD_1_TAGSTRIP. Multi-connection sequence terminal symbols do not support some AutoCAD Electrical auto-update and surfing features.

    Edit multi-connection sequence terminal symbol

     Ribbon: Schematic tabInsert Components panelInsert Components drop-downIcon Menu.
     Toolbar: Main Electrical
     Menu: ComponentsInsert Component
     Command entry: AECOMPONENT

    Enter "H--1_MULTI_CONN_NOCHG" in the Type It box and click OK. Specify the insertion point on the drawing.

    Select any entry within a group to view/edit that group.

    Edit

    Opens the Edit entry dialog box so you can change values such as the tag-ID, terminal number, or Installation code.

    Save Changes

    Saves your changes by writing the data to attributes on the symbol (most of these attributes are set as invisible).

    Edit entry

     Ribbon: Schematic tabInsert Components panelInsert Components drop-downIcon Menu.
     Toolbar: Main Electrical
     Menu: ComponentsInsert Component
     Command entry: AECOMPONENT

    Enter "H--1_MULTI_CONN_NOCHG" in the Type It box and click OK. Specify the insertion point on the drawing. In the Edit Multi-Connection Sequence Terminal Symbol dialog box, select one of the six series-connected entries and click Edit.

    This in-line component lets you manually define a connection sequence of up to six series-connected terminal strip points. All are embedded in this single graphical component but are fully reported in the various wire connection reports.

    For example, you might have a wire that connects from a push button and goes out to a field device. But to get to the field device, the wire connection must pass through a local terminal strip, then a shipping split terminal strip, on to a field connection terminal strip, and finally a terminal strip near the field device. Instead of showing all four series-connected terminals in the wire, you can substitute this single "multi-connection sequence" terminal representation and manually define the connection sequence.

    Tag - ID

    Terminal strip tag-ID

    Terminal Number

    Terminal strip terminal number

    Miscellaneous

    Edit box shows saved data values defined by the following selections.

    Installation Code

    Changes the installation code assignment. You can search the current drawing or entire project for installation codes. A quick read of all the current or selected drawing file is done and a list of installation codes used so far is returned. Select from the list to update the component automatically with the installation code.

    Assign short installation codes to components like "PNL" and "FIELD" so you can create location-specific BOM and component lists later.

    Location Code

    Changes the location codes. You can search the current drawing or entire project for location codes. A quick read of all the current or selected drawing file is done and a list of location codes used so far is returned. Select from the list to update the component automatically with the location code.

    Assign short location codes to components like "PNL" and "FIELD" so you can extract cable from/to reports and location-specific BOM reports later. (For example, BOM for all field cables, BOM for all PNL cables.)

    Catalog Data

    You can do a drawing-wide or project-wide listing of similar components with their catalog assignments. During your editing session, the last MFG / CAT / ASSYCODE assignment for each component type you insert into your wiring diagram is remembered. When you insert another component of that type, the previous catalog assignment of the component is set as the default (assuming a previous one was made during the current editing session).

    Find

    Scans each drawing for the target component type and returns a list of what was found. You can make your catalog assignment by selecting from the list.

    Catalog Lookup

    Opens the catalog database of the catalog from which you can manually enter or select the Manufacturer or Catalog values. Search the database for a specific catalog item to assign to the selected component.

    Drawing

    Lists the part numbers used for similar components in the current drawing.

    Project

    Lists the part numbers used for similar components in the project. You can search in the active project, another project, or in an external file.

    • Active project: All the drawings in the current project are scanned and the results are listed in a dialog box. Select from the list to assign your new component with a catalog number that is consistent with other similar components in the project.
    • Other project: Scans each listed drawing in a previous project for the target component type and returns the catalog information in a sub-dialog box. Make your catalog assignment by picking from the list.
    • External file: You can pull catalog assignments from a generic ASCII file created by a word processor or output from a spreadsheet or database program. A dialog box displays the contents of the selected text file. Find and highlight the desired entry. AutoCAD Electrical reads the line of text from the file and breaks it into its component parts. These are displayed in the left-hand list. For each relevant item, highlight it and then pick the appropriate category button in the center column. The highlighted item is transferred to the corresponding category (and then to the Insert/Edit dialog box once OK is clicked).

    Catalog Check

    Displays what the selected item looks like in a Bill of Material template.

    Wire entering this connection

    Click Internal, External, or Both to change the Connection Code (I=Internal, E=External). The code changes the Miscellaneous value as follows: LEFT_TERMDESC=I (for Internal), LEFT_TERMDESC=E (for External).

    Wire leaving this connection

    Click Internal, External, or Both to change the Connection Code (I=Internal, E=External). The code changes the Miscellaneous value as follows: RIGHT_TERMDESC=I (for Internal), RIGHT_TERMDESC=E (for External).

    Wire number

    Manually define the wire number that leaves this terminal connection and goes to the next. If it is the last terminal in the sequence, this wire number assignment is ignored and the actual wire number connecting the right-hand side of the symbol is used.

    Wire layer

    Manually define the wire layer assignment. If it is the last terminal in the sequence, this value is ignored.

    Cable

    Manually define the cable marker tag-ID. If it is the last terminal in the sequence, this value is ignored.

    Conductor

    Manually define a cable marker conductor color value. If it is the last terminal in the sequence, this value is ignored.

    Delete this entry

    Removes the displayed terminal sequence from the overall list and moves any following entry positions up to fill in the gap.

    Insert new before this one

    Moves the current display terminal sequence down one position and creates a new, empty entry ahead of it. There is a maximum of six total positions.

    Insert new after this one

    Pushes all of the following sequences down one position and creates a new, empty entry just after the displayed entry. There is a maximum of six total positions.
