PLC I/O Parametric Build Symbols These symbols begin with "HP" or "VP" (horizontal rung versus vertical) followed by a digit 1 through 9. Panel Layout Footprint Symbols There isn’t a required naming convention to follow, but the name must adhere to the AutoCAD 32-character block name limit. Horizontal cable marker, no wire number change through it Vertical push button, child contact, N.O. Vertical push button, parent contact, N.O. They are used to keep names unique.Ĭontrol relay coil, horizontal rung insertionĬontrol relay coil, vertical rung insertion The remaining characters are not specified. If the symbol is a contact, the fifth character is a 1 or 2. 1 = parent or stand-alone components 2 = child contacts The fourth character is generally a 1 or 2. A zero (0) as the second character of the family type means that the symbol does not trigger a wire number change through it (for example, T0 for terminals, W0 for cable markers, and so on). The next two characters are reserved for family type (such as PB for push buttons, CR for control relays, or LS for limit switches).
General Components Schematic components such as relays, switches, pilot lights, and discrete motor control devices (but not PLC I/O symbols) follow this naming convention: ■ģ2 character block name maximum the first character is either “H” or “V” for horizontal or vertical wire insertion. Red in-line marker, horizontal wire insert The first character is “H” or “V” for horizontal wire or vertical wire insertion. In-line wire marker symbols follow this naming convention: ■ This can be very small but it needs to be present for AutoCAD Electrical to correctly see the in-line inserted block as it traces the wire network. NOTE The ladder line reference block used by AutoCAD Electrical is determined by the ladder reference configuration selected in the Referencing tab on the Drawing Configuration dialog box.ĭumb In-Line Wire Marker Symbols Dumb in-line wire marker symbols must be constructed with a tiny piece of "pigtail" line entity at each connection point. This symbol name is used by AutoCAD Electrical when you select ‘User Block’ from the Referencing tab on the Drawing Configuration dialog box.
Optional, user-defined alternative to WD_MLRH.dwg. Same as above but for a ladder that lies on its side. These carry the drawing’s settings for panel layout functions.īlock insert that carries a ladder’s first line reference number and additional information such as rung spacing and ladder length. Optional block insert consisting of several invisible attributes. Parent cable conductor marker, vertical wire insertionĬhild cable marker, vertical wire insertionĬomponent Location Mark Symbols AutoCAD Electrical expects the location symbol names to begin with the characters “WDXX.”Ĭonfiguration and Ladder Master Line Reference Symbols AutoCAD Electrical expects to find these block inserts: WD_M.dwgīlock insert consisting of about 50 invisible attributes. Parent cable conductor marker, horizontal wire insertionĬhild cable marker, horizontal wire insertion The next two characters are “W0.” A zero (0) means that the symbol does not trigger a wire number change through it. The first character is “H” or “V” for horizontal or vertical wire insertion. These are referenced by AutoCAD Electrical and its icon menuing system and are inserted as standard AutoCAD blocks with attributes.Ĭable Marker Symbols AutoCAD Electrical cable conductor marker symbols follow this convention: ■ Library Symbol Naming Conventions The default symbol subdirectory, jic1, and a companion 0.125 uniform text height library, jic125, each contain many hundreds of component symbols in standard AutoCAD ".dwg" file format. The following pages describe the naming conventions that should be followed when you create or modify library symbols.
