The Drawing Properties dialog box makes use of codes as replaceable parameters that are encoded on to attributes of the invisible WD_M block of the drawing. For example, if you set your component tag format to be %F%N, this format is encoded on to the TAGFMT attribute of the WD_M block. When AutoCAD Electrical toolset assigns a TAG to a component, this format is read and the codes are replaced with the appropriate values.
Replaceable parameters are also used for device tagging, cross-referencing, wire numbering, wire annotation, and graphical terminal strips.
Defined in the Drawing Properties.
| %F | Component family code string (for example, "PB," "SS," "CR," "FLT," "MTR") |
| %S | Sheet number of the drawing (for example, "01" entered in upper right) |
| %D | Drawing number |
| %G | Wire layer name |
| %N | Sequential or Reference-based number applied to the component |
| %X | Suffix character position for reference-based tagging (not present = end of tag) |
| %P | IEC-style project code (default for drawing) |
| %I | IEC-style installation code (default for drawing) |
| %L | IEC-style location code (default for drawing) |
| %A | Project drawing list's SEC value for active drawing |
| %B | Project drawing list's SUB-SEC value for active drawing |
The %L and %I values used for cross-referencing are the Drawing Default Location and Installation values from the corresponding Parent or Child drawing and not the Location and Installation values of the component itself.If you have a Parent on a drawing that has a default Location of “M” and its child is on a drawing that has a default Location value of “MC,” the cross-referencing on the parent shows the “MC” (drawing default location value of the drawing the child is on) and the child shows the “M” (drawing default location value of the drawing the parent is on) no matter what the location value is on either the parent or child.
Example of Component Tags
(For relay number 50 on sheet 3)
%F%S%N = CR350
%F%N = CR50
%F-%S-%N = CR-3-50
(For 3 push buttons on line reference 101 using reference-based tagging)
%F%N = PB101, PB101A,PB101B
%N-%F = 101-PB, 101-PBA,101-PBB
%N%X%F = 101-PB, 101A-PB,101B-PB
Example of Wire Number Formats
(For wire number 50 on sheet 3)
%S/%N = 3/50
%N = 50
W-%S%N = W-350
| %P | Pin number of the component connected to the terminal |
| %Q | Terminal pin TERMDESC text |
| %I | IEC-style installation code of the component connected to the terminal |
| %L | IEC-style location code of the component connected to the terminal |
| %M | Mount assignment (on panel footprint equivalent) |
| %U | Group assignment (on panel footprint equivalent) |
| %W | Wire number |
| %C | Cable tag + conductor/core color combination (format is "tag-color") |
| %E | Cable tag |
| %J | Cable conductor/core color |
| %V | Cable tag substituted for wire number if cable tag is non-blank.
The wire number is displayed when a cable ID does not exist. |
| %G | Wire color/gauge (or wire layer name) |
| %H | Cable wire color substituted for wire number if cable color is non-blank.
The wire layer is displayed when a wire conductor in conjunction with a cable ID does not exist. |
| %T | Terminal strip terminal pin assignment |
| %K | Terminal strip TERMDESC text - useful for multi-stack terminals |
| %1 | Destination component tag ID. You can use only one of the (%number) parameters. |
| %2 | Equivalent of "%1:%P" (comp tag:term) |
| %3 | Equivalent of "%1:%P:%D" (comp tag:term:termdesc) |
| %4 | Equivalent of "%L%1" (IEC comp tag) |
| %5 | Equivalent of "%L%1:%P" (tag:term) |
| %6 | Equivalent of "%L%1:%P:%D" (tag:term:termdesc) |
| %7 | Equivalent of "%I%I%1" (INST prefix+IEC comp tag) |
| %8 | Equivalent of "%I%L%1:%P" (tag:term) |
| %9 | Equivalent of "%I%L%1:%P:%D" (tag:term:termdesc) |
The part after the colon(:) is suppressed if the value is blank in %2 - %9 parameters (for example, %2=comp tag:term). The ":term" part is suppressed if blank.
