Quick Reference Manual

Schematic Symbol Naming Convention
Default Family Codes
 The first character is either "H" or "V" for horizontal or vertical wire insertion.
 The next two characters are reserved for family type (for example, PB for
push buttons, CR for control relays, LS for limit switches).
 The fourth character is generally a 2 for child contacts and 1 for everything
else (parent or standalone component).
 If the symbol is a contact, then the fifth character is a 1 for normally open, 2
for normally closed.
 The remaining characters are not specified. They are used to keep names
unique. Symbol names are limited to 32 characters.

Replaceable Parameters
Replaceable parameters are codes used to define tagging formats.
Device tags, wire numbers, cross-reference parameters:
%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
Wire annotation and graphical terminal strips parameters:
%P: Terminal pin text
%Q: Terminal pin TERMDESC text
%I: IEC-style installation code
%L: IEC-style location code
%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.
%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)
Note: You can use only one of the (%number) parameters.
