Set up peer-to-peer component relationships
The following example has a valve representation on
an instrument drawing, FE100, and its equivalent on
the electrical schematic, SOL2500. They are the same
physical device, but carry different tags based on the
drawing discipline in which they appear. Though
each device is represented as a parent symbol, you
can set up a peer-to-peer relationship between them
so that the electrical tag name of the schematic
automatically cross-references to the instrument
drawing, and the tag cross-references of the instru-
ment bubble to the tag of the schematic.
The instrument bubble symbol is set up with an op-
tional split tag. Instead of a single TAG1 attribute, it
has two tags: TAG1 PART1 and TAG1 PART2. The
instrument bubble is also set up as a normal AutoCAD
Electrical parent schematic symbol without the wire
connection points. It includes two extra attributes
beyond what a normal parent symbol carries:
WDTAGALT - carries a copy of the schematic
TAG1 value of the symbol.
WDTYPE - an invisible attribute with a nonblank
value indicating the component category. Ex-
ample: "PI" for P&ID, "PN" for pneumatic, or "HY"
for hydraulic
