■
The next 2 characters are the first 2 letters of the family name (for example,
GV for diaphragm valves, IN for instruments, N for nozzles). See
Overview
of Hydraulic and P&ID symbols
(page 174)for a list of symbol family names.
■
The 4th character is "1" for P&ID symbols - stand-alone component.
■
Use "_" and enter a meaningful name corresponding to the symbol.
Example:
Vertical standalone cyclone; ver_tank is the meaningful
name for the symbol
VTK1_ver_tank.dwg
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.
Parametric Twisted Pair Symbols
A parametrically generated twisted pair representation consists to two instances
of the same symbol (there are no parent/child versions). This symbol must
carry attribute ACE_FLAG with a value of "3." Parametric twisted pair symbols
follow this naming convention:
■
The first 4 characters are "HT0_" or "VT0_" for horizontal or vertical
parametric symbols.
■
The remaining characters can be anything (default is set to "TW")
Examples:
Horizontal parametric connector symbol
HT0_TW.dwg
Vertical parametric connector symbol
VT0_TW.dwg
PLC I/O Parametric Build Symbols
These symbols begin with "HP" or "VP" (horizontal rung versus vertical)
followed by a digit 1 through 9. The digit corresponds to the selected PLC
module style or look (1 through 5 are provided in the AutoCAD Electrical
library, 6 through 9 can be user-defined).
