■ The next two characters are "W0." A zero (0) means that the symbol does
not trigger a wire number change through it.
■ The fourth character is either 1 or 2: "1" for parent marker or "2" for child
marker.
■ The remaining characters are not specified.
Examples:
Parent cable conductor marker, horizontal wire insertionHW01.dwg
Child cable marker, horizontal wire insertionHW02.dwg
Parent cable conductor marker, vertical wire insertionVW01.dwg
Child cable marker, vertical wire insertionVW02.dwg
Components - General
Schematic components such as relays, switches, pilot lights, and discrete motor
control devices (but not PLC I/O symbols) follow this naming convention:
■ 32-character block name maximum, 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). A zero (0) as the
second character of the family type (for example, a 0 in the overall symbol
name) means that the symbol does not trigger a wire number change
through it. (For example, T0 for terminals, W0 for cable markers, C0 for
connectors.)
■ The fourth character is generally a 1 or a 2: 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.
