■ Break into the one-line bus where the circuit connects.
On a dual circuit one-line template, there are three bus-tap symbols. One at
the normal point where the circuit ties into the bus. There is another version
of the symbol on each of the two circuit "legs", each marking the point where
that part of the dual circuit starts. These bus-tap symbols allow various reports
to report accurately on a one-line circuit, whether a single circuit or a dual
circuit representation.
The following bus-tap symbols are supplied:
■ HDV1_BT_1-.dwg - with “dot” for horizontal one-line circuit
■ VDV1_BT_1-.dwg - with “dot” for vertical one-line circuit
■ HDV1_BTT_1-.dwg - “tee” connection for dual horizontal circuit
■ VDV1_BTT_1-.dwg - “tee” connection for dual vertical circuit
■ HDV1_BTL_1-.dwg - “corner” connection for dual horizontal circuit
■ VDV1_BTL_1-.dwg - “corner” connection for dual vertical circuit
NOTE A WDTYPE attribute with a “1-1” value, identifies a bus-tap symbol.
P&ID Symbols
The maximum number of characters for the block name is 32.
■ The first character is "H" or "V" for horizontal wire or vertical.
■ The next two characters are the first two 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 on page 304 for a list of symbol
family names.
■ The fourth character is "1" for P&ID symbols - stand-alone component.
■ Use "_" and enter a meaningful name corresponding to the symbol.
