Blocks that define a wire number to assign to the wire under the block.Wire Number
Blocks that define the placement of a branching or nested circuit such as a control
circuit at the insertion point of the marker block.
Nested Circuit
Blocks that define the placement of a component, connector, terminal, cable marker,
or a multi-pole component at the insertion point of the marker block.
Component
Blocks that control rung spacing adjustment for the wires under these blocks. Blocks
that are processed as a group must carry common CODE and ORDER attribute values.
Bus Spacing
Blocks that control stretching a wire segment to connect to another wire.Wire Connec-
tions
NOTE The name of the marker block cannot be changed. The Circuit Builder
command only processes marker blocks named "ace_cb_marker_block".
One-line circuit templates
One-line circuit templates use the same marker block concept as three-phase
motor and power feed circuit templates. However, there are a few differences.
There is a single line wire that represents a multi-wire bus. Most of the one-line
circuit templates contain a special "bus-tap" symbol.
The bus-tap symbol can have two functions:
■ Provide an anchor point for the one-line circuit representation that begins
at this location.
■ Break into the one-line bus where the circuit connects.
On a dual circuit one-line template, there are three of 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
