H. CONTROL DRAWING BUILDER
H.5.1 WIRING METHOD
Wiring is displayed with an arrow to indicate the flow of data between two
function blocks or between a function block and a data link block. The three
methods for drawing wiring are shown below:
♦ Automatic wiring
♦ Manual wiring
♦ All wiring
With automatic wiring and group wiring, the property of the wiring drawn is set as
“automatic.” With manual wiring, the property is set as “manual.” Whether the
wiring can be edited or not is determined by its property. Also, there are forward
wiring and backward wiring; these two types of wiring are displayed differently in
the drawing pane. Forward wiring the means wiring follows the control sequence
in the control drawing. Backward wiring means the wiring runs in the reverse
direction from the control sequence.
[All wiring] may be used to convert the wiring information when changing the
builder for editing the control drawing created on the function block overview
builder, from the function block overview builder to the control drawing builder.
H.5.2 AUTOMATIC WIRING
To connect blocks with auto wiring, perform one of the following operations.
♦ Select [Wiring] on the [Insert] menu.
♦ Click [Wiring] button at the toolbar.
Wiring icon
Specify two points representing an output connection terminal and an input
connection terminal of block symbols in the drawing pane. The wiring route is
automatically determined and the wiring is drawn. The color of the wiring is
purple.

With automatic wiring, the wiring route is determined in accordance with the
following rules:
♦ Two wiring lines both in the horizontal direction or in the vertical direction
do not overlap with each other.
♦ With the exception of block comments, no object cuts across the block
area.
