Inspection Tools

The Conditions panel also contains two checkboxes and two buttons, which
are described briefly, as follows:
•
Enable –– The Enable checkbox is used to enable or disable the
corresponding inspection tool. The tool is enabled when a check mark (
√)
appears in the checkbox, and is disabled when the box is empty. The
selection can be changed to its opposite state by picking the box
alternately.
•
Invert –– The Invert checkbox is used to enable or disable the invert
function for the selected condition (input or tool result). The invert
function is enabled when a check mark (
√) appears in the checkbox, and
is disabled when the box is empty. The function can be changed to its
opposite state by picking the box alternately.
When the invert function is enabled, the “condition” will be satisfied
when its opposite state is asserted; thus, if
Tool 1 – Pass is the selected
condition, as shown in Figure 7.147 (page 7–183), and Invert is enabled,
the condition will be satisfied when the opposite state (that is, Fail ) is
present. Similarly, if input In1 is the selected condition and Invert is
enabled, the condition is satisfied when In1 is inactive. Further, if Zero is
the selected condition with Invert enabled, the condition is satisfied when
a non–zero condition occurs.
•
Done –– Use the button to save the highlighted condition and exit
the Conditions panel.
•
Cancel –– Use the button to exit the Conditions panel without
saving any newly selected conditions.
Figure 7.148 and Figure 7.149 provide an example inspection that illustrates
the concept of conditional processing. Figure 7.148 shows a toolset edit
panel containing one window tool and eight gage tools. The window tool and
four of the gage tools receive their image from
C1 (camera #1), while the
other four gage tools receive their image from C2 (camera #2).

(Note that a toolset edit panel can display only eight tools at one time; thus,
the ninth tool in this example is shown separately, below the first eight tools.)
