8.9.5 Using Remote TEACH with the Match Tool
If
multiple
Match tools are used in the same
inspection,
remote TEACH teaches all Match tools at the same
time
using the same trigger.
The
time
to teach is included in the
inspection
time
on Tools & Results and All Results.
1. Set up the
inspection
and Match tool(s) as desired.
2. In Vision Manager, make sure that one of the
five
user-defined
I/O is set to Remote Teach.
3. Toggle the Remote Teach input. The next valid trigger input causes the Remote Teach to occur. This is when the new Match
patterns
are learned.

Object Tool
Use the Object tool to detect and measure the length of dark and bright segments in an ROI.
The Object tool measures the widths of every dark and light segment along the ROI, calculates the midpoint for every segment, and
counts the total number of segments. The midpoint
location
can be used as an input to the Measure tool. Each segment can have a
unique size limit, or all segments may have the same size limit.
Example
applications:
• Measure the width of a label
• Locate the center of a box on a conveyor
• Measure the gaps between stamped metal parts
