9.4 Remote Teach

This section explains teaching inspections on good product using Remote Teach.

9.4.1 Understanding Remote Teach

The Remote Teach function is a method of remotely updating inspection parameters in Run mode. Vision tool(s) and

Test tool(s) can each be selected to be taught. To remotely teach an inspection, the Remote Teach function must be

enabled on each tool to be taught.

Note:

The Location tools, the Measure tool, and the Communication tool are not affected by Remote Teach.

The sequence of events in the sensor is as follows:
1. With the sensor in Run mode (and Ready), pulse the Remote Teach line (Pin 2, gray wire).
2. The sensor recognizes that the Remote Teach line is active and waits for the next valid trigger.
3. At the next valid trigger, Ready goes inactive (the Green Ready LED shuts OFF), and the sensor acquires a new

image.

4. The sensor adjusts the ROI (if the inspection uses Location tools).
5. The Vision tool learns the new pattern and performs the analysis.
6. The sensor adjusts the minimums and maximums in the Test tool (if the Test tool is enabled for Remote Teach).
7. The inspection indicates Pass if the pattern meets the requirements of the Vision tool and (if the Test tool is enabled

for Remote Teach) if the evaluation of the Test tool(s) passes with the adjusted minimums and maximums.

8. The inspection will Fail if the Vision tool(s) or the Test tool(s) fails. If the inspection fails, another Remote Teach

sequence or user intervention is required.

9.4.2 Remotely Teaching a Tool

To remotely teach a tool, the user must enable Remote Teach on each tool to be taught. This can be accomplished by

clicking on the Enable Remote Teach box in the tool window before running an inspection (typically performed when

the inspection is created).
To perform a Remote Teach, do the following:
1. Verify that the correct tools are enabled for Remote Teach.
2. Verify that the sensor is in Run mode.
3. Verify that the Green Ready LED is ON.
4. Activate the Remote Teach input.
5. Position the target as desired.
6. Trigger the Sensor.
Following a Remote Teach, subsequent inspections will be performed with the newly learned parameters of the Vision

tool(s) and the Test tool.

Caution:

A successful Remote Teach will occur ONLY if the new target is similar in contrast to the original

target. The exposure time and gain are NOT modified during Remote Teach.

9.4.3 Timing Sequence

The timing for the Remote Teach sequence is shown below (the diagram assumes Remote Teach is enabled on the

tools and that all signals meet minimum times).
It is important to note that the remotely taught parameters are not saved to non-volatile memory; hence, the remotely

taught inspection is good only as long as Run mode is maintained and power to the Sensor is not lost.
