3. Objectives Extend the Object present verification system to include a dimension control system and learning the following:
Understand the Scorpion reference system
Do measurements using the RadialArcFinder tool
Optimising analysis time

SL c Getting Started Exercise Part 2

4. Find Inner Radius The task is to find and measure the inner radius
Add RadialArcFinder toll and name it ”FindInnerRadius”
SL c Getting Started Exercise Part 2

5. Using another Tool as a Reference
Using a another tool as a reference is a very strong feature
In Part 1 scaling was used as a reference to convert pixel to mm
Here we use the tool ”FindObject”
The result is that centre X,Y now is identical to centre of gravity of the blob
Check that the pointer info show 0,0 at the centre of the blob

6. RadialArcFinder - Setup
Set angle step to 10 – search line for each 10 degrees
Inner radius to 0 – search lines start from centre
Outer radius to 8 – search lines stop at 8 mm

7. RadialArcFinder - Visualisation
Click on visualisation and mark the following:
Circle
FittedPoints
ROI
TraceLines
SL c Getting Started Exercise Part 2

8. RadialArcFinder Advanced
In advanced a number of different parameters can be set
We will focus on Edge Detection – some of the other parameters will be explained later in the course or please refer to the help function
Set the polarity to ”LightToDark”
SL c Getting Started Exercise Part 2

9. RadialArcFinderResults
Under the result you will find the measure of the radius. Since the basic reference here is the tool scaling, the result is in millimetres.
To add the unit, mark the radius, left click, select unit and write mm

10. Analysis time
In the tool box you will find a column for Analysis time (adjust the columns if necessary)
Read the analysis time for the FindInnerRadius tool
SL c Getting Started Exercise Part 2

11. Increasing number of trace lines
Open the FindInnerRadius tool and adjust the angle step to 1. This means that there is a search line for each degree – 10 times more search lines
Observe the change in analysis time
When inspection time is critical, this feature can be used to optimise the tool
SL c Getting Started Exercise Part 2

12. Inner radius - classification criteria
To establish the criteria use a logic tool and name it ”InnerRadiusOK”
SL c Getting Started Exercise Part 2

13. Setting the criteria conditions
Find the tool and the parameter that should be tested
Tool = FindInnerRadius
Parameter = Radius
Click OK and Apply. The parameter value and check the result
SL c Getting Started Exercise Part 2

14. Create FindOuterRadius by copying
Mark ”FindInnerRadius” tool, right click and select copy
Mark the last tool in the tool box, right click and select paste
Change the name to FindOuterRadius
SL c Getting Started Exercise Part 2

15. Setting parameters
All the parameters copied and must be changed to find the outer radius
Enter the following
Inner Radius = 7
Outer Radius = 15
Edge detection = DarktoLight
SL c Getting Started Exercise Part 2

16. Final result
SL c Getting Started Exercise Part 2

17. Setting criteria for outer radius OK
Create a the logic tool for classification of the outer radius result either by copying or by New.
Remember to find the right tool, parameter
Set the conditions to min = 9.7 and max = 9.9
SL c Getting Started Exercise Part 2

18. Radius OK
Finally we want to create a logical classification called RadiusOK
It combines inner and outer radius classifications. This tool is true (value =1) when both inner and outer radius is OK
Remember to check that ”AND” is marked.
If ”OR” is marked the logical value of the tool will be true if only one of the conditions are true
SL c Getting Started Exercise Part 2

19. Modifying the OK condition
To include the Radius OK condition in the OK condition under Settings – do the following:
Open the OK condition
Click on New and add the RadiusOK parameter
Check that AND is marked
Now OK only will occur when both the object is present and the radius is OK
SL c Getting Started Exercise Part 2

20. Adding a Radius Fault condition
Copy the OK condition and name it ”FAULT”
We can use the RadiusOK classification to define the Fault condition by inverting the result
Fault will now only occur when both the object is present and one or more radius is fault
Remember to select background colour RED
SL c Getting Started Exercise Part 2

21. Check all conditions
Tip: Change the colour for the No Object condition to yellow to differentiate from the red Fault condition
SL c Getting Started Exercise Part 2

22. Displaying measurement values
Any results from any tool can be displayed in the result panel
We want to display the inner and outer radius
Position the mouse inside the result panel and right click, select ”General”, ”No of measumentvalues” and enter 2 for 2 values
Check the result panel
SL c Getting Started Exercise Part 2

23. Selecting parameters to be displayed
Position the mouse over Tagvalue 1 and right click, select Measured Values, Parameter.
In the new dialog box click the ”..” button.
In the new dialog box you can select the tool and the parameter you want
Select the tool FindInnerRadius and the parameter Radius
SL c Getting Started Exercise Part 2

24. Add name and unit to the value
Position the mouse over Tag Value 1, right click, select Measured Values and Caption.
Enter the name ”Inner Radius”
Through the same procedure you can add unit (mm) and change the number of decimals
Repeat the procedure for displaying the outer radius as Tag Value 2 and name it ”Outer Radius”
SL c Getting Started Exercise Part 2

25. Displaying sub results
The sub result from logical classification in the tool box can be displayed on the Indicator panel
First you have to activate the Indicator Panel under ”General”
Position the mouse over the panel and right click, select ”General” and No of Columns”
We want to display the sub results from testing the inner and outer diameter, therefore enter 2 (columns)
SL c Getting Started Exercise Part 2

26. Final result and indicator panel
Using the technique described before enter names and related parameters for both indicator panels
You can also change colours for the different conditions
SL c Getting Started Exercise Part 2

27. Modifying the Send Status RS232
In part 1 we configured the SendStatus command to be sent after every inspection (1 = object present and 0 = object absent)
We know want to change the status to a 2 bit code XY
X = Object presence (1) or absence (0)
Y = OK = 1 and FAULT = 0 using the Radius OK logical classification
Remember to separate the two parameters with a comma
SL c Getting Started Exercise Part 2

28. Checking the communication
SL c Getting Started Exercise Part 2

29. Sending measured data to an external system
The measured data (inner and outer radius) can also be sent i.e. over the RS232 to an external system
This can easily be implemented adding a new RS232 command under the event ”Inspection”
SL c Getting Started Exercise Part 2

30. Using the Guard function
In this case we only want to send data when the condition is OK, since data in the FAULT and NoObject conditions will disturb the statistics
Using the Guard function a command or a tool only will be active when the guard is true
In this case we can use the logical classification ObjectPresent as a guard
Therefore only when ObjectPresent is true the data will be sent
SL c Getting Started Exercise Part 2

31. Testing communication with the Guard function
When the first status bit is 0 (Object absent), no data is sent.
SL c Getting Started Exercise Part 2

32. Logging Data You can add as many parameters to be logged.
All data will be saved in a file
Set up the system to log the inner radius and outer radius
SL c Getting Started Exercise Part 2

33. Configure data logging
Click on ”Setup” and you can configure the logging:
File name
Folder
Operator input
Remember to Activate the logging function
