5. 5 Create a profile from an archive file 1. Open Scorpion and click on restore 2. Select Getting Started_Start.zip 3. The ”Getting Started” profile is installed

6. 6 Create a new Profile - 1 1.Select ”New” 2.Give it a name ”XYGettingStarted” where XY is your initials This profile is almost empty and is ideal if you want to start from scratch

7. 7 Create a new profile - 2 You can copy the content of an existing profile to automatically add functionality to the new profile 1.Mark the profile called ”GettingStarted” and select copy 2.Select copy to the new profile ”XXGettingStarted”

8. 8 Starting point Operation mode: (No password) –For operators –Can start and stop the inspection –Read history list, curves and statistics –No access to any configuration Settings mode: (Password: 1234) –For operators certified to adjust certain parameters, alarm limits and logic states Service mode: (Password: 911) –Full access to all functions Enter Service mode by pressing the service button and enter the password

9. 9 File as an image source 1.Simulation ON 2.Click on Snapshot 3.Check the image catalogue if no image on screen \Scorpion_200\GettingStarted\Images 1 2 3

10. 10 Show Info on the image With the cursor on the image right click the mouse and select ”Show info” from the menu X and Y number are pixel position, origo (X=0 and Y=0) is in the upper left corner Pixel value is the greyscale value (0 = Black, 256 = White)

11. 11 Zoom the image Press the left button on the mouse and mark the zoom area Release the button and the image is zoomed in Click on the image to zoom out

12. 12 Operating the Tool Box 1.Go to the Toolbox and click on New 2.Give the Tool a Name For easy understanding of the task for this specific tool – use names 3.Select a Tool 4.Use help to get information about the tool 1 2 3 4

13. 13 Create a tool - Scaling 1.Name the tool - Scaling 2.Select the tool ”ScaleReference” Use help if you want information about the tool 3.Click OK

14. 14 Using a Tool - 1 GENERAL Show the name and type of tool. Comments can be entered in the description field SETUP For entering parameters controlling the tool

15. 15 Using a Tool - 2 VISUALISATION For adding graphics on the image, visualising the operation of the tool All or this tool only visualisation, can be selected RESULT Displaying all the results from the operation of the tool

16. 16 Image used for scaling In the catalogue Scaling there is an image with millimetre indicators Go to ”Camera” and select the correct directory “Scaling” under Image Setting

17. 17 Scaling image on the screen

18. 18 Manual measurement on the image When the mouse is positioned over the image right click to get the menu Select ”Show info” and then ”Measure” Measurements can now be done from the pixel origo point (0,0)

19. 19 Measure distance in pixels The distance is measured in pixels To set a new origo position the mouse directly on the new origo (use zoom if necessary) Then right click to get the menu and select ”Set origo” TASK: Measure how many pixels there are in 50 millimetres

20. 20 Configuration of ScaleReference If the number of pixels are 480, then we can calculate the parameter to be entered for X and Y 480 pixels/50 mm = 9.6 Look at the result from the tool – it is the pixel resolution of the image (1 pixel = 0.10 mm)

21. 21 Visualisation and scaling

22. 22 Saving and storing Saving configuration –Pressing Profile button –Each time you press the Start button –Each time you close the application Archiving a profile –Select ”Maintenance” –Press ”Backup” button and follow instructions

23. 23 Changing back to image catalogue Select ”Camera” and set the image catalogue back to ”Images” Press ”Snapshot” to verify that you get the correct images

24. 24 Start and Stop of Inspections Automatic inspection Pressing ”Start” button set Scorpion in Running mode For every new image an inspection is automatically executed The image can either be triggered from an external system or from an internal scheduler Pressing the ”Stop” button stop the process Manual inspection –Pressing ”Snapshot” button grab a new picture –Pressing ”Inspection” button execute the inspection –Pressing ”Snapshot” button again will grab another new picture.

25. 25 Scheduler For setting up tasks running at scheduled intervals The task ”Trigger” is configured to grab an image every 1000 ms When ”Start” button is pressed a new image is grabbed every 1000 ms By pressing edit you can adjust the time interval

26. 26 Using a Blob to locate the object Add a new tool in the toolbox: –Name= FindObject –Tool = BlobTool

27. 27 Using Reference in a tool Select Scaling as parameter in the Reference box and click on ”Apply” Show info on the image mm coordinates are now used in this tool

28. 28 ROI – Region of Interest Each tool can must be configure to search in a specific area on the image (Range of Interest – ROI) Move the mouse to the centre of the image and read the X and Y coordinates. Enter the co-ordinates and specify the delta X and delta Y values The ROI visualisation is shown on the picture

29. 29 Understanding the Blob tool A blob search for areas in the specified ROI with greyscale values within a given range Place the mouse on the object and read the greyscale value If the maximum Threshold is set to higher value and the minimum to a lower, the Blob tool will find the object

30. 30 Apply your configuration To apply a new parameter set by you, the button apply must be pushed You can also set minimum an/or maximum requirements to the blob area to be located

31. 31 Blob visualisation Through the visualisation you can see how the tool works on the image Activate only CenterofGravity, MaxContour and ROI Remember to push ”Apply” before you see the result!

32. 32 Blob result Check the result of the blob tool. Here you can find the number of blobs, individual blob areas and ”Holes”

33. 33 Holes in a Blob A Hole is an area inside a blob with greyscale values outside the max and min values set in the blob tool

34. 34 Application of using holes Counting the dice

35. 35 Avoiding false alarms In a real control system situations may occur where the system will not recognise an object or cannot do the configured measurement. Consequently, a vision control system should be prepared and configured for such situations in order to operate properly In our example we know that it may occur that no object is present Therefore we want to establish a logical classification of Object Present

36. 36 ObjectPresent – logical classification To establish a logical classification we use the Logic Tool Push ”New” and name it ”ObjectPresent” and select ”LogicTool”

37. 37 Configuring a Logic Tool We can use the size of the blob area as the classification parameter Push Edit and select the ”FindObject” tool and select the blob(0) area Click OK and Apply, you will now see the value of the actual blob area Click Edit again and set the minimum area to i.e. 100

38. 38 Checking the ObjectPresent tool Select the result panel and go through all images and check that the result is correct Object present should give Value = 1 Object absent should give Value = 0

39. 39 Configuring the User Interface In Settings mode we can define the Logical States the system shall communicate to the user and to the process control system The valid logical state after an inspection is displayed in the Result Panel

40. 40 OK condition - Object Present Double click on the existing OK state Now you can enter a new name, description and select the colour for display in the result panel

41. 41 Defining the OK (Present) condition Click on ”Constrains” and ”New” The box shows a list of all available logical classifications in the Toolbox Select ”ObjectPresent” The OK condition is now true when the logical classification ”ObjectPresent” is true (=1)

42. 42 Testing the OK condition Run through all pictures and check the result of the condition (true or false) and the display on the result panel When no object occur the result panel display ”Undefined Condition” since no condition for NoObject is yet defined

43. 43 Adding a NoObject Condition Click on ”New” for adding a new condition Name it ”NoObject” Select Red as background colour (when this condition is true the result panel will be red)

44. 44 Configuring the NoObject condition To define the NoObject condition we can use ObjectPresent Logical classification Click on ”New” and select ”ObjectPresent” To make the NoObject condition true when the logical classification ObjectPresent is false, we invert the statement by pushing the invert button

45. 45 Testing NoObject State Run through the pictures and check: –the result of the both conditions (true or false) –The colour and text in the result panel

46. 46 History list In the Operation Mode you will find the History list The history list contain the picture an all result from the inspection You can configure the list by right clicking the mouse

47. 47 Statistics In Statistics you find the result of current period and previous period. The statistics use the logical conditions By right clicking the mouse the statistics can be configured

48. 48 Scorpion Events All processing in Scorpion are managed through ”Events” For each Event one or more commands will be executed New Events and Commands can be configured by the user A more detailed description of Events are found in part 2

49. 49 Sending Status data to a PLS We want to send status data (object present or absent) using the RS232 interface We will link the timing of sending the data to the event ”Inspection” Initially the event inspection activate the command ”Inspect”. After that we want the system to send status data

50. 50 Adding a RS232 command In command sequence for Inspection click on ”New” Select ”RS232Cmd” Name the command ”SendStatus”

51. 51 The command protocol Syntax ”Text” %dparameter –Text = user defined text –%d = format instruction for the result value (1 digit) –Parameter = The parameter description of the result from any of the tools in the toolbox To find the parameter description of the result push the ”Parameters” button on the top toolbar Select ObjectPresent and Value and click on the copy button

52. 52 Writing the command protocol Open the SendStatus command In the Parameter field write the following –Status=%d Place the cursor after the d and paste (right click the mouse) Status=%dObjectPresent. Value

53. 53 Testing the communication Mark the SendStatus command Push the Execute button – Now the command is run once In ”Communication” select RS232 - here the out messages are logged Check that the correct status value is sent

54. 54 Testing the Scorpion Profile Activate automatic inspection (push Start) and check that the status value sent over RS232 is correct for each inspection
