Setup Chapter 4 4.1 Setup Screen The Vision sensor has two modes: running and idle. If the sensor is idle when you start up the PresencePLUS software while your PC is connected, the software starts in the Setup screen. If the sensor is running, then the software starts in the Run screen. 4.2 Capturing a Reference Image The reference image is used as a template for developing an inspection. The Vision tools use this image to acquire the critical information needed for the inspection.
Setup 2/2010 4.3.1 Reference Image Source Before capturing an image, you need to determine what will trigger the Sensor to capture and image. The Sensor can be triggered to capture an image in one of the following ways. Trigger Option Description Continuous The sensor will update continuously in Setup mode. 28 Minneapolis, MN USA Banner Engineering Corp.
2/2010 Setup Trigger Option Description External Images are acquired only in reponse to a signal from an external source as configured on the Trigger tab. Choose External if the part will be moving during the inspection to capture an image with the same conditions as the inspection conditions. Manual Images are acquired only then the Trigger button is clicked. The Trigger button is grayed out when any trigger option other than Manual is selected.
Setup Field 2/2010 Description • Image too bright -- Auto exposure could not darken the image enough. Remove light to the inspection, or decrease the exposure manually. Exposure Time Exposure time is the amount of time the camera allows light to energize the image chip. Increasing the exposure time (that is, moving the slider to the right) allows more light to energize the image chip, which brightens the image. Gain Gain is an electronic boost to the image signal.
2/2010 Setup 4.4.1 Trigger Settings Field Description Trigger Divide (range: 1-10,000 triggers) Sets the sequence of valid triggers. If set to 1, an image is captured in response to every valid trigger; if set to 2, and image is captured in response to every second valid trigger, and so on. Trigger Delay (range: 0-8,000 ms) Fixed time (ms) from the instant the Sensor receives a valid trigger to the instant the Sensor captures the image.
Setup 2/2010 4.5 Advanced Tab The Advanced tab on the Setup screen allows you to adjust the field of view (FOV). The FOV is the image area at the focal plane of a camera. You can use the maximum FOV or adjust the FOV to improve performance. The FOV dimensions are shown in the Advanced tab. Default Mode The Default Mode determines whether to use the Current FOV or Maximum FOV by default. Maximum and adjusted FOV The FOV is denoted by the green box surrounding the image in the Setup screen.
2/2010 Setup 4.6 Considerations When Setting up Color Inspections 4.6.1 Primary Colors A color Vision sensor has a color imaging chip that, rather than providing just a gray scale value along with the grid location, actually provides a color intensity value for each of the primary colors of light: red, green, and blue. Variations of color intensity for each of these primary colors provides all other shades of colors. Banner Engineering Corp.
Setup 2/2010 Red, Green, Blue (RGB) Red, Green, and Blue (RGB) is a representation of additive color space where red, green and blue are combined to create other colors. This is the primary method for showing color on monitors and televisions. The RGB color space is represented as a cube with the three primary colors whose axes are perpendicular to each other. Black is the absence of all primary colors; that is, the intensity of all three primary colors is zero [0,0,0].
2/2010 Setup Practically speaking, auto-exposing in this way ensures that the camera is kept in the optimum range of the R-G-B scale. White Balance White balancing is the process by which a color imager is calibrated for existing lighting conditions. Due to the large variation in light sources and the fact that the R, G, and B channels on the imager are analyzed independently, a color sensor just out of the box may not have a true color image initially.
Setup 2/2010 Draw the WB ROI on a region of the image known to be white. This routine will automatically adjust the gain for each of the R, G, and B channels in an effort to make the area in the WB ROI appear white. Strange effects can occur if the area in the WB ROI is not in fact white as shown below when white balancing on blue. This effects will carry over to the gray scale version of the image too. 36 Minneapolis, MN USA Banner Engineering Corp.

2/2010 PresencePLUS Software Tools Field/Graph Description Edge Profile Graph In the Edge Profile graph displayed when the Relative threshold is selected, the red line shows the percentage pixel intensity relative to the green threshold line. The threshold line will move up or down with the percent value. Absolute Threshold Absolute threshold finds an edge at a specific gray scale level.
PresencePLUS Software Tools 2/2010 Edge Strength Edge strength measures the rate of change of grayscale values and needs sharply-defined transitions. Edge strength is more tolerant of gradual changes in light levels across the tool than other transition types and it will filter out weak or gradual edges. Field Description Edge Enter an edge bandwidth value from 1 to 255. Polarity • Bright to Dark finds edges that start above the threshold value and cross below the threshold value.
2/2010 PresencePLUS Software Tools A bright-to-dark transition has a negative edge strength value, and a dark-to-bright transition has a positive edge strength value. When the Edge Strength level is adjusted, both the negative and positive green dotted lines will adjust together.

PresencePLUS Software Tools 2/2010 Note: Use Grayscale Blob when trying to distinguish white, black and shades of gray. Using Color Blob for grayscale analysis is not as effective as using Grayscale Blob. Color Blob Tool Color Map Visualization Hue, Saturation, and Intensity is a representation of color space that is closer to human perception of color dynamics. Hue and Saturation are represented in the circular color map, while Intensity is shown as a gradient bar.
2/2010 PresencePLUS Software Tools Blob Sort The Sort drop-down list allows the user to select a sort method to determine which Blob the sensor labels as "Blob #1." By default, Blobs are numbered according to scan order; that is, the sensor numbers Blobs as it encounters them while scanning the FOV from top-to-bottom and then left-to-right.
PresencePLUS Software Tools 2/2010 Blob Sort Order Once you select a Sort method, you need to define a Sort Order: • If Position is selected for the Sort method, then Blob order is based on the x,y coordinates of the centroids and the options are— • Left most • Top most • Right most • Bottom most • For any of the other options, Blob order is based on Increasing or Decreasing value of the parameter selected. For example, if Perimeter and Increasing is selected, the smallest perimeter Blob will be Blob #1.
2/2010 PresencePLUS Software Tools Color Blob Tool Advanced Tab Fields The following are fields on the Color Blob tool Advanced tab: • Advanced Options on page 182 • Range on page 183 • Color Blob Advanced Tab Results on page 183 Below is the Color Blob tool Advanced tab . Banner Engineering Corp.

2/2010 PresencePLUS Software Tools Option Description Compute Statistics Allows user to calculate and display advanced results. Fill Holes Allows user to ignore (by filling) small imperfections, or non-Blobs, within a larger Blob. Largest Hole to Fill allows users to specify the size of the imperfection so that valid non-Blobs are excluded. Enable Remote Teach Allows user to relearn the color identified by the color probe while the sensor is running.
PresencePLUS Software Tools 2/2010 Centroid The centroid (xc, yc) is the point at the center of mass of the blob. For simple blobs like solid circles, ellipses, or rectangles, this is just the center of the shape. For more complicated shapes it is helpful to imagine a piece of cardboard cut out in the shape of the blob. The centroid is the point where you could balance the cardboard on the tip of a pencil.
2/2010 PresencePLUS Software Tools This method of counting tends to slightly overestimate the "true" perimeter. For example, a circle with a radius of 100 pixels will have a computed perimeter of approximately 660 pixels, compared with the expected value of 628 pixels. If the camera is configured to convert pixel distances to other units, (e.g. inches), the perimeter will be given in those units.
PresencePLUS Software Tools 2/2010 where A is the area, (xc, yc) are the coordinates of the centroid and (xi, yi) are the coordinates of pixel i. These values represent the variance with respect to x, the variance with respect to y, and the covariance, respectively. The final results can be calculated as follows. The table below gives a more practical perspective on how to interpret these results.
2/2010 PresencePLUS Software Tools Min Radius and Min Radius Position The minimum radius of a blob is the distance from the centroid of the blob to the closest pixel on that blob's perimeter. The minimum radius position gives the pixel coordinates of that closest perimeter point. If the blob contains unfilled holes, the minimum radius position may be on the perimeter of a hole.

2/2010 PresencePLUS Software Tools 7.6.3 Math Tool The Math tool provides basic arithmetic, inequality expressions, and statistical information for PresencePLUS inspections. In general, the Math tool takes one or more pieces of information from Vision tools and makes mathematical espressions out of them. The results of the Math tool's analysis are displayed in the Result windows at the bottom of the screen. The inputs to the Math tool are called Operands.
PresencePLUS Software Tools 2/2010 Math Tool Modes One Operand Operation There is only a one operation that requires a single Operand--Absolute Value. This Operator requires the user to provide only one Operand. One Operand Functions abs Abs (Absolute value) returns Abs(X1). The absolute value of an operand is its unsigned magnitude. For example, Abs(-1.5) and Abs(1.5) both return 1.5 Two Operand Operations Two Operand Operations require two inputs (Operand 1 and Operand 2).
2/2010 PresencePLUS Software Tools • a specific attribute of interest for that tool. The following are classified as Two Operand Operations: • Add • Subtract • Multiply • Divide • Greater Than • Greater Than Equal To • Less Than • Less Than Equal To • Equal To • Diff • Mod • Div Arithmetic Operations Add Returns (X1 + X2) Subtract Returns (X1 - X2 ) Multiply Returns (X1 * X2) Divide Returns (X1 / X2) Relational Operations Greater Than If (X1 > X2) returns True, else False.
PresencePLUS Software Tools 2/2010 If the output of relational operation is used as an input for another Math Tool, True interpreted as 1 and False interpreted as 0. Two Operand Functions Diff (Difference) Returns Abs(X1 - X2). Returns the difference - absolute value of the difference between two operands. Mod (Modulus) Returns Mod(X1 / X2). The modulus, or remainder, operator divides operand1 by operand2 and returns the remainder. Div (Integer Division) Returns Div(X1 ÷ X2).
2/2010 PresencePLUS Software Tools Math tool outputs can be sent out via a Communications tool and/or used as an input to a Test tool (or another Math tool). Multiple Operand Functions Min (Minimum) Returns Min (X1, X2, ..., Xn). Returns the operand with the lowest value. Max (Maximum) Returns Max (X1, X2, ..., Xn). Returns the operand with the highest value. Count Returns Count (X1, X2, ..., Xn). Returns the count of operands. Sum Returns Sum (X1, X2, ..., Xn).
PresencePLUS Software Tools 2/2010 Examples Set Command Example Assuming that you have two Math tools, my_math_tool_1 and my_math_tool_2, each with their first operand configured as a constant. To set the constant of the second mathtool to 100.5, issue the following command: set mathtool my_math_tool_2 operand_1 100.5 or set mathtool 2 operand_1 100.
2/2010 PresencePLUS Software Tools Measure Tool Input Tab Measure Tool Operations Measure from a Point to a Point In this operation, the distance between two points is calculated. In addition, the X and Y components of that distance calculation are returned.
PresencePLUS Software Tools 2/2010 Measure from a Line to a Point In this operation, the software calculates the distance between a line and a point. This is the shortest distance from the line to the point, and is generated by creating a line perpendicular to the original line that intersects the point. In addition, it returns the distance calculations for the X and Y component.
2/2010 PresencePLUS Software Tools The curve, drawn in purple over the image of the bead, is an artifact generated by the bead tool. It shows the computed center spine of the bead detected by the Bead Tool within its ROI. The tool returns the distance calculations for the X and Y component.

2/2010 PresencePLUS Software Tools The tool returns the distance calculations for the X and Y component.
PresencePLUS Software Tools 2/2010 • When defining the angle between two lines, the Measure tool takes into account the order of the tool inputs. The sign of the angle from Line 1 to Line 2, for example, differs from the sign of the angle from Line 2 to Line 1. The tool detects the intersection point of two lines.
2/2010 PresencePLUS Software Tools The two shorter dashed lines represent the x- and y-components. The angle between MT_1 and the horizontal plane is the curved clockwise arrow. In the Results section of the Measure Tool window, this angle is listed as +53.11 degrees. How the Tool Measures Two Lines This mode finds the angle between two lines. Both inputs are existing Measure tools. The order in which these tools are input does matter. The intersection point can well be off the screen.
PresencePLUS Software Tools 2/2010 The Measure tool window to the left shows the settings and results of the inspection to the right. The inputs are both existing Measure tools (MT_1 and MT_2). The output, called MT_3, is the angle between the lines of each of the inputs. MT_3 is a curved counterclockwise arrow from the first input, MT_1, towards the arrowhead of the second input, MT_2. The Results section of the measure Tool window lists this angle a -90.00 degrees.
2/2010 PresencePLUS Software Tools The Measure tool window to the left shows the settings and results of the inspection to the right. In the Inspection image, the center point of BLOB_1 and the nearest point in the input line MT_1 define the dashed red line that runs from bottom left to top right. The actual measured distance between BLOB_1 and MT_1 is labeled MT_2. The solid red triangle shows where MT_1 and MT_2 intersect.
PresencePLUS Software Tools 2/2010 Relative For the Measurement type to be set to Relative, a Location-type tool must precede the Measure tool in the order of operation. When the user selects the Relative type, the window indicates to what Locate tool the measurement is relative. The coordinate system of the Measure tool changes based on the rotation information the Location-type tool provides.
2/2010 PresencePLUS Software Tools Preserve Sign When this checkmark is set, the X and Y distances are computed as distance offsets. These distance offsets are represented by signed numbers. Negative numbers mean distance offset is toward the origin (0,0), positive numbers mean distance offset is away from origin.

2/2010 Run Screen Record Tab 10.13.1 Record The Record tab is present on the Run screen when the vision sensor is running on live images (that is, the Start button has been pressed). Banner Engineering Corp.
Run Screen 2/2010 There are three steps to recording bitmap images using this feature: 1. Choose a Record Path. At the top of the tab, at the end of the line labeled Record Path, click the button. This will open up the Record to… window allowing you to browse for the folder where you want the images to be saved. 2. Choose a Record Mode. Right beneath the Record Path selection is the Record Mode drop down menu. This is where the user selects the conditions (if any) for saving images.
2/2010 Run Screen 10.13.2 Playback The Playback feature is available whenever the vision sensor is in Run mode but the Start button has not been pushed. To enter Playback mode on a currently running sensor, hit the Stop button. Clicking on the Playback tab will bring up the screen shown below left. This screen is almost exactly the same as the Record screen shown earlier: the only differences are the title of the tab and the fact that the Record button is inactive.
1. Load INP file. In Playback mode the vision sensor will be running off of stored images. These images will need to be evaluated in some way, using vision tools, etc. To begin the Playback process, load an INP file as if you are going to run the inspection on live images. When you get to the Run screen, however, hit Playback instead of Start. 2. Make a Playback List. At the bottom of the Playback screen is a box entitled Playback List.
Product Change Chapter 11 This section explains the Product Change (pin 3) input. The Product Change input is used in conjunction with one of the four I/O points programmed as Product Select lines. The inspection loaded will be executed following a valid trigger. • The Product Change input responds to the leading edge transition of a pulse greater than 1 millisecond. • The Product Select input is pulsed to correspond to a program location. For example, five pulses will load program #5. 11.
11.2 Product Select Input Specifications State Current Sinking (NPN) Current Sourcing (PNP) ON < 2V at 1 mA max. > 8V at -7.5 mA max. OFF > 10V at 4 mA max. < 2V at -7.5 mA max.
P4 Product Change and Product Select12 Chapter Timing 12.1 One Pulse Set Overview The Product Change line signals the Sensor to stop what it is doing and begin counting pulses on the Product Select line. The number of pulses indicates to the Sensor the inspection address at which to begin executing the inspection. The only pulses counted are those that occur when the Product Change input is active.
P4 Product Change and Product Select Timing 2/2010 12.1.1 Product Select in One-Pulse Configuration To use the product select option in the one-pulse configuration, follow these steps. 1. 2. 3. 4. Select Hardware Input in the Select tab of the Run Screen. Configure an I/O for Product Change in the System-Input/Output screen. Set the Product Select Type to "One Pulse Set". Assert the Product Change signal and then assert the number of pulse representing the inspection number to go to.
2/2010 P4 Product Change and Product Select Timing • First set of pulses are for the 100's digit. • Second set of pulses are for the 10's digit. • Third set of pulses are for the 1's digit. The use will need to assert the Product Change signal for each set of pulses. To do this, the Product Change signal must be asserted and held while the pulses representing the digit are being sent, and released after the last pulse is given. Valid range of pulses for all digits is 0 - 9. Banner Engineering Corp.
