Points marked with red plus signs (+): 6
outside the circle:
Contrast < 0, ball is darker than the background 6
within the circle:
Contrast > 0, ball is lighter than the background 6
Points marked with yellow minus signs (-): 6
The difference between the plus and minus signs represents
the radial tolerance. 6
2. Ball mode 6
See Section 6.6.4.14
on page 289 for a definition of the measuring methods. 6
The method works with high precision and is thus suitable for precisely determining the position
of all defined balls. As a higher precision search, ball mode will follow grid mode. 6
This measurement method can be identified 6
– by the synthetic model being shown in pixel resolution at the lefthand edge of the video image,
– by there being a window around every ball (separate window) or
Procedure: 6
All of the balls defined in the package form file are surveyed. Geometric criteria are used here in
the selection of the window mode: 6
– If the balls are relatively far apart the separate window mode will be selected. The default win-
dow mode is the separate window mode.
Window: 6
dark blue: Over a single ball in each case (separate window) 6
Over a row or over all balls (combined window) 6
Cross: 6
white: Measured ball candidates which are defined in the package form file. 6
Crosshairs: 6
white: Results of position recognition -> X and Y-angles 6
Star: 6
white: Position of the component 6

6.6.4.5 Store image Option
NOTE 6
You cannot click on this option until a package form number has been loaded.
Fig. 6.6 - 22 Test component menu, Store image option
This menu is used to store the generated video image as a file on the hard disk of the machine
controller. The file name and path are preset to: 6
D:\TMP\MVSBILD.MVS 6
For further analysis at Siemens AG, copy the file from the hard disk of the MVS controller onto a
diskette and send it to the PL EA Service Department. 6

Fig. 6.6 - 23 Test component menu, Evaluat. time option
This option is used to display the evaluation time for a selected component. Once you have acti-
vated the function, the following actions are started: 6
– The measuring procedure is activated.
– The video image appears on the screen
– The evaluation time is overlaid.
