Camera Preferences
• Display Refresh Rate: The rate at which the Summary Table and Display tab values are refreshed
while VPM is in Start/Stop Continuous Trigger mode or online. If the system is online, this setting
affects only the refresh rate, not the trigger rate.
• Display Refresh Timeout: Occasionally communication timeouts can cause VPM to stop refreshing
the Summary Table and Display tab values. The timeout value can be too short for the amount of
information being gathered for display and/or the Impact device is being triggered at a rate that does
not allow it to return information to VPM. If a timeout occurs after three consecutive attempts, a
warning is displayed indicating that you should increase this setting. You should adjust this timeout
value only after you have received this warning.
The timeout can be adjusted from one to thirty seconds; each mark on the scale represents approxi-
mately three seconds.
• Auto Image History:
NOTE: In high speed applications, some images may not be saved if saving them delays task execution.
Determining factors can include the VPM update rate, the device’s trigger rate, inspection speed, and
task execution time.
In PC Memory: Images are stored in PC memory and can be accessed using the Image History
button (see “Image History” on page 3-12).
Type
: Select the type of image you want to save. Depending on the inspection speed and task pro-
cessing time, some images may not be saved if saving them delays task execution.
Maximum Images
: Enter the number of images to save (from two to twenty images depending on
the image size and the amount of available PC memory).
Save to File: Images of the selected Type from the currently selected tool or task are saved when
Start/Stop Continuous Trigger is selected or the Impact device is online and getting triggers. If the
tool does not have an image display, images from the Summary tab are saved.
Enable
: If checked, and either the Design or Display tab is selected, VPM saves the selected type of
image to the indicated path. Images are saved as a png file type. NOTE: You must also link the
task’s Pass/Fail status on the Task display panel (see “Options panel” on page 3-22).
Type
: Select the type of image you want to save. Depending on the inspection speed and task pro-
cessing time, some images may not be saved if saving them delays task execution.
Path
: Use the default path, enter a valid path to a folder where you want to save the images, or click
Browse to find a folder. The IP address of the currently selected Impact device is appended to the
path name and a folder is created if it does not exist. The IP address directory name is NOT shown
in the path field. For example, if you enter the path c:\image_directory, the images are saved in the
folder c:\image_directory\192.168.108.65
Name
: This name, along with the image number count, is used as the saved image’s file name.
IMPORTANT: File names are case sensitive.
Rollover at
: Previously saved images are overwritten after this number of images has been saved.
