• Calibration Editor - When you save images in VPM, the lens calibration information is stored with
them. You can edit the calibration values, or copy that information to other image files.
• Memory Meter - This utility displays the current memory usage for a device. The amount of avail-
able memory shown is not updated while the device is online.
• TCP Tester - This utility emulates a device to test Ethernet between the client and Datalogic Impact
devices.
• Modbus TCP/IP Client - Send commands to and read information directly from the Datalogic
Impact device Modbus TCP/IP Server using Modbus TCP/IP protocol. (Datalogic Impact devices do
not support serial Modbus protocol.) See “Modbus TCP/IP Client Tester” on page 6-27 for more
details.
Save Image Buffers
NOTE: This button is disabled for T4x-Series, M-Series, and A30 cameras.
This advanced troubleshooting function is intended to be used to find an image that causes the device to stop
responding. If a Datalogic Impact device crashes, and you suspect it may be caused by processing a specific
image, follow the steps below. This button is disabled if VPM is connected to an Emulator.
To Save the Image Buffers
1. Do NOT cycle power! This will alter the pixels in the image buffers.
2. If the Impact device is set to go online on start up, disconnect all trigger sources before proceeding.
Triggering will overwrite the image buffers.
3. Push the reset button on the device. It is located near the power connector on the C-Series and T3x-
Series devices, and on the back panel of the A20 camera.
4. Wait for the device to restart. The restart is complete when the status light turns off.
5. Start VPM and connect to the Datalogic Impact device.
6. Go to the Settings tab, General icon, Diagnostics panel.
7. Press the “Save Image Buffers” button. The saving process will take about 20 seconds as it is saving
~20 MB of images
8. Go to the File Camera icon, Setup tab. You will see available images named “DiagnosticBuffer000”,
“DiagnosticBuffer001”, etc. The number of buffers will vary with the camera type and partial scan set-
tings.
9. Select the diagnostic buffer images and activate them.
10. Load the vision program files that were running when the device crashed.
11. Go to the ImageIn task and cycle through the images using the “Trigger Once” button.
12. You are trying to find one of the images that caused the device to crash. You can tell that the device has
crashed when the Trigger Once button fails to come back within a few seconds, the Impact device's sta-
tus light stays on and, eventually, VPM reports a “Connection Problem.”
13. The image that crashed the device is the next one after the one currently displayed in the VPM image
window. For example, if DiagnosticBuffer010.png is displayed in the image window, then
DiagnosticBuffer011.png is the one you want.
14. Push the reset button on the device and wait for the device to restart.
15. Go to the Settings tab, File Manager icon, select the suspect image file in the Images directory, and
copy it to your PC.
16. Send the image file and your vision program files to Datalogic for diagnosis.
