If the task’s Trigger Event type is set to "Image In Event," the time starts when the camera trigger is
complete, not at the beginning of task execution. For all other Trigger Event settings, the time starts
when task execution begins. The timing accuracy depends on the tools in the task, but it is generally
accurate to within a few milliseconds.
For example, if Task Timeout is enabled, and the Timeout value is set for 10,000 milliseconds, a task
will run until it completes or 10,000 milliseconds has elapsed, whichever comes first. If the Task
Timeout occurs first, and Abort On Error is True, the Abort Task runs, if one is defined. If Abort On
Error is False, then the task keeps running and any remaining tools immediately fail. See “VPM Task
Configuration” on page 3-34 for more details.
• Data Transfer Tool - When if this property is enabled, the Timeout value indicates the maximum
length of time the tool will wait for a control panel response before it stops trying to send data to it.
For example, if the timeout is enabled, and the Timeout value is set for 10,000 milliseconds, if the
control panel does not respond to the tool’s command within 10,000 milliseconds, the transfer is ter-
minated.
Settings Files
This section lets you select what Datalogic Impact device settings are saved and printed. Both is selected by
default. To copy settings files from one device to another, see “To copy settings files from one device to
another” on page 2-8.
IMPORTANT NOTE: Settings files contain information about which vision programs should be loaded
when the device starts. Since vision program files are not copied to the device when you backup and restore
the settings file, some vision programs may not get loaded when the device starts. It is the system program-
mers responsibility to insure that the proper vision program files are copied to the device.
• Camera Calibration: When you click Backup, the settings displayed on the Camera System Object -
Setup Tab - Calibration panel are saved to the client. Restore sends the camera calibrations from the
client’s file to the device. Calibration settings are also saved whenever the calibration is changed.
• Vision Device Settings: When you click Backup, the settings displayed on the General System Object
are saved to the client. Restore sends the device settings from the client’s file to the device.
• OPC Data Access: When you click Backup, the OPC data settings displayed on the OPC Data Access
System Object are saved to the client. Restore sends the device settings from the client’s file to the
device.
IMPORTANT NOTE: Restore will overwrite any existing settings on the device with those currently on
the client computer. If more than one client computer is connected to the device, the most recently restored
settings are kept on the device.
• Restore: The Restore button sends device settings currently saved on the client computer to the
device. Vision program files are not copied to the device. See “Folder List” on page 2-37 for image
file copying details.
IMPORTANT NOTE: The client computer will backup the settings for only one device at a time. Only the
currently connected device’s settings are backed up. Any previously saved settings are overwritten.
• Backup: The Backup button saves the selected settings from the device to the client computer. Vision
program files are not copied from the device. See “File List” on page 2-38 for image and vision pro-
gram file copying details.
