Click a button to turn the indicated output on and off. The indicator is green when the output is on.
Strobes
Use this function to test your strobe outputs. When you click a strobe button, the corresponding output will
pulse for 30 microseconds.
Options
I/O Polling Rate
Enter a number from 50 to 10,000 milliseconds. VPM polls the Datalogic Impact device at this rate and
updates all the indicators on the Diagnostics tab.
NOTE: Enable System Log Trace only when you need to trace all system events. For instance, if you are
having trouble tracking down an intermittent problem with a vision program. The system log can quickly
become filled with entries and system performance can be affected, depending on the program’s complexity.
Enable System Log Trace
When this is checked, all system events that occur on the device are entered in the system log. This includes
events, task and tool run completion, and many other occurrences that would not ordinarily get logged.
Inputs
This section shows the current state of each device input. (VPM polls the device at the I/O Polling Rate
shown.) The indicator is green when the input is On. If the input change rate is too fast, the indicator may not
switch quickly enough to indicate the true current state.
To test an input, connect a "loopback" between an output and the input. The input’s state will change when
the output changes.
Events
This section shows the hardware signal frequency on the device’s trigger, shift, or event inputs (in Hz).
These values are inactive if the device is not online and receiving hardware trigger signals. The appropriate
Trigger Event property must also be set.
Trigger Rate: The signal on the Trigger Input. A task that has the Trigger Event property set to one of the
types of Image Trigger Event must be loaded.
Shift Rate: The signal on the Shift Input. A task must be loaded that has the Trigger Event property set to
one of the types of Shift Event must be loaded.
Event Rate: The signal on the Event Input. A task must be loaded that has the Trigger Event property set to
one of the types of Input Event must be loaded.
Reboot Device
Click this button to restart the device. All tasks stop executing and all vision programs are unloaded. (This
has the same effect as pressing the Reset button on the device.)
When the device restart has completed, any vision programs set to load on startup are loaded and tasks in
those vision programs are queued to execute when they are triggered. See “File Manager Setup Tab” on
page 2-37 for setting vision programs to load on startup.
IMPORTANT NOTE: The device must completely reboot (the Stat indicator light is off) before you can
connect to it.
Advanced
This button presents a menu of advanced functions.
