Performing a
Single Sweep
From the networks panel (tree), right click menu:
Step Action
1 Select Sweep.
2 In the Sweep Mode area, select the Single Sweep radio button.
3 Enter the target time (in 10’s of milliseconds) for each scan in the Time box.
Note: If the actual scan takes less time than the target scan time, the controller
waits for the target scan time to elapse before performing the next scan. If the
actual scan takes more time than the target scan time, the controller finishes the
scan, then continues on with the next scan. This lets you force the scan time to
a higher rate when debugging logic that the controller may solve too quickly to
otherwise catch.
4 Enter the number of scans (1-15) to be performed during the sweep the Scans
box.
5 Click OK.
6 When you are ready to perform the sweep, select Sweep from the networks
panel (tree) right click menu.
7 Select one of the following radio buttons:
Invoke: Select to start the sweep.
Trigger: Select to set a trigger for the sweep.
Turn Off: Select to shut off the sweep.
8 Click OK. The controller performs the scans (unless you selected Turn Off), then
stops solving logic with all outputs frozen in their last state.
You can then browse register contents and perform other diagnostics using this
"snapshot" of the solving process.
