Requires: NI Scan Engine
Select a target with the NI Scan Engine installed to display this view in the Auto View. You also can right-click the target and select Probe to display this view in a separate window. Use this view to monitor and manage the scan engine running on the target.
This view includes the following components:
- Forcing—Contains information and options related to I/O variable forcing.
|Note Forcing does not persist after a reboot of the target.|
- Forcing Enabled—Indicates whether forcing is enabled on the target. Forcing must be enabled on the target for individual I/O variable or I/O alias forces to take effect. This setting serves as a master switch for all I/O variable and I/O alias forcing on the target.
- Enable Forcing—Enables forcing on the target, switching the state of the Forcing Enabled setting to TRUE. This option is available only when I/O variable forcing is disabled.
- Disable Forcing—Disables forcing on the target, switching the state of the Forcing Enabled setting to FALSE. This option is available only when I/O variable forcing is enabled.
|Note Unless you clear forcing, the previous forced values of all forced I/O variables and I/O aliases return when you re-enable forcing on the target.|
- Clear Forcing—Unforces all currently forced I/O variables and I/O aliases on the target and returns control of the I/O values to the NI Scan Engine.
|Note This button does not affect the master Forcing Enabled setting on the target.|
- Faults—Contains information and options related to scan engine faults.
- Fault Present—Indicates the presence of faults on the target. The LED appears black when no fault is present, orange when only minor faults are present, and red when major or unrecoverable faults are present.
- Clear All Faults—Clears all faults on the target. If the target is in Fault mode, clearing all faults returns the target to the previous mode in effect before entering Fault Mode.
- Clear Selected Fault—Clears the fault currently selected in the Fault List. If no fault is currently selected, no action occurs.
- Fault List—Lists the faults active on the target.
- Error Code—The error code associated with the fault.
- Highest Level—The highest level of the fault since last cleared.
- First Occurrence—The time of the first occurrence of the fault since last cleared.
- Num of Occurrences—The number of occurrences of the fault since last cleared.
- Description—The fault description.
- Scan Engine Mode—Contains information and options related to the mode of the NI Scan Engine on the target.
|Note This section is available only with expansion I/O hardware. This section is not available if only local I/O drivers are installed on the target. Refer to the I/O hardware documentation for information about hardware-specific mode behavior.|
- Configuration—Indicates whether the scan engine is in Configuration mode.
- Active—Indicates whether the scan engine is in Active mode.
- Fault—Indicates whether the scan engine is in Fault mode.
- I/O Drivers—Lists the I/O drivers installed on the target that interface with the NI Scan Engine.
- Change to Configuration—Switches the scan engine to Configuration mode. If the target was previously in Fault mode, switching to Configuration mode automatically changes the level of all active major faults to minor.
- Change to Active—Switches the scan engine to Active mode. You cannot switch directly to Active mode from Fault mode. You must clear all major faults to leave Fault mode before you can switch to Active mode.
- Refresh Local Modules—Discovers new I/O modules on the target. If a local I/O module is detected in a slot that was not previously deployed from a LabVIEW project, this operation creates new I/O variables for the I/O module. These automatically created I/O variables use the default I/O variable settings. This operation does not add the new I/O variables to a LabVIEW project, and the new I/O variables do not persist when the target restarts.
If you physically change an I/O module deployed from a LabVIEW project, this operation cannot overwrite the deployed configuration until you undeploy the I/O module in the LabVIEW project. However, if you physically change an I/O module that was automatically detected by this operation or the corresponding Refresh Local Modules VI, this operation adds and deletes automatically created I/O variables to match the new physical configuration.
