Returns the voltage protection state of the AC power source. Voltage protection trips when the output voltage is above the IviACPwr Over Voltage Protection Limit [VP] property or below the IviACPwr Under Voltage Protection Limit [VP] properties and the corresponding voltage protection property, IviACPwr Over Voltage Protection Enabled [VP] or IviACPwr Under Voltage Protection Enabled [VP], is set to True. When voltage protection trips, the power source enters the voltage protection state and disables the output. The user must call the IviACPwr Reset Voltage Protection [VP] VI to reset the voltage protection state of the AC power source. Once voltage protection is reset, the user must then set the IviACPwr Output Enabled property to True for the AC power source to resume generating output voltage.
The instrument handle that you obtain from IviACPwr Initialize or IviACPwr Initialize With Options. The handle identifies a particular instrument session.
Default: None
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Specifies the name of the output phase to query. Pass the virtual output phase name that you assign to the instrument in the IVI Configuration utility. Users who want to achieve interchangeability should use a virtual output phase name. The virtual output phase name should be sufficiently specific to the test system such that it is unlikely to conflict with a physical output phase name. Virtual output phase names are aliases for instrument-specific output phase strings, which can differ from one instrument to another. With virtual output phase names, you can use and swap instruments without having to change the output phase names in your source code. Assign a virtual output phase name to an instrument-specific output phase through the IVI Configuration utility. This control accepts virtual output phase names you have assigned to the specific instrument you are using and also accepts the instrument-specific output phase names. Default Value: "" Note: You can specify the output phase name as a string variable or as a literal enclosed in double quotes.
