IviACPwr Configure Current Protection [CP] (G Dataflow)

Last Modified: October 24, 2017

Configures current protection. When the Current Protection Enabled input is True, the power source enters the current protection state (tripped) and disables the output when the output current exceeds the current threshold for the current delay time. When the Current Protection Enabled input is False, the threshold and delay do not affect the behavior of the instrument and current protection is disabled.

Threshold

Specifies the current threshold that triggers over current protection. The driver uses this value to set IviACPower Current Protection Threshold [CP] property. Default Value: None

datatype_icon

instrument handle

The instrument handle that you obtain from IviACPwr Initialize or IviACPwr Initialize With Options. The handle identifies a particular instrument session.

Default: None

datatype_icon

error in

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.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

Phase Name ("")

Specifies the name of the output phase to configure. 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.

Current Protection Enabled (True)

Enables or disables current protection. The driver uses this value to set IviACPwr Current Protection Enabled [CP] property. Valid Values: TRUE - Enables the current protection. FALSE - Disables the current protection. Default Value: True

datatype_icon

Delay

Specifies the time the output current must exceed the over current protection threshold until over current protection is triggered. The driver uses this value to set IviACPwr Current Protection Delay [CP] property. Unit: second Default Value: None

datatype_icon

instrument handle out

The instrument handle that you obtain from IviACPwr Initialize or IviACPwr Initialize With Options.

error out

Error information.

The node produces this output according to standard error behavior.
