IviDCPwr Configure OVP (G Dataflow)

Last Modified: September 7, 2018

Configures the power supply's over-voltage protection. You specify the over-voltage limit and the behavior of the power supply when the output voltage is greater than or equal to that value. When the enabled parameter is FALSE, the limit parameter does not affect the instrument's behavior, and the driver ignores the limit parameter.

instrument handle

The instrument handle that you obtain from the IviDCPwr Initialize or IviDCPwr Initialize With Options node. The handle identifies a particular instrument session. Default Value: 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

datatype_icon

channel name ("CHANNEL1")

Specifies the virtual channel name that you assign to the instrument in the Configuration Utility. Users who want to achieve interchangeability should use a virtual channel name. The virtual channel name should be sufficiently specific to the test system such that it is unlikely to conflict with a physical channel name. Virtual channel names are aliases for instrument-specific channel strings. The instrument-specific channel strings can differ from one instrument to another. Virtual channel names allow you to use and swap instruments without having to change the channel names in your source code. You assign a virtual channel name to an instrument-specific channel through the Configuration Utility. This control accepts virtual channel names you have assigned to the specific instrument you are using. It also accepts the instrument-specific channel names.

Default: "CHANNEL1"

datatype_icon

limit

Specifies the over-voltage protection limit you want to use. The driver uses this value to set the IviDCPwr>>Basic Operation>>OVP Limit property. Units: volts

Default: 0.0 V

datatype_icon

enabled

Specifies whether you want to enable or disable the OVP limit. The driver uses this value to set the IviDCPwr>>Basic Operation>>OVP Enabled property.

TRUE Enable OVP limit
FALSE Disable OVP limit

Default: True

datatype_icon

instrument handle out

The instrument handle that you obtain from the IviDCPwr Initialize or IviDCPwr Initialize With Options node. The handle identifies a particular instrument session. Default Value: None

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
