ViStatus niDCPower_ConfigureVoltageLimit(ViSession vi, ViConstString channelName, ViReal64 limit);


Configures the voltage limit for the specified channel(s). The channel must be enabled for the specified voltage limit to take effect. Refer to the niDCPower_ConfigureOutputEnabled function for more information about enabling the output channel.

The voltage limit is the voltage that the output should not exceed when generating the desired current level. The voltage limit setting is applicable only if the output function of the channel is set to NIDCPOWER_VAL_DC_CURRENT. Use niDCPower_ConfigureOutputFunction to set the output function.

Name Type Description
vi ViSession Identifies a particular instrument session. vi is obtained from the niDCPower_InitializeWithChannels function.
channelName ViConstString Specifies the output channel(s) to which this configuration value applies. Specify multiple channels by using a channel list or a channel range. A channel list is a comma (,) separated sequence of channel names (for example, 0,2 specifies channels 0 and 2). A channel range is a lower bound channel followed by a hyphen (-) or colon (:) followed by an upper bound channel (for example, 0-2 specifies channels 0, 1, and 2). In the Running state, multiple output channel configurations are performed sequentially based on the order specified in this parameter.
limit ViReal64 Specifies the voltage limit, in volts, on the specified output channel(s). The limit is specified as a positive value, but symmetric positive and negative limits are enforced simultaneously.

Valid Values:
The valid values for this parameter are defined by the voltage limit range that is configured using the niDCPower_ConfigureVoltageLimitRange function.

Return Value

Name Type Description
StatusViStatusReports the status of this operation. To obtain a text description of the status code, call the niDCPower_error_message function. To obtain additional information concerning the error condition, call the niDCPower_GetError function.
