Configures the current limit for the specified channel(s). The channel must be enabled for the specified current limit to take effect.

Refer to the niDCPower Configure Output Enabled VI for more information about enabling the output channel. The current limit is the current that the output should not exceed when generating the desired voltage level. The current limit setting is only applicable if the channel is set to the DC Voltage output function using the niDCPower Configure Output Function VI.

channel name specifies to which output channel(s) to apply this configuration value. 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.

current limit specifies the current limit on the specified channel(s).

The limit is specified as a positive value, but symmetric positive and negative limits are enforced simultaneously.

The valid values for this parameter are defined by the current limit range that is configured using the niDCPower Configure Current Limit Range VI.

behavior specifies how the output current should behave when the current limit is reached.

Regulate The power supply controls the output current so that it does not exceed the current limit. The power supply continues to generate power, even if the current limit has been reached.

error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.

status is TRUE (X) if an error occurred before this VI ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI ran. The default is FALSE.

code is the error or warning code. The default is 0. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.

source describes the origin of the error or warning and is, in most cases, the name of the VI that produced the error or warning. The default is an empty string.
