PXI-4110 current limit

Question

I am programming a PXI-4110 with LabWindows. I am trying out the current limiting. I have an output set to 5V with a 1K load resistor; this makes the current 5mA. I set the current limit to 2mA to see it work. When I read the voltage and current it is still 5V and 5mA. Here is my code:
g_voltageLevel_ch0 = 5.0;
g_currenLimit_ch0= 2.0e-3;
 status = niDCPower_ConfigureOutputFunction(vi_4110_0, channel0Name, NIDCPOWER_VAL_DC_VOLTAGE);
 niDCPower_error_message(vi_4110_0, status, errorMessage);
 status = niDCPower_ConfigureSense(vi_4110_0, channel0Name, NIDCPOWER_VAL_LOCAL);
 niDCPower_error_message(vi_4110_0, status, errorMessage);
 status = niDCPower_ConfigureVoltageLevel(vi_4110_0, channel0Name, g_voltageLevel_ch0);
 niDCPower_error_message(vi_4110_0, status, errorMessage);
 status = niDCPower_ConfigureCurrentLimit(vi_4110_0, channel0Name, NIDCPOWER_VAL_CURRENT_REGULATE, g_currenLimit_ch0);
 niDCPower_error_message(vi_4110_0, status, errorMessage);
Solved!

Answer 1

I'm getting an error now. I have a 1K resistor on each of the outputs so I will see some current.
Look for these lines
to see comments I am sending you about the code.
When I start my program I call a function PXI4110_HardwareInit() to get things set up. This part seems to look OK.
/************************************** PXI-4110 ****************************************/
// PXI-4110 hardware definitions for initialization
static ViSession vi_4110_0 = VI_NULL, vi_4110_1 = VI_NULL, vi_4110_2 = VI_NULL;
/* The channel names are length 2 because the maximum size of the strings
from the each textbox on the UI is 1. */
static ViChar channel0Name[2] = "0";  // 0V to 6V channel
static ViChar channel1Name[2] = "1";  // 0V to 20V channel
static ViChar channel2Name[2] = "2";  // 0V to -20V channel
// inputs
ViReal64 g_voltageLevel_ch0 = 5.0;
ViReal64 g_voltageLevel_ch1 = +13.0;
ViReal64 g_voltageLevel_ch2 = -13.0;
ViReal64 g_currenLimit_ch0 = 500.0e-3;
ViReal64 g_currenLimit_ch1 = 500.0e-3;
ViReal64 g_currenLimit_ch2 = 500.0e-3;
void PXI4110_HardwareInit(void)
 ViStatus status;
 ViChar errorMessage[256];
    ViChar resourceDCSupplyName[256] = "PXI-4110";
 // set channel 0 to +5.0V
 status = niDCPower_InitializeWithChannels(resourceDCSupplyName,channel0Name,VI_TRUE,VI_NULL,&vi_4110_0);
 if(status < 0)
  niDCPower_error_message(vi_4110_0, status, errorMessage);
 status = niDCPower_ConfigureOutputFunction(vi_4110_0, channel0Name, NIDCPOWER_VAL_DC_VOLTAGE);
 niDCPower_error_message(vi_4110_0, status, errorMessage);
 status = niDCPower_ConfigureSense(vi_4110_0, channel0Name, NIDCPOWER_VAL_LOCAL);
 niDCPower_error_message(vi_4110_0, status, errorMessage);
 status = niDCPower_ConfigureCurrentLimitRange(vi_4110_0,channel0Name,  1.0);
 niDCPower_error_message(vi_4110_0, status, errorMessage);
 Set_PXI_4110_Outputs();
 status = niDCPower_ConfigureOutputEnabled(vi_4110_0, channel0Name, VI_FALSE);
 status = niDCPower_Initiate(vi_4110_0);
 niDCPower_error_message(vi_4110_0, status, errorMessage);
static void Set_PXI_4110_Outputs(void)
 ViStatus status;
 ViChar errorMessage[256];
 // channel 0
 status = niDCPower_ConfigureVoltageLevel(vi_4110_0, channel0Name, g_voltageLevel_ch0);
 niDCPower_error_message(vi_4110_0, status, errorMessage);
 status = niDCPower_ConfigureCurrentLimit(vi_4110_0, channel0Name, NIDCPOWER_VAL_CURRENT_REGULATE, g_currenLimit_ch0);
 niDCPower_error_message(vi_4110_0, status, errorMessage);
Then I send a message on ethernet to enable the outputs: When I enable the outputs this function reads the voltage and current outputs and sends this information to a application on my host computer. This information corresponds to what I set it to and what I see with a volt meter.  
void PXI_4110_enable_outputs(void)
 ViStatus status;
    ViReal64 measuredVoltage, measuredCurrent;
    ViBoolean inCompliance;
 ViChar errorMessage[256];
 // set the outputs
// Set_PXI_4110_Outputs();
 status = niDCPower_ConfigureOutputEnabled(vi_4110_0, channel0Name, VI_TRUE);
      /* Wait for the outputs to settle. */
     Delay(50e-3);
  // check channel 0
  status = niDCPower_MeasureMultiple(vi_4110_0, channel0Name, &measuredVoltage, &measuredCurrent);
  niDCPower_error_message(vi_4110_0, status, errorMessage);
  niDCPower_QueryInCompliance(vi_4110_0, channel0Name, &inCompliance);
  niDCPower_error_message(vi_4110_0, status, errorMessage);
Now I send a message to change the current limit. This is where I have trouble. I try and limit the current on Channel 0 to 2mA. Since the output voltage is 5Volt and the resistor is 1K the current will exceed the current limit which is what I am trying to test. I get an error in this function>
   g_currenLimit_ch0 = CommandData->data; 
   status = niDCPower_ConfigureCurrentLimit(vi_4110_0, channel0Name, NIDCPOWER_VAL_CURRENT_REGULATE, g_currenLimit_ch0);
   niDCPower_error_message(vi_4110_0, status, errorMessage);
I see g_currentLimit_ch0 = 2e-3 whic is whatI sent. but my status is a negative number. The message is "Invalid value for parameter or property"
vi_4110_0 is the handle I got earlier.
channel0Name ="0"
and g_currentLimit_ch0 = 2e-3
I do not understand why I am seeing and error here?????????????????????
thanks in advance for your help,
Don
