Hello I have had a running program until Windows 11 update. The program works on multiple devices that do not have Windows 11 so I believe it has something to do with that.

I will post some of the error messages and code below. Please let me know of any other info needed in order to tackle this.

LabJack.LabJackUD.LJUD.LJUDERROR.AD_PIN_CONFIGURATION_ERROR

Message = "Exception of type 'LabJack.LabJackUD.LabJackUDException' was thrown."

at LabJack.LabJackUD.LJUD.GetFirstResult(Int32 handle, IO& IOType, CHANNEL& channel, Double& val, Int32& px1, Double& userData)\r\n

LJUD.IO ioType = 0;
LJUD.CHANNEL channel = 0;
double dblValue = 0;
double Value0 = 9999, Value1 = 9999, Value2 = 9999;
double ValueDIBit = 9999, ValueDIPort = 9999, ValueCounter = 9999;
int dummyInt = 0;
double dummyDouble = 0;

try

{

for (int j = 0; j < 8; j++)
{
LJUD.AddRequest(myU3.ljhandle, LJUD.IO.GET_DIGITAL_BIT, j, 0, 0, 0);
}

LJUD.GoOne(myU3.ljhandle);

LJUD.GetFirstResult(myU3.ljhandle, ref ioType, ref channel, ref dblValue, ref dummyInt, ref dummyDouble);
}
catch (LabJackUDException e)
{

}

The error indicates a problem

The error indicates a problem with your pin configuration. You should ensure your analog enable config is set correctly. I would also recommend doing a pin configuration reset at the start of your script and configuring everything how you need afterwards. Please see the following relevant pseudocode:

If you are using the U3-HV, you cannot set DIO0-3 to digital inputs and there would be an issue with your loop of GET_DIGITAL_BIT commands.

Thank you, this was helpful.

Thank you, this was helpful. I changed the loop to the following and the problem was fixed.

for (int j = 4; j < 8; j++)
{
LJUD.AddRequest(myU3.ljhandle, LJUD.IO.GET_DIGITAL_BIT, j, 0, 0, 0);
}
