Using 4 wire PT1000 with NI 9219

[Aditi.hiray]

I am using PT1000 on my NI9219 hardware to collect temperature data using DAQmx. 

I have created a one seperate task for taking inputs of T1 and T2. When I run the task, It is showing temperature values. But when I create a simple program for this, values are not at all dispying. What will be the possible reasons?

So the reason will be within that "simple program" which you created, but failed to attach!

Sorry, I forgot to attached..

Here I have attached both my programs,

1.  for t1 temp input (test)

2. with t1, t2 and flow meter (Analog input)

Run the program with highlight execution and see step by step  where the error is happening.

Thanks for suggesting me highlight execution method. 

I am getting following errors:

 200077 (Read mx) although I have specified my channels.

200072 (Create a channel) If I select my temperature task in 'task in' 

Since I am new in Labview programming, correct me if I am doing anything wrong. 

I appreciate your help 🙂

Did you read the error explanations?

-200077: unsupported value of the property

-200072: duplicate channels in task not supported

Do you correctly setup the DAQmx task?

Which DAQmxRead gives the error?

Why do you select a task when you explicitely wire channels to the CreateChannel function?
