I am trying to acquire signal from 3 RTDs using a NI 9217. I can get them to work fine using DAQ Express. However, I am trying to avoid using Express VIs, because this is a small part of a much more complex system. Whenever I try to run the VI, I get Error 200077which says that I selected an external excitation source instead of choosing an internal source. I changed the setting to be internal. However, I still get the same error regardless. How do I correct this?
