The Fieldpoint IO Point In on the FP Read may not be specified correctly. If you are only specifying a few IO Points, check each one by selecting browse, when you click the down arrow next to the control or constant. If you can browse and select each point, the program should work without this error. You can also check in Measurement and Automation Explorer (MAX) to see if this tag exists. The controller is specified in MAX under Data Neighborhood in the iak file listed. The following KnowledgeBase goes into this.
If you are trying to use different iak files, the iak file that is used by default in LabVIEW is the one that was open in MAX when LabVIEW opens. If you want to specify another iak file after LabVIEW is opened, open the other iak file in MAX. You can then select browse again on the IO Point control and go to the View Configurations tab to select the iak file you want to use.
