Iam using NI datalogger,for reading analog and digital inputs.In this datalogger there are many sub VIs.when i run the data logger iam getting the errors like, the sub vi PDSF_logistics.vi(process data standard format )is not executable.The error what it is showing is
Invoke node:Invalid method
The method selected in the invoke node is invalid or no method has been selected. Right-click the invoke node and select a method.
Invoke node:Invalid refnum class
The refnum class that is being passed into this node is not fully defined. This is because the refnum is defined using external files, and one or more of these files are missing.
Iam attaching the VI please have a look in to it.
