InTouch Standalone  App

  • NAD is optional with InTouch Standalone.  It is enabled by checking the checkbox for "Enable Network Application Development".
  • It is configured from the InTouch Application Manager by selecting Tools | Node Properties.
  • The Local working directory is C:\Users\Public\Wonderware\NAD.
  • There is a Polling period in seconds.  This is how often it checks for changes.
