Configure disconnected startup

Use PI ICU to configure disconnected startup for the interface.

1. In PI ICU, select the interface instance and select Disconnected Startup from the UniInt tab.

2. Select the Enable disconnected startup (with point caching) check box.

3. Required: Configure the cachemode parameter for disconnected startup.

4. Configure optional parameters:

   • pisdk

     If you use PI SDK to retrieve extended point attribute information for points from Data Archive, disable PI SDK by defining /pisdk=0 in the .bat file, or remove any disconnected startup parameters.

     Disconnected startup requires PI API. Some UniInt based interfaces require PI SDK to retrieve point information if PI API is earlier than version 1.6 or Data Archive is earlier than version 3.4.370.x. In this case, setting the /pisdk=0 startup parameter may not disable PI SDK, prohibiting the use of disconnected startup. Running disconnected startup with PI SDK configured to retrieve point attribute information will cause the interface to log an error message and then shut down.

   • cachepath

     Specify the cache file path.

   • cachesynch

     Specify the cache file synchronization interval.
