System Errors and PI Errors


System errors are associated with positive error numbers. Errors related to PI are associated with negative error numbers.

Error Descriptions


On Windows, descriptions of system and PI errors can be obtained with the pidiag utility:

\PI\adm\pidiag –e error_number

Appendix F: PI SDK Options


To access the PI SDK settings for this Interface, select this Interface from the Interface drop-down list and click UniInt – PI SDK in the parameter category pane.


Disable PI SDK


Select Disable PI SDK to tell the Interface not to use the PI SDK. If you want to run the Interface in Disconnected Startup mode, you must choose this option.

The command line equivalent for this option is –pisdk=0.


Use the Interface's default setting


This selection has no effect on whether the Interface uses the PI SDK. However, you must not choose this option if you want to run the Interface in Disconnected Startup mode.

Enable PI SDK


Select Enable PI SDK to tell the Interface to use the PI SDK. Choose this option if the PI Server version is earlier than 3.4.370.x or the PI API is earlier than 1.6.0.2, and you want to use extended lengths for the Tag, Descriptor, ExDesc, InstrumentTag, or PointSource point attributes. The maximum lengths for these attributes are:
