The system can seamlessly use the OSIsoft PI System as the historian provider. In this situation, it is not necessary to define any Historian configuration. If the tag is mapped to an OSIsoft PI point, the system will automatically call the PI Server to get the data when trend charts are plotted trend or for any script or display methods that require historian information.
The system can work with both the PI System and the built-in historian at the same time. When historical information is requested for a point, either from trend charts or scripts, the system will first look for that information on the built-in historian module. If it is not available, it will try to find the data on the PI server. For information on connecting to the PI Systems, see Solution Import Tags.
