PI APS Connector for GE XA21
The PI APS Connector for GE XA21 can not handle digital sets from GE XA21. This makes the Automatic Point Sync only semi automatic, You need to load the digital sets maually while Points are updated automatically. If the APS can transfer digital sets the tool becomes automatic. In my case a non automatic APS is not useful so we need to implement a manual process.

PI APS Connectors are outdated. They use both PI SDK and the PI Module Database, which are both deprecated. Maybe the solution to this problem is not to fix the PI APS Connector, but to use a different PI product entirely (PI Connector For OPC UA?).
