Troubleshooting

OSIsoft.AF.PI.PITimeoutException when reading historical data

Increase the SDK data access timeout settings on the client machine. There are two timeouts for the SDK, a connection timeout and a data access timeout. The connection timeout default is 10 seconds. The data access timeout is 60 seconds. Data access timeouts are the most likely cause of the error.

• Launch AboutPI-SDK.exe.
• Navigate to the Connections tab.
• Select the PI Data Archive in question.
• Increase the Data Access Timeout and Connection Timeout to 120 seconds or more.
