## CLI Examples

Example of using [Data Agent](https://github.com/imubit/data-agent) CLI to access PI tags

```commandline

dagent exec create_connection --conn_name=pi --conn_type=osisoft-pi --enabled=True --server_name=DATA-SERVER

dagent exec list_connections

dagent exec connection_info --conn_name=pi

dagent exec list_tags --conn_name=pi

dagent exec read_tag_values_period --conn_name=pi --tags="['sinusoid', 'sinusoidu']" --first_timestamp=*-100h --last_timestamp=*

dagent exec copy_period --src_conn=pi --tags="['SINUSOID', 'sinusoidu']" --dest_conn=csv --dest_group='sinus.csv' --first_timestamp=*-100h --last_timestamp=*

```

## 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.
