Updating the PI Adapter Credentials File
When using a PI Historian Connector the PI Adapter Credentials file contains the information required to connector to the target PI Instance. This file will need to be populated with information available from the customers IT department.
The PI Connector supports Kerberos and Basic Authentication. If Basic Authentication is used then the username and password must be populated in the properties file, for Kerberos Authentication these can be left blank.

| server_url | The required URL of the PI service | |
| username | The username to be used when connecting to the PI instance | |
| password | The password to be used when connecting to the PI instance for the specified user | |
