This field can be left blank if no password is assigned for the OSI PI user.
Note: If you change the PI Server name, user name or password fields, you must restart the collector service before the new configuration will take effect.
Note: If the username and password are provided with the PI Collector, it uses explicit login to connect to the PI Server. If the username and password are not provided, then we use the implicit login functionality of PI SDK. In this scenario, either it would look for PI Trust or PI Mapping to connect to the PI Server.
