When I run NI OPC Servers for more than 2 hours, the device automatically disconnects, and I receive the following error message:
Source: LicensingEvent: The demonstration time period has expired.
This error is shown below:
The NI OPC Server is not activated, and NI OPC Servers are installed by default with a temporary license for a two-hour evaluation period. You will need to purchase the OPC Servers License or, if you already have one, please activate it.
