Demo mode

You can install the Communication Driver without a license. The Communication Driver runs without a license in Demo mode for 120 minutes.

While in demo mode the Communication Driver checks for a license every 30 seconds. At the end of 120 minutes:

• the Communication Driver stops updating items.

• all non-system items have a Bad quality status.

• new items are rejected.

After 120 minutes, if a license is not found, it logs a warning.

You can use the $SYS$Licensed system item to check the status of your license. This item returns true if the proper license is found or the Communication Driver is in demo mode (120 minutes), otherwise, it returns false.

When a valid license is found, it stops looking for a license, and begins running normally. For more information, see the AVEVA™ Enterprise Licensing Help.
