The licenses to any of the QuickOPC Product Options (such as Excel Option for QuickOPC) are always an addition to your base QuickOPC license. That is, to use any specific QuickOPC Product Option, you always need a QuickOPC license, and a license to that QuickOPC Product Option. Without the base QuickOPC license, the license for the QuickOPC Product Option is useless.

There is no specific Upgrade Assurance for QuickOPC Product Options. The Upgrade Assurance period of any QuickOPC Product Option follows the Upgrade Assurance period of the base QuickOPC license.

The trial license allows you to use QuickOPC together with all its Product Options. You do not need a specific trial license, if you want to try out any of the QuickOPC Product Options.
