The module provides the user with a mechanism to create WWW-pages, and can process other WWW-requests in internal OpenSCADA language, usually JavaLikeCalc, without involving low level programming. As a page processor, the module allows you to use standard DAQ-Templates. Using DAQ-Templates allows you to create WWW-page libraries and call them in this module multiple times as their implementations, as well as provide the data context of the template with their connection to the data of the subsystem "Data Acquisition".
