The ADS is a Metasys server running on a computer that has a supported Microsoft® Windows® operating system and two specific components. The first component is the relational database management system using a supported edition of Microsoft SQL Server® Express software to store collected trend data, audit trail messages, and alarm and event messages with operator annotations. The second component is the web server software that provides SMP UI and Metasys UI access to data and routes commands to the Metasys system.
The ADS also supports the following:
- a greater number of engines as a Site Director than an engine supports
- multiple, simultaneous international languages at the user interfaces
-
allows a greater number of simultaneous users than is supported by an engine
-
provides added storage for memory-intensive Metasys features, such as User Graphics
The ADS-Lite is a specialized offering that enforces specific localized market connection limitations to other Metasys devices such as ADSs and engines.
