Variables Add-in for RTXHDB

Variables Add-in for RTXHDB is an Add-in for Microsoft Excel. It is a powerful but easy-to-use package for building Microsoft Excel workbooks for data analysis and report building. It allows, by tag name, direct link (DLL) access to all real time and historical values in the historical database(s). Permits on-line updating and scrolling, within Excel, of all tag values in all historical databases.

It has a Paste Variables dialog, which pastes information into the Worksheet cells as DDE Server Links or Report Builder Data Request Cells. Also, it can paste ASCII Text values, and allow Direct In-Line (DLL) functions to directly access the RTXHDB databases. This powerful set of Direct In-Line (DLL) functions can be used to specify information, from any accessible RTXHDB database or variable within any of the databases. The Variables Add-in for RTXHDB, in addition to its stand alone direct access to the RTXHDB databases, is also an ideal companion to DDE Server for RTXHDB and Report Builder for RTXHDB.
