Installation and Requirements

Requirements

The RDB compression is installed together with the RDB archiving since WinCC OA version 3.9 or higher. According to that the same requirements apply for the RDB compression (see Requirements for Installation).

Installation

The RDB compression is installed together with the RDB archiving since WinCC OA version 3.9 or higher (see First-Time Installation).

Upgrading existing projects

An upgrade is needed only when an older RDB installation (< WinCC OA version 3.9) is installed on the system.

As WinCC OA and RDB compression can be used in the same WinCC OA project, existent projects can be expanded by the RDB compression functionality. Once the corresponding upgrade files have been imported, the relevant panels, CTRL extensions and DB scripts are available and can be used without any other preparation.

See Upgrade of an RDB Project.

When updating a schema from version 8.1 to 8.5 the parameter reset_cs must be set to 'yes' in order to create the CS tables.

WinCC OA compressions are not adopted automatically to RDB compressions.
