How to get your system uptime to the maximum.
- Redundancy
  The high availability requirements of plant constructors and operators as well as the process and data security can be covered with the redundancy concept of WinCC OA.
- Redundant network connections
  In order to achieve a better fault tolerance WinCC OA Managers can connect to other WinCC OA Managers running on different computers via redundant network connections (this means connecting through two network connections (= IP connection)).
- Alive mechanism of manager connections
  The alive mechanism in WinCC OA serves for connection controlling between the single managers. Each manager sends alive messages at definable intervals.
- Error tolerance and stability
  Continuous improvements are made concerning the error tolerance and reliability. This page gives an overview and description of the changes. Additional information can be found in the further chapters of the documentation.
- Kubernetes Health Check
  An introduction to health checks with Kubernetes for WinCC OA.
- Message Compression
  The message compression compresses WinCC OA messages. Data compression means encoding information using fewer bits than an unencoded representation would use through use of specific encoding schemes.
- Identification Caching
  The identification caching provides you an advantage especially when using remote user interfaces and distributed systems. Identification caching allows the identification to be sent as “delta” instead of the whole identification. Thus, only the changes are sent by the Data and the Dist managers.
Reporting
Create state of the art project reports without limits.
Addons

Reference Tables
Detailed and extensive content for special project adaptation.
