- Disaster Recovery System
- 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.

Server KPIs

The Server section of the System Dashboard provides all key operational and hardware information about the current server instance. This enables efficient monitoring, troubleshooting, and documentation.

Overview: Server Widget

The Server widget displays all fundamental metrics of the physical or virtual host running your WinCC OA project. All specifications are updated regularly, enabling a quick assessment of the system environment and the early detection of anomalies.

Detailed KPIs

Host Name

The Host Name identifies the server in the network, e.g., VRA-TST-0037976. Useful for identification, troubleshooting, and remote access.

IP Address

Shows the IP Address of the active network connection, e.g., 10.2.40.252.

Clicking reveals further details:

Device Name: Network adapter label, e.g., vmxnet3 Ethernet Adapter #2
Interface Type: e.g., Ethernet0
IPv4: Assigned address
IPv6, SSID, Signal Level: Additional properties (usually empty except for Wi-Fi)

OS Version

Displays the operating system of the server, e.g., Windows Server 2022 Standard.

Clicking for details shows:

Platform: e.g., Windows
Distribution: e.g., Microsoft Windows Server 2022 Standard
Release Version: e.g., 10.0.20348
Architecture: e.g., x64

OS Uptime

Shows how long the operating system has been running since the last restart, for example 1 day. Short uptime can indicate reboots or maintenance activity.

PC Model

Hardware model of the server, such as VMware7,1 for a virtual machine or a workstation name for physical hardware.

CPU

Type of CPU in use, for example Intel XEON® GOLD 6548N. Relevant for performance and compatibility assessment.

NTP Status

Displays the network time synchronization status:

NTP Server: Used time server, e.g., atenteisetmdc03.etm-ag.com
Enabled: Whether time sync is activated (Yes)
Synchronized: Current sync status (Yes)
NTP State: State description, e.g., synchronized
Last Sync Time: Last successful synchronization, e.g., 22.10.2025 12:49
Server Time: Actual local server time, e.g., 22.10.2025 13:04

Note:

Viewing or updating NTP KPI information may require administrative rights. In some cases, a manual trigger of the windows time service using net start W32Time might be necessary.
