Siemens SIMATIC WinCC 8.1 Update 2

Siemens Digital Industries (DI) has released Simatic WinCC 8.1 Update 2 is a scalable process visualization system (SCADA) that is graduated by price and performance, with efficient functions for controlling automated processes.


Note: SIMATIC WinCC V8.1 is an independent product and a full version. SIMATIC WinCC V8.0 is still available as well.

In comparison to the direct previous version SIMATIC WinCC V8.0, the new SIMATIC WinCC V8.1 offers the following improvements and enhancements with regard to the range of functions (in addition to the consolidation of all previous WinCC updates):

1. Operating System
WinCC V8.1 supports the following Microsoft operating systems:

- Windows 11 (64-Bit) Professional, Enterprise
- Windows Server 2019 (64-Bit) Standard, Datacenter
- Windows Server 2022 (64-Bit) Standard, Datacenter
Under Windows 10 and Windows 11, the number of client connections within one server-client-system is limited to 3. With WinCC WebUX up to 9 connections to one web server are possible.
2. Upgrade Possibilities
WinCC projects from older WinCC versions can be implemented in V8.1 directly (no intermediate steps) as of WinCC V7.2 and higher.
In order to update existing WinCC licenses to V8.1, there are two upgrade levels available.
- Upgrade from WinCC V8.0 to WinCC V8.1
- Upgrade from WinCC V7.4 / V7.5 to WinCC V8.1
