Information SIMATIC WinCC Unified: More than an HMI

SIMATIC WinCC Unified V16 is the new visualization system in the TIA Portal.

From machine-level operator control to integration of IT systems in automation, WinCC Unified is not only fit for today's demands but also for the demands of the future.

The system is impressive in its use of native web technologies (HTML5, SVG and JavaScript) as well as its high degree of openness thanks to high-performance interfaces for data exchange.

Key advantages at a glance

WinCC Unified has been completely redesigned and uses native web technology such as HTML5, SVG and JavaScript. This enables access to visualization from any modern web browser, without the need to install additional plug-ins. Configuration is performed in the proven TIA Portal.

WinCC Unified offers a fully scalable scope of functions, from the machine-level application to distributed SCADA systems.
HMI projects or project components can be transferred from a machine-level application to a SCADA application.

Due to its modern architecture, a wide range of functions can be executed by WinCC Unified in various environments. In addition to the classic "on-premise" application cases, it will also be able to run WinCC Unified in an Edge or Cloud environment.
In its initial version, WinCC Unified is available for panel- and PC-based solutions. Its use in the Edge and Cloud environment will be possible with a subsequent delivery stage.

Openness (Integration Platform)
Thanks to the interfaces integrated into the system, WinCC Unified offers a high degree of openness right from the start. 
By providing an open API interface, a WinCC Unified project can be automatically generated via the user's own application.  On the other hand, WinCC Unified features an API interface to enable extensive data exchange with other systems during operation of Unified. A new OpenPipe interface can be used to link external applications with a WinCC Unified.

SIMATIC WinCC Unified ES V16 - Notes for the engineering software

Note on licensing of engineering software
Every customer who purchases a license for WinCC Comfort V16, WinCC Advanced V16 or WinCC Professional V16, or receives it as part of the Software Update Service (SUS), can use the corresponding WinCC Unified Version free of charge.

License compatibility
A WinCC Unified ES can be installed together with a WinCC Advanced ES on a single computer via the installation. Valid licenses for a WinCC Unified ES can also be used for engineering of a WinCC Advanced (and vice versa).

A WinCC Unified ES cannot be installed parallel to a WinCC Professional ES on only one computer. Valid licenses for a WinCC Unified ES can also be used for engineering of a WinCC Professional (and vice versa). Licenses must be transferred to the WinCC Professional ES computer for this.

The following functionality is already included with the basic product

 User interface Scalable for all devices
 Connectivity Connects automation and IT via standard interfaces
 Alarming Know what is happening in your plant
 Reporting Plant reports (based on Microsoft Excel); minimum: MS Excel 2016 - Build 16.0.6769 (32-bit or 64-bit)
 Scripting Wide-ranging scripting options of Runtime
 Runtime Openness Extended functionality and integration platform
 Plant hierarchy Modular and standardized machine and plant designs
 User administration Local user administration and access control
 Client access

 Basic version provides licensed access by 2 clients.

Available options

Basic options

File-based loggingLocal data acquisition for small to medium applications
File-based logging is the standard logging variant and is activated by licensing logging tags. Up to 5,000 additional logging tags can be purchased for file-based logging.
The data-based logging option is needed for a higher number of logging tags or if long-term archiving is required; 

Parameter control

Uniform management and control of machine or production parameters

Unified collaboration

Assembling a distributed configuration


Flexible web-based, remote operation and control;
In addition to the two client licenses already included in the basic system, more access can be purchased in addition.
5 web clients can access a Runtime station simultaneously for non-server Windows operating systems. For more than 5 clients, a Windows Server operating system is required. 


SCADA options

Databased storageExtensive, high-performance, long-term archiving
This data-based logging option enables SQL-based logging.
Logging Tags must be purchased in addition for data-based logging. When switching from file-based to data-based logging, Logging Tags already purchased can continue to be used.

Requirements for a Unified Runtime station

Hardware requirements (PC systems)

The hardware equipment essentially determines the performance, especially for larger projects and visualization tasks, a powerful processor and more memory should be selected. Depending on the options used, e.g. Logging, additional free hard disk space is required.
