System overview

Increase your productivity with SIMATIC WinCC RT Professional

The WinCC Professional basic system is designed to be technology and sector-neutral, modular and flexibly expandable. It allows both single-user applications in mechanical engineering and complex multi-user solutions or even distributed systems with redundant servers and clients in plant engineering.

Efficient operations management

Manufacturing processes are becoming more and more complex against a background of ever increasing quality requirements coupled with fast product changes and frequent modifications. To ensure the highest possible productivity at the same time, it has to be possible to make prompt, target-oriented decisions regarding process optimization at all levels of a company. This requires an integrated flow of information across all operating levels and locations.
SIMATIC WinCC RT Professional provides you with high transparency and the basis for process optimization.  The intelligent use of information improves the processes in the company for a fast return on investment. This reduces costs, avoids waste, improves the utilization of production facilities and ultimately guarantees better efficiency and cost effectiveness for the company

WinCC WebUX allows for flexible operator control and monitoring of plant processes via the Internet or an intranet, especially using mobile devices (tablet PCs or smartphones). All devices with HTML5-capable browser are supported.
ONE monitor client is available without additional charge with the installation of the basic system as WinCC WebUX server.

The SIMATIC Information Server gives you transparent access to plant information at any time. Historical plant data can be simply compiled in web-based dashboards or reports without programming knowledge.

This ensures comprehensive access to plant information for each target group in the company (managers, quality assurance, maintenance) at all times.

Historical process information is saved as WinCC process value archives in the integrated, high-performance SQL database. 
500 archive tags are already licensed in the WinCC basic system; this number can be increased at any time through additive PowerPacks. . To reduce the amount of data for long-term archiving, the data can be compressed even further. To do so, the maximum value, minimum value or (weighted) mean, the sum or the difference is calculated for adjustable periods of time (e.g. day, month, year) and saved in compression archives.

In addition to automatic archiving, it is possible to add values manually to the archive or to modify archive values later with the appropriate authorization. This is required, for example, for laboratory values in some industries. For reasons of traceability, these values are marked as "modified manually" and the process is documented with an operation message.

In addition to local archiving on a WinCC server, additional central long-term archiving can be implemented with the SIMATIC Process Historian option

WinCC allows you to implement display languages in a simple and cost-effective manner. Thanks to UNICODE support, the display language can be changed at any time during operation. This is independent of the language set in the operating system. This means that it is possible to display multiple languages parallel to each other, such as message texts in European and Asian languages.
This makes commissioning considerably easier in international teams.

Efficient controls are integrated into WinCC process pictures for the display of current or historical data.  Process values can be displayed as a table or analyzed using a trend display.
The display is either predefined or can be adjusted individually by the operator, if authorized. Numerous means of representation guarantee the best possible overview.
The freely configurable toolbar functions also provide the option of integrating project-specific functions. f(x) trends, e.g. pressure/temperature, can also be displayed in addition to the time- and value-based representation.

The messages are displayed on the screen via the freely configurable WinCC Alarm Control. Here, the display of the message information can be adapted precisely to the requirements of the operator. The settings made can be saved in user-specific or global templates.
WinCC Alarm Control for the display of current/historical messages based on the contents of the individual message blocks can be filtered, selected and sorted, for example chronologically, by priority or by fault location, in the display. The contents can then be exported directly as CSV file or printed out as report. A freely definable toolbar function also offers a maximum degree of flexibility. For examples, project-specific functions can be integrated. To maintain an overview when there is a large numbers of incoming messages, unimportant operating messages can be suppressed from the screen display via an alarm hiding function. The hidden messages are then archived in the background.

Numerous integrated statistics functions allow a comprehensive analysis of process states. The message hit list shows how long certain messages were pending on average and in total (message duration) and similarly the average and the total acknowledgment time. Of course, the messages can be filtered here by relevant events, message locations and time intervals. This indicates quickly where critical points and bottlenecks in the production are located. To sort the messages in the message display for an evaluation, you can simply select the column heading and the required sorting criterion (for example, "Frequency, descending").

The timely recognition of faulty or incorrect modules and devices is essential for avoiding long downtimes. Therefore, constant monitoring of the plant is of the utmost importance. The TIA Portal provides support with its ready-to-use diagnostic mechanisms. No additional comprehensive configurations of the diagnostics are necessary. Activating the devices for the system diagnostics generates alarms derived from the configured plant layout in the "Devices and Networks" editor. These can be displayed in the HMI.

SIMATIC ProDiag is the fully-integrated TIA solution for machine and plant diagnostics. It saves the need for programming diagnostics in the CPU during the engineering phase and provides support for troubleshooting on the HMI. ProDiag makes it possible to monitor a machine or plant and to intervene in the event of a fault
The monitoring messages which can be generated for the various faults provide specific information on the monitoring mode, location and cause of the fault. Information on troubleshooting can be provided in addition. Plant operators can then not only recognize faults, they can also identify any potential danger in advance and take appropriate countermeasures.


From single-user system to web-based solution for all technologies and industries

To be able to meet growing requirements, the visualization must be expandable at any time without causing technology incompatibilities or requiring completely new configurations. Investment protection is a top priority.
SIMATIC WinCC provides the required integrated scalability, from the small single-user solution to the client/server solution and operator stations on the web. Redundancy solutions for highest availability and security can be built up as well.
In addition to scalable configurations, WinCC options and AddOns offer customer-fit extensions for technological and industry specific solutions

Depending on requirements, a WinCC single-user system can be expanded into a high-performance client/server system.  In this way, several coordinated operator control and monitoring stations can be operated together with networked automation systems.

The WinCC/Redundancy option gives the user the opportunity to increase the system availability by means of redundant WinCC stations or servers that monitor each other and, therefore, ensure the operability of the plant and allow seamless data acquisition.

WinCC WebUX offers flexible operator control and monitoring of plant processes via the Internet or an intranet, especially using mobile devices (tablet PCs or smartphones). All devices with HTML5-capable browser are supported.

WinCC/WebNavigator allows integrated operator control and monitoring of plants via the Internet or intranet without having to make changes to the WinCC project. Thin client solutions support the use of PCs and even rugged on-site devices and mobile PDAs.

The SIMATIC Information Server gives you transparent access to plant information at any time. Historical plant data can be simply compiled in web-based dashboards or reports without programming knowledge.

This ensures comprehensive access to plant information for each target group in the company (managers, quality assurance, maintenance) at all times.

The SIMATIC Process Historian archives any amount of data from different data sources of automation and the MES world and is the central long-term archive for production data.

Archiving in a high-performance SQL database in combination with efficient data compression mechanisms ensures that critical data will be available at any time in the future while using very little memory. 

Using standards for easy integration

SIMATIC WinCC all times stands for a high level of openness and integration capability because it is consequently based on standard technologies and software tools.
Starting with its first version it relies on the market leader in the operating system area, which offers additionally investment security. Using WinCC RT Professional (in TIA Portal), you benefit from the powerful SQL Server, integrated within the basis system. Moreover, it supports open interfaces to automatize the engineering as well as to merge automation and IT-World during runtime.


Using WinCC it is possible to realize connections and dynamic sequences without programming only by the use of standard dialogues. To realize more complex functions it is possible at any time to write scripts using VB or ANSI-C. Examples for such scripts are the conversion of values or the automatic start of reports or of individual messages.

When programming VB scripts you are supported by the use of a proprietary, comfortable editor with debugging support.
When using scripts you have full access to the properties of all WinCC graphical objects and to the controls as well as to the object model of WinCC and the applications of other manufacturers

Bidirectional flow of information from shop floor to top floor.

WinCC/IndustrialDataBridge is the flexible information hub between automation and the IT world. It reduces the complexity of interfaces and data formats

Cross vendor communication using OPC (OLE for Process Control)

OPC is used as a communication standard for a secure and authentic data exchange between applications within the industrial automation environment. It describes a series of specifications which are used manufacturer independent as an interface between different clients and servers as well as between different servers only. These include amongst other topics direct access to real-time data, the monitoring of messages and events as well as access to historical data.

Originally the OPC standard only was available on Windows operating systems. This standard was developed from OLE (Object linking and embedding) for Process Control. The new OPC UA spec which was introduced in 2009 describes a real universal connection. This standard is based on a secure, simple technology-independent platform which is future-assured and scalable as well as expandable for all challenges of the different company levels.


SIMATIC WinCC RT Professional offers by default:

  • OPC UA (DE,HA) Server 1.02
    Transfer of process values, archive data and messages of WinCC under the terms of the OPC UA specification 1.02 In addition to that a separate licensed OPC UA Server for the connection to the SIMATIC Process Historian is available.
