WinCC Basic functionality
The Runtime application of the WinCC basic software offers all
essential functions of a powerful SCADA-System: On this page:
Integrated User Management
Using WinCC User Administrator, you assign and control users
access rights for configuration and runtime. As the administrator, you
can set up at any time - including at runtime - up to 128 user groups
each containing up to 128 individual users and assign them appropriate
access rights to WinCC functions. A total of 999 access rights is
possible.
Starting with WinCC V7 SIMATIC Logon is part of the WinCC basic
system.The user administration with SIMATIC Logon integrates into the
security system and user management of Windows and thus meets enhanced
security requirements according to FDA regulations..
SIMATIC Logon comprises a number of security mechanisms and provides a
plantwide user management

User Interface
Using WinCC standards, you can create custom configured user interfaces for any application
- for safe process control and optimizing your entire production:
- Comprehensive range of configurable standard objects
- Pushbuttons, Check- and Radio-Boxes and Sliders
- Grafical objects (Vector- and Bitmap formats)
- Tube objects (any path can be depicted)
- Application and picture windows
- OLE-Objects, ActiveX- controls (e.g.alarm, trend, table controls)
- Media Control (Animated GIFs, AVIs,support of .NET and XAML)
- Input- Output fields, text lists
- 2D and 3D bars, status and group displays
- Centrally changeable objects (faceplates)
- Online Language switching
In projects that have been created for several target languages you
can switch between the languages online during runtime
- Menus and toolbars
Windows elements like menus and toolbars can be integrated into the
WinCC user interface. These new user interface elements can be
utilized in screens and screen windows, be configured "fixed" or
movable, and be operated in the familiar Windows manner.
- Applying of the Windows settings to the runtime application:
Concerning their depiction, all WinCC Controls and Windows objects
(buttons, scroll bars) within WinCC can be changed over together with
the Windows settings. In doing so, a central color palette can be
assigned to central design settings, which of course can be
individually customized afterward. Especially the Vista style effects
hover, glass, shadows, and transparency offer many possibilities.Altogether,
this enables a project-specific look & feel to be created for the user
interface.
- Zoom functions
WinCC makes it possible to represent screen sizes of up to 10 000 x 10 000 pixels using intelligent zoom functions.
The view of a process screen in runtime can be enlarged or reduced using the mouse wheel.
When the picture has been assigned a zoom factor, the mouse can be used for
panning. After clicking on the mouse wheel, a navigation compass appears.
Move the mouse pointer to scroll the picture in the corresponding direction. Using the
decluttering function layers, and the objects contained in
them, can be displayed and hidden, depending on the zoom factor.
Message system
SIMATIC WinCC doesn't just acquire process messages and local events, it
also stores them in circular archives and then makes them available as
desired on a filtered or sorted basis. Messages can be derived from
individual bits, can be a result of an alarm message frame directly from
the automation system or of analog alarms in the case of out of limit
conditions. Individual acknowledgement procedures, a freely definable
message structure and configurable archiving as well as logging of
messages are additional features.
In the WinCC Alarm Control, the depiction of the messages can be
individually customized. Extensive selection options, e.g., via a
user-specific filter matrix, assure an optimal overview. The depiction
of messages already swapped out is possible as well. At the push of a
button, the messages depicted can be exported or printed out as a
report. System-specific functions can be implemented via freely
configurable toolbar functions.

The message hit list indicates the average and total times that
specifi c messages have been pending for (message duration) and, in a
similar way, the average and total acknowledgement time.

With the function "Alarm Hiding", the operator suppresses unimportant
system status messages on the screen display, though they continue to be
archived in the background. The “Hiding List” can of course be viewed at
any time and individual or all alarms be displayed again by selection.

Archiving system
Historical values or value progressions are stored in process value
archives. Besides process values, WinCC also archives messages and
application data. The archiving occurs in ring archives in the
integrated, high-performance MS SQL Server database at a rate of up to
10,000 measured values and 100 messages per second. The storage capacity
requirements are very low due to powerful, lossless compression
functions. The WinCC basic system already allows up to 512 archive tags
to be configured. In the final capacity stage, PowerPacks enable the
expansion to up 120,000 tags. A central, optionally redundant, long-term
archiving can be implemented via a central archive server with the
option WinCC/Central Archive Server.In the Trend Control, current values (online trend curves),
historical process values, and desired value trend curves can be
depicted in the same trend display. The depiction of messages already
swapped out is possible as well. In doing so, a customized scaling of
the time axis and the value range can be performed (e.g., scaling in
percent). The time and value axes of the individual trend curves can be
moved online by mouse movement.
This function, for example, can be used for batch comparisons.

At the push of a button, integrated statistics functions enable the
determination of min., max., average, and standard deviation as well as
the integral calculation. A logarithmic depiction of trend curve
progressions is also possible. At the push of a button, the process
values selected (highlighted) in the Trend Control can be exported to a
CSV file or printed out as a report. In addition, system-specific
functions can be implemented via freely configurable toolbar functions

Reporting and Logging System
WinCC has an integrated logging system that you can use to print data
from WinCC or from other applications.This system prints data that was
acquired at runtime in configurable layouts by means of different types
of logs: from message sequence logs through system message logs and
operator logs up to user reports.Before printing reports, you can save
them as files and preview them on the monitor. WinCC logs can also
contain data from the database and external data in CSV format as a
table or a curve in a log.
Control technology functions (Basic
Process Control)
WinCC's basic system contains functional expansions that make a WinCC
station ready for process control tasks with a minimum amount of
engineering work. Basic Process Control offers additional objects and
configuration tools (e.g. the Picture Tree Manager) to allow you to
easily implement typical instrumentation and control technology
requirements.
- Group displays
- Screen division
- Picture hierarchy
- Lifebeat monitoring
- Control of external signalling devices
- Time synchronization via PROFIBUS or Ethernet.
