“SIMATIC S7-1200, S7-1500 Channel” channel DLL
Symbolic addressing and loading of AS symbols
WinCC V7.3 offers an improved configuration of the communication via SIMATIC controllers
S7-1200 and S7-1500.
You can configure tags in WinCC with optimized block access to the address area in the
automation system.
For this, all available controller data are downloaded to the “AS Symbols” tab. The needed
symbols are integrated into the Tag Management.
You have the option in Tag Management to configure offline without being connected to the

Encrypted communication in the distributed system
SSL communication in distributed systems
WinCC V7.3 offers increased security for communication:
WinCC offers encrypted communication of connected computers in distributed systems.
You specify a PSK key for the computers in the “Simatic Shell” network management. This
means that only those computers in which the shared specified key is known prior to
communication communicate with each other. You can specify different environments in a
network each with its own PSK key.

Benefits compared to the configuration client
● The configuration computers do not have to be entered on the server.
● You do not need to configure user authorizations in the User Administrator.
● The project engineer can edit all types of WinCC projects:
– Single-user project
– Multi-user project
– A client with its own project
● You can only activate Runtime if the project is on the local computer and has not already
been opened by another computer. Accordingly, the project can no longer be opened on
another computer when Runtime is activated.

Extended functionality for WinCC Graphics Designer
Graphics Designer
WinCC V7.3 offers the following new functions in Graphics Designer:
● “Process pictures” selection window:
– All pictures and faceplates from the “GraCS” project folder are displayed and can be
filtered with file filters.
– Pictures and faceplates inserted with drag&drop are automatically set up as
preconfigured buttons or faceplate instance in the process picture.
– Use <Ctrl+C> to copy the list of pictures to the clipboard.
● When saving a picture, the “Output window” viewlet shows information, errors and warnings
for the configuration. When you double-click a message in the output window, for example,
the corresponding picture object or the property of the object containing the affected script
is selected.
● Multilingual configuration of object properties: You enter texts in all configurable languages
without switching the language in the “Text Input” dialog. For configurable languages, the
configured languages are available in the “Text Library”.
● New object properties:
– “Display name” specifies the user-defined name of the process picture.
– “Web-enabled” identifies the process picture or faceplate type as executable in the Web
browser. The pictures are saved in “*.rdf” format in addition to “*.pdl” format and can be
used in the WinCC/WebUX option.
– “Scaling mode” for customized objects specifies how the internal objects of the
customized object are displayed when the customized object is scaled.
– “Scaling mode” for faceplates defines the size in which the objects of the faceplate
instance are displayed in proportion to the faceplate type.
– “Directory for pictures” with the extended status display specifies whether or not a
subdirectory for pictures is created. If pictures are stored in the subdirectory, they are
available for the extended status display.
● The “Date/Time” output format is now available for the I/O field.
● Direct2D is used to display the graphics. Soft shadows are displayed. For performance
reasons, you can disable the Direct2D display for individual computers in the computer
● You can use SVG files as background picture of a process picture and as picture for the
Graphics Designer objects “Button”, “Round button”, “Graphic object” and “Status display”.

● Colors and color palette:
– The new color palette matches the colors of the Microsoft standard programs.
– You assign different colors to individual object properties with a click of the mouse and
with additional keys.
– A bar is displayed in the font palette when a color is selected from the central color
● With the extended status display, you can also use pictures from a subdirectory of “GraCS”.

Easier configuration with WinCC Configuration Studio
Efficient engineering
The “WinCC Configuration Studio” editor replaces a large number of the previously used
editors in WinCC V7.3:
● Tag Management
● Tag Logging
● Alarm Logging
● Text Library
● User Administrator
● Horn
● User Archive
This means WinCC offers a uniform configuration user interface for all important project data
which is easy to operate.
The table-based editors make it easy to create and manage user data, connections, tags,
archive data as well as messages and project texts.
Simple operation
The user interface is divided into two areas: a navigation area similar to Microsoft Outlook and
a data area similar to Microsoft Excel. This means that the editor offers advantages in operation
which will be familiar to you from spreadsheet programs.
The clearly structured navigation area and the sublevels displayed on tabs provide easy
navigation and orientation in the editor, for example, in Tag Management when configuring
connections, groups and tags.
The “Properties” window provides a clearly structured overview of the properties for each
selected object. The configuration of a property is supported by the detailed help in the
information box.
Processing of mass data
WinCC Configuration Studio also provides a simple and efficient means of configuring mass
data for WinCC projects.
WinCC Configuration Studio therefore replaces the previously used editors: The functions of
WinCC ConfigurationTool and WinCC Archive ConfigurationTool are now integrated in WinCC.
You can still process project data outside of WinCC by exporting and importing the data.
Easy migration to WinCC Configuration Studio
To import existing files from the WinCC Configuration Tool or WinCC Archive
ConfigurationTool into the WinCC Configuration Studio, use the menu command “Import” in
the WinCC Configuration Studio. In addition to the file name, select the “ConfigTool file (*.xlsx)”
or “Archive Config Tool file (*.xlsx)” entry in the file selection dialog.

Multiuser engineering in WinCC projects
Multiuser engineering
In all WinCC project types, several users can edit a project simultaneously from different
Up to WinCC V7.2: Configuration client
Prior to WinCC V7.3, you could only edit a project simultaneously via remote configuration
from several configuration clients. These client computers had to be entered on the server for
this purpose.
As of WinCC V7.3: Multiuser engineering
WinCC V7.3 supports efficient engineering through more flexibility in a team of project
engineers in addition to the configuration client.
On the “Options” tab, select the check box “Multiuser engineering” in the project properties.
This gives all WinCC users access to the project data within the limits of their authorizations.
Simultaneous editing is prevented by locking opened resources.
You can find more information in the section “How to use multiuser engineering”.

Excel Workbook Wizard
The “Excel Workbook Wizard” offers the following improvements for configuration:
● For Excel worksheets, you configure the display of archive values and messages, for
To do so, you specify the display properties. You can now save the property settings in
templates. You can then load the settings and use them again after exiting and restarting
● For the display of archive values, you can now define the unit of time with user-defined data
● The settings for the time span have been improved and expanded.
For the display of messages, you can now also configure the time span in relative or
absolute time format.
● If errors occur in the display of the Excel workbook or no connection to the WinCC server
is established, the log entries are displayed in a workbook. The entries contain the date,
the tags or messages affected, the server, and the error message.
You can now display static process pictures on a language-specific basis in the Web center.
This function is only available if you have configured and published pictures in different
languages. You will also have to have selected the corresponding language for the picture in
the picture administration and in the web part.
You can now simultaneously configure multiple time-triggered reports with various starting
times in the Webcenter. The starting and ending times can be before the report creation time.
For example, a report is created at 5 PM which contains values for the time between 8 AM
and 4 PM.

Web access with WinCC/WebUX with any browser
WinCC WebUX provides a solution for device- and browser-independent operator control and
monitoring of the automation system.
With WinCC V7.3, limited functionality for mobile end devices is supported initially.
The WinCC pictures are configured for WebUX access. The pictures are configured as
executable for the Web browser in Graphics Designer using the object property “Web-enabled”
and thus also saved in “*.rdf” format.
