9.2.2 Single station and multiple station systems
An OS can be configured as a:
Multiple station system
Plant bus (ISO)
Terminal bus
(TCP/IP)OS Servers
AS1
OS Terminals
OS
Client 1
OS
Client 32
ES
ASx
Server 1 Server 12
Servers contain communication to the AS, pictures, logging of tags and messages.
Clients offer the user interface.
With a multi-user system, one or more (up to 12) OS Servers supply up to 32 operator
stations (OS clients) with data (project data, process values, archives, and messages)
via a terminal bus. The terminal bus can share the transmission medium with the plant
bus or it can be designed as a separate bus (Ethernet with TCP/IP).
In this architecture, redundant OS servers may be set up to meet higher availability
requirements. Critical applications are monitored by health check for software faults. If a
fault is detected, switchover to the redundant system is triggered. Synchronization of the
redundant OS servers takes place automatically and at high speed.
The broad colored arrows in the figure above symbolize the exchange of information
between the AS and OS resp. between servers and clients.
The OS Runtime is executed on the OS servers.
Central Engineering
Whatever is the configuration of system components, it is always the Engineering
Station to be the source of everything. All configuration data are loaded from the ES to
the target system. The figure above indicates this by thin black arrows.
OS Simulation
The OS runtime of servers must not be started on an ES station! To provide the
opportunity to test OS configurations on the ES in runtime without disturbing the running
OS server, the OS can be simulated on the ES.

OS
In single station system architecture, all operator control and monitoring functions for a
complete project (plant/unit) are concentrated in one station. This OS single station can
be operated on the plant bus together with other single-user systems or in parallel with a
multiple station system. Redundant operation of two OS single stations is also possible
(SIMATIC PCS 7 Single Station Redundancy).
Special case: Combined ES/OS
Plant bus (ISO)

ES
The PC station configuration of the ES contains the WinCC application for the OS
project. This is the only case, where the OS Runtime is executed on the ES.

9.2.3 WinCC Explorer / Location of the OS Project
After insertion of a PC Station with WinCC Application in the multiproject, you will find
the OS-project as you can see in the picture below:
Path to the storage location
depends on the multiproject
structure and how it was created.
All pictures of the
OS project are
located here.
The subfolder GraCS contains all pictures of the OS project.
You have to place pictures from other multiprojects in this folder first before you can
integrate them in your current OS project!
For editing the contents of an OS, the OS project is opened from the Component View
of the SIMATIC Manager: WinCC Explorer will be launched.

9.3 Plant Hierarchy Settings
Settings on the Plant Hierarchy level will control content of data on the OS systems.
Plant Hierarchy settings are relevant to the structure of pictures and names of tags:
HID (Higher level Item Designation)
Hierarchy folders that are included in the designation enter their names in the HID.
Hierarchy folders not included in the designation can be used to create additional
"drawers" (for example, for additional documents such as plant descriptions, process-
tag sheets, etc.).
When assigning names, please note that when you compile the OS, the tag name
must not be longer than 128 characters. The name consists of the folder names in the
hierarchy path, the chart name, the block name, the delimiter, and the I/O name.
With delimiter
A delimiter is appended in the HID to the name of the hierarchy folder. Delimiters are
used in the textual representation of the hierarchy path for clearer distinction between
the names of the hierarchy folders. The hierarchy path is the sequence of names of the
hierarchy folders through the hierarchy levels to the current object. The "" character is
used as the delimiter. Note: There is always a delimiter after the last hierarchy folder
that is included in the designation, which means this option cannot be modified.
OS area
This defines which hierarchy level is to be valid as the OS area level. Only the top three
hierarchy levels are available as OS area levels. The default is level 1.

The answer: Communication
Before it is possible to have communication between an OS and an AS, a connection is
to be set up between both stations.
It is done by NetPro:
The connection is configured between
• the WinCC Application on the PC (starting point of Insert New Connection dialog) and
• the CPU as its connection partner on the AS.

Named
connection
1. Select the WinCC Application object.
2. Because this object is capable to have a connection, the connection table is
displayed. Insert there a new connection.
13. PCS 7 System Course
SIMATIC PCS 7 – Basics Operating and Monitoring
Training Documentation, V1.00, ST-PCS7SYS 9 - 13
3. Select the connection partner. If you started with a WinCC Application, then the
CPU of the desired AS should be the partner.
4. Named connection: Assign a symbolic name to the connection between OS and
AS instead of the default connection ID as substitute for the connection parameters.
Use a meaningful name.
Named connection
This method of procedure is also designated as a "Named Connection". It is also
important for redundant OS server and OS simulation mode.
We recommend to use the name of the connected AS. Once the OS has been
compiled, this name will appear in the "SIMATIC S7 Protocol Suite" of WinCC tag
administration.

9.6 Compilation
9.6.1 Overview
A lot of settings to the OS data structure are done in SIMATIC Manager and the tools for
configuring the charts. It is stored in the Project database.
This OS relevant data is transferred into the OS database by a compilation process:
See [104] PCS 7 V8.0 Operator Station - Configuration Manual - 12_2011, 5.5.1 for
more details.
9.6.2 Settings
Settings for the compilation process are offered to you in dialog windows of a wizard:
Assign an OS area of the PH to an OS server.
Assign an S7 program to an OS server.
17. PCS 7 System Course
SIMATIC PCS 7 – Basics Operating and Monitoring
Training Documentation, V1.00, ST-PCS7SYS 9 - 17
• Area-oriented: With this setting, you assign an OS area of the PH to an OS server.
The advantage is that PCS 7 checks which data are relevant to the OS server. Only
these data are transferred. Default setting for PCS 7 projects from PCS 7 ≥ V 6.1.
• AS-oriented: With this setting, you assign an S7 program to an OS server. This
allows you to specify which OS accesses data on which AS. All the data of an
automation system is assigned to an OS server. This is the default setting for all
projects created with a PCS 7 Version < V 6.1.
See [104] PCS 7 V8.0 Operator Station - Configuration Manual - 12_2011, 5.5.3 for
more details.

Scope of the compilation
• Tags: The tags are created under the named connection, which has been set up for
communication between the OS and AS.
• Messages: Event texts of messages are stored in the text library. The number of
columns set up in the text library is based on the "Language for Display Devices"
setting.
• Units of measure, etc.: The character strings for units of measure, identifiers,
strings, and block comments are located in "Internal tags".
• Structure types: Corresponding to the use of specific block types in CFC charts,
these are created in the OS as structure types. The instances of these block types
are also managed at a lower level.
To define the scope of compilation the wizard needs some parameter more:
Runtime mode must be
stopped for a complete
download of the OS.
The OS servers (or single
OS station) can remain in
runtime mode during the
download procedure.

1. Delete all AS data from an operator station.
2. This function enables the picture jump function in WinCC-Runtime. The OS
comments will be amended by their interconnection partners. This function may
result in much longer mapper runtimes.
The box will only be visible if SFC visualization was enabled.
3. The "Minimum acquisition cycle" setting allows you to specify the shortest
acquisition cycle for archiving analog variables. For a new archive tag, AS-OS
engineering derives the following acquisition cycle from the processing cycle of the
block and the "Minimum acquisition cycle".
4. "Generate server data"
Select this radio button if you want to compile the variables of a server.
− The radio button is not selected as standard for compilation of changes. This
setting is not saved when you select the radio button.
− The radio button is selected automatically and cannot be deselected when you
compile the entire program.
Check your settings before you finish the wizard to start the compilation. The result of
the compilation is summarized in a log file.

9.6.3 Create/ update block icons
As one of the steps of the compilation process, the block icons are created/ updated.
Separate task
It can also be done as a separate task from the Plant View window of the project:
Precondition
Picture M110
As comparison…
Define how the tag
name is composed
Thanks to configuration in the plant hierarchy, the technological relationships between
AS and OS components are already known. This information can be used in the plant
hierarchy to automatically place and interconnect the ready-made block icons in the OS
pictures which have been selected for this purpose. Likewise they can be updated when
the block icons are changed.

Included levels
The charts are in
the 4th level
The picture is in
the 3rd level
PH level: 1 2 3 4
PH level: 1 2 3 4
Picture R310
In the Lower hierarchy levels included combo box, set the number of AS hierarchy
levels to be taken into consideration when creating/updating block icons.
The need for this setting is based on the different description depth between the AS and
OS.
On the AS side the charts are configured at process tag level. The charts are therefore
inserted at the lowest level and only contain the control modules with the drivers for
process connection. In our example the charts are at level 4.
On the OS side, the aim is different. The pictures do indeed describe the plant for the
lower levels in increasing detail, but not as far as process tag level. In our project the
lowest level for the pictures is level 3.
As there are no pictures at chart level, no block icons would be inserted by the
Create/Update Block Icons wizard either. This problem can be solved by setting
Lower hierarchy levels included to 1. The block icons are then simply inserted in the
pictures that are one level up.
The default setting is 1.

Ensure that all projects in a plant have uniform settings for the design. If you change the
setting of the design, check the visualization of self generated objects and adapt these if
necessary. You can define the appearance of the user interface in process mode by
selecting one of the two designs: WinCC 3D; WinCC Classic
The WinCC designs "Glass" and "Simple" are not supported by PCS 7.
• Design restrictions in Computer properties:
Some restrictions to the global design effects can be activated on the "Runtime" tab in
the "Computer Properties" dialog. You can improve the computer's reaction time by
switching off certain elements of the global design.
The settings made on this tab apply for all WinCC projects run on this computer.

9.8 Block Icons and Faceplates
9.8.1 Difference between Block Icons and Faceplates
Block Icons are there to represent AS functions in the OS.
In general, the main information (states and modes) of a device/function (motor, valve,
etc) is displayed in the Block Icon. PCS 7 therefore provides the corresponding block
icon for each technological block.
The block icons are automatically added to process pictures according to the plant
hierarchy and connected to the relevant process tag.
After a single mouse click on the Block Icon, a Faceplate may appear for:
− Showing more details in several views
− Operation to values (limits, suppression, etc) by several input fields, buttons…

Status displays
This area shows at the top the status (motor, valve icon,...) in the form of an icon or
symbol. Additional information and step functions are shown below it (buttons for
opening a faceplate of another block).
The additional information serves as support for the operator and it informs about the
status of the process instrumentation, e.g. whether a motor is simulated or maintenance
is carried out on it.
Buttons for additional faceplates
Additional faceplates can be opened via two freely assignable buttons in the faceplate.
Commands and operating modes
Modes and commands are displayed in this area and there they can be changed if the
required authorizations exist.
The following modes can be selected depending on the block:
• Manual
• Automatic
• Program mode
• Local mode
• Out of service
The commands can be "Start", "Stop", "Open", "Close", etc.
The selection of the mode and of the command is made through a separate operating
area which is displayed below the faceplate. This operator control can be made either
with or without confirmation, depending on the setting.
Interlocks
The different interlock functions are displayed in this section
Auxiliary values
Up to two additional analog auxiliary values can be displayed in the standard view of
some technological faceplates. They can be used e.g. with motors for displaying the
motor current and the coil temperature.
See [113] PCS 7 V8.0 Advanced Process Library - 12_2011, 1.3 for more details

Values, limits, etc can be changed from faceplates. A feature available only in APL is
that the operator enables and operator authorization can be graphically displayed. The
operator can distinguish which values can be changed and which can not be changed. It
can be distinguished whether:
• The operation at the block is generally blocked.
• The operation is blocked process-related.
• An operator does or does not have the appropriate authorization.
The value input also happens via a separate operating area below the faceplate. You
open this operating area by a mouse click on an adjustable value (white background
color). The value can be changed in the operating are in three ways:
• Via the direct operation, a value can be changed discretely using buttons (e.g. -2.5).
• Using the slider control, the value can be set to the desired value.
• Via the input field a value can be entered directly.
Via acknowledgement with “OK” the changed value is sent to the block.

9.8.5 User permission levels
Level 1
Depending on the user management
and access protection the operator has different
rights to operate a block in a plant/system area.
Level 2
Level 3
The following operator authorization levels from user management are used in the APL:
• Authorization level = 0
No process controlling, only monitoring.
• Authorization level = 1 (Level 5 in the "User administrator")
Process controlling (e.g.manual / automatic switchover, changing setpoint and
manipulated variables)
• Authorization level = 2 (Level 6 in the "User administrator")
Higher process controlling (e.g. changing limit values, control parameters and
monitoring times).
• Authorization level = 3 (Level 1100 in the "User administrator")
Highest process controlling (e.g.switching simulating on and off). This operator
authorization enables the following operation:
− Switching the simulation on and off in the parameter view
Simulating the values is authorization level 1
− Switching the release for maintenance on and off in the parameter view
• Authorization level = 4 (Level 1101 in the "User administrator")
Advanced operation 1 (free project-specific operator authorization)
• Authorization level = 5 (Level 1102 in the "User administrator")
Advanced operation 2 (free project-specific operator authorization)
Depending on the user management and the access authorizations instance-specific
authorizations can be assigned. E.g. all controllable blocks have the OS_Perm input
parameter, which allows you to implement individual operator control strategies by
setting the operator control permissions.

Associated values and direct jump to other faceplates
In the faceplates, additional faceplates can be called. Two assignable buttons are
available for this, in standard view and preview. The relationship between the buttons
and the faceplates is established via the inputs SelFP1 and SelFP2. The buttons
become visible and active if there is any connection to the block to be called. The
inscription is made on the block icon.
In several blocks' faceplates, up to two additional auxiliary values can be displayed, e.g.
motor speed. On the block, the value to be displayed in the faceplate can be switched to
the input UserAna1 or UserAna2. The visibility of the output fields is controlled via the
signal status.
The value identifier is defined as an indicator of the inputs, while the units possess their
own inputs.

9.8.6 Create/Update Block Icons
Block Icons are installed in pictures by the wizard „Create/Update block icons”.
This wizard can run:
• as one of the stages of the OS compilation
• separately from the Plant Hierarchy
In brief what the wizard is doing:
Finding OS relevant blocks in charts.
Identifying the Typicals file to be used as „icon library“
Finding the related block icons in the “icons library”
Copying the block icons in the picture
Assigning specific information to the block icon

@PCS7Typicals: “Icons Libraries”
The wizard Create/Update Block Icons makes copies from block icons as they are
present in “typicals” file as standard block icons:
@PCS7TypicalsAPLV8.PDL
• APL Versions before PCS 7 V8.0 delivered another Version of the APL “typicals” file:
@PCS7TypicalsAPL.pdl
• To remain the compatibility to former APL versions this older typical file is also
delivered in PCS 7 Version 8.0 under another name:
@PCS7TypicalsAPLV7.pdl
Each additional library also provides a template picture of this type with the required
block icons. The name of this template picture starts with "@PCS7Typicals" and also
contains a short library designation at the end. The template picture of the standard
library is called "@@PCS7Typicals.pdl".
The Create/Update Block Icons function uses these template pictures to insert the
block icons. All pictures whose names start with "@PCS7Typicals" are identified. These
are sorted alphanumerically in descending order and the top 11 template pictures are
used. A possible processing sequence might therefore be:
• @PCS7TypicalsRC.pdl
• @PCS7TypicalsBATCH.pdl
• @PCS7TypicalsAPLV8.pdl
• @PCS7TypicalsAPLV7.pdl
• @PCS7TypicalsAPC.pdl

Variants of block icons
Make your selection and specification of a Block Icon via the AS block's properties
dialog in CFC (Tab General”).
Block properties „Icon library“:
The OS compiler
(more exactly: the wizard “Create / update Block
Icons”) finds the related block icon by this number:
@TemplateAPL.pdl
In the case of automatic creation, all block icons in the picture which also appear in
@PCS7TypicalsAPLV8.pdl but were not generated via the plant hierarchy are
deleted. For manual configuration and when post-processing pictures, therefore, use
picture @TemplateAPLV8.pdl as the template for block icons, as the type property is
pre-assigned differently in this case.
Note the character @
in the type property.

Consistent Plant hierarchy
In order for this mechanism to work, the charts with the blocks that can be operator-
controlled and monitored must be located in the same path of the plant hierarchy as the
corresponding pictures.
If there are automation and PC stations in the same project, this should be an automatic
condition.
This is not the case if the components are distributed over several user projects. Here it
must be ensured that the paths within the various plant hierarchies are identical.
To compare the plant hierarchies in different projects, it is best to use menu command:
Options > Plant Hierarchy > Synchronize in Multiproject
The same series of block icons are present in the picture @Template, from where the
block icons can be copied freely to any picture, and have a connection to a tag structure
(AS block) using the Dynamic Wizard “Connect picture block to tag structure”.
