11 Customizing the OS
11.1 Learning targets
The participant will learn about
• Possible mechanisms of operator authorization
and time synchronisation
• several ways to represent dynamics of values
and status in the AS
• The role and functions of the OS project editor
• The concept of the PCS 7 event-signaling system
and how to customize it
The participant will be able to
• configure operator authorization, picture
navigation, presentation of events and alarms

• configure an extended status display including
several status bits and the group value
11.2 User administration
11.2.1 Basic User Authorization Concept
User rights are administered in the "User Administrator" Editor of WinCC Explorer.
• Example: For an operator it is possible to operate valves Manual/Auto and
Close/Open, but changing the Monitoring Time is not possible (field is grayed out).
• Function: It is because this operator is not authorized for the related function.

PCS 7 System Course
Setting User Administrator
You manage and supervise user access rights in the User Administrator. The main task
of the User Administrator in runtime is to monitor system login and access rights.
In the editor "user administrator" two possibilities are available for managing user rights:
• WinCC Logon: creation of user groups/users and authorization assignment
• SIMATIC Logon: activate check box "SIMATIC Logon"; creation of user groups and
authorization assignment
The different OS areas and the plant structure from the SIMATIC Manager are shown in
the User Administrator. Some of the authorizations can be assigned area specific.
Users with the authorization
User administration have the
permission to open this window
also in OS-runtime to make
changes on the authorizations.
OS area specific
authorization
As of PCS 7 V8.0, 2 new operation levels are pre-defined in the User Administrator
being freely configurable:
• Extended operation 1 (No. 1101)
• Extended operation 2 (No. 1102)
Name and password
Users are identified by a name (4 characters or more) and a password (6 characters or
more).
 For more details see

[231] PCS 7 V8.0 OS Process Control - 12_2011, 5.4.7

PCS 7 System Course
11.2.2 Extended User Authorization Concept
Instance-specific parameterization
There is a new input field "Operation Level" (new attribute "Op_Level") at every relevant
operator-controllable input.
The numbers 1 to 5 are permitted inputs. They are assigned as follows:
• 1 = OperationLevel1_backup = Process Controlling (Preset in the block icon)
(corresponds to WinCC User Administrator „Level 5“)
• 2 = OperationLevel2_backup = Higher process Controlling (Preset in the block
icon) (WinCC „Level 6“)
• 3 = OperationLevel3_backup = Highest process Controlling (Preset in the block
icon) (WinCC „Level 1100“)
• 4 = OperationLevel4_backup = New: Extended operation 1
(WinCC „Level 1101“)
• 5 = OperationLevel5_backup = New: Extended operation 2
(WinCC „Level 1102“)
This permits instance-specific configuration that supports a detailed definition which
functions are available for a specific user (group).

Selection guide for WinCC Logon and SIMATIC Logon
SIMATIC Logon WinCC Logon
One time login is sufficient for several applications.
(OS, Automation License Manager, SIMATIC Manager, etc)
A client/server project with multiple OS clients is used.
One central administration for users/user groups is required.
Logon and logoff procedures are to be logged.
No central administration for users/user
groups is required.
We generally recommend that SIMATIC Logon is used, as it provides more benefits
than WinCC Logon and is not associated with any additional costs.
 If you run SIMATIC Logon with a logon computer, this computer must be available at
all times and must not demonstrate any excessive peak loads; therefore, we do not
recommend using the ES as a logon computer.
 The names of the newly created user groups must be written in exactly the same way
in the Windows operating system and the OS User Administrator. These names are
case-sensitive.
Users are only created in the operating system of the logon computer. Once a user
has successfully logged on via the logon computer, authorizations are then assigned
to that user in the OS.

11.3 Picture navigation
The pictures in the OS should be arranged in a way as it is done in the Plant View
window of the project (in SIMATIC Manager).
You can navigate in the OS pictures using navigation buttons or, select the picture
directly from the overview area.

Plant Hierarchy Setting
Pictures in the OS should be arranged in a way as it is done in the Plant View window of
the project.
A general presetting for the Plant Hierarchy is provided as default to control the
automated generation of the picture tree.
Picture order
The order of pictures in the same level can be set in the specific Hierarchy folder
properties:

PCS 7 System Course
OS compilation
At OS compilation the options to generate the picture tree is to be set as well:
Picture Tree Manager
The Picture Tree Manager in WinCC Explorer shows the arrangement of pictures.

PCS 7 System Course
All of the pictures of the WinCC project that
are still not assigned in the hierarchy and the
picture of an empty container are found in the
selection window.
Picture Tree Manager returns the hierarchy levels you created in SIMATIC Manager
under the same names.
At the bottom of the Picture Tree Manager, you will find all of the pictures that are not
inserted in the plant hierarchy. In the PCS 7 environment, these are the pictures that
you create additionally, because, for example, you want to display them in a picture
window of the process picture.
Picture Tree Manager and user permissions
The hierarchy levels of the Picture Tree Manager are also available when you assign
user permissions. You must make or change user permissions settings in if you create
new areas in the plant hierarchy of SIMATIC Manager. You must set new user
permission for these new areas.
 See [104] PCS 7 V8.0 Operator Station - Configuration Manual - 12_2011, 9.8.1 for
more details.

 ATTENTION!
Avoid any direct changes in the WinCC Picture Tree Manager, for example, do not
insert additional hierarchy levels or containers, or rename pictures. The data
visualized in Picture Tree Manager are derived from the configuration data of
SIMATIC Manager.
Subsequent changes can be overwritten when you recompile the OS, if you have
selected the "Derive picture hierarchy from the plant hierarchy" check box.

PCS 7 System Course
11.4 OS Project Editor
The OS Project Editor inserts pre-configured pictures, script actions, and tags in the
PCS 7 project. This editor also specifies the typical settings for a PCS 7 project:
There you make the settings for the user interface that the operator will use for
monitoring and controlling the plant in process mode. Following compilation of the OS,
the data you have already created in SIMATIC Manager will be transferred
automatically.
When an OS project is created in the PCS 7 ES, the OS Project Editor is called in the
background and initialized with default settings. If you want a configuration other than
the default configuration, start the OS Project Editor via WinCC Explorer and configure
your desired project settings.
You can conveniently transfer them to another OS using the Import/Export function in
the "General" tab.
You open the OS Project Editor in WinCC Explorer
Example
The overview area, on the top of the screen, contains a number of buttons representing
the areas of the plant. By default 16 buttons are present. The Project Editor can be used
to make adjustments to the buttons.
11.4.1 Layout
In the "Layout" tab, you configure the appearance of the runtime user interface.
To adapt a larger or smaller amount of areas, the number of buttons can be edited in
the "Layout" tab:

PCS 7 System Course
11.4.2 Area
In the “Area” tab, you configure the arrangement of the plant sections in the area
overview.
The “Area” tab of the Project Editor should be used to insert “empty buttons”.
Empty buttons can be used as placeholder for future extension or adapting a process
like arrangement of areas.

Access to areas missing authorization
In the User Administrator, you specify the area-specific access rights for users in
runtime. However, you can also allow users to select pictures and group displays of
areas for which they have no authorization.
Users without access rights to areas have the following access options:
• Picture selection is not possible. The user has no access to this area (standard
behavior)
• The picture can be selected using area button. The user can select the pictures of
these areas for monitoring purposes. Access to the group displays in the overview
and Picture Tree Navigator is not permitted. Area-specific messages are not visible.
Operator process controls with PCS 7 picture components are not possible, operator
inputs in process pictures depends on the configuration in the pictures.
• Picture can be selected using both the area button and the group display. The user
can select the pictures of these areas for monitoring purposes. Access to the group
displays in the overview and Picture Tree Navigator is permitted. Area-specific
messages are not visible. Operator process controls with PCS 7 picture components
are not possible, operator inputs in process pictures depends on the configuration in
the pictures.

PCS 7 System Course
11.4.3 Runtime window
In the „Runtime Window" tab, you configure the number and arrangement of the pre-
configured picture windows.
• Definition of the maximum number of windows which can be opened when calling
faceplates and trend displays.
• Definition of the maximum number of faceplates which can be opened on a monitor.
“Maximum number per picture module” means faceplates of the same instance. The
last faceplate opened is closed automatically when you open the next faceplate after
the maximum number is reached.
• Loop display mode for picture components. The windows are automatically adapted
to fit the size of the picture on opening. Their size cannot be changed. You can
configure the number and position of the windows. The loop display mode is not
relevant for faceplates of the Advanced Process Library but for the PCS 7 Standard
library.
• Group display mode for picture components and for windows in the function "Picture
by Name". The windows open with predefined dimensions which can be changed, if
you activated the "User defined" check box.
• Trend display mode for windows configured with the "Trend Online" function. The
windows are adapted to fit the size of the picture. Their size can be changed. The
configuration options are the same as for the loop display mode.

PCS 7 System Course
11.4.4 General
Activities when processed by project editor
In PCS 7 projects, you can change configuration data during operation using the
"Download changes" function ("Online delta download"). Every configuration change via
the user interface or programming interface is recognized by the runtime software and
accepted during operation.
You set this behavior for the OS Project Editor in the "General" tab. If the configuration
of the OS allows modification of data during operation, data that prevent a "Download
changes" function are brought into the project during the initial configuration. This
applies in particular for alarm configuration and the startup list. Each time the OS
Project Editor is run hereafter, only those configurations that do not prevent the
"Download changes" function are carried out.
In the case of a complete configuration, all settings are transferred again to the project.
Changes to configuration data during operation are lost in the process. You must
download the entire OS. After this, you can again switch on the delta mode of
"Download changes" in the "General" tab.
• Settings for the logs created in OS Project Editor
Printing or viewing the documentation of the current project configuration
• Execute the export/import of the current configuration settings in OS
Project Editor as a convenient way of integrating other Operator Stations in the
project

11.4.5 Message display
Settings for the following messages displays:
• Message filter
• Extended message line
• Authorization check of messages without area entry
• Manual hiding of messages (Smart Alarm Hiding)
• Sorting of message pages
• Creating the group display hierarchy
• Block comments of operating messages
Assignment of messages without defined area allocation:
Process control messages are not assigned to a specific OS area, for example. You can
select an OS area from the drop down list box to automatically assign these messages
to this area in for the active process.

PCS 7 System Course
11.4.6 Basic data
Definition whether to restore the factory state of the object. The list includes all project
objects which were changed after initialization of the basic data.
The default settings which were automatically activated in the course of ES engineering
configuration are displayed when you initially open the OS Project Editor.
The "Basic data" tab, however, forms an exception: The list entries change
automatically, depending on the picture and script configuration on the OS. You must
first confirm modified basic data picture files and actions in the "Basic Data" tab before
these data are accepted in the project.

11.6 Time synchronization
11.6.1 General principle
Process data are only evaluable, if all components of a process control system are
using the same time of day. Because that, all subsystems like OS and AS should run
with time synchronization.
The synchronization is basing on a master / slave architecture.
Two general synchronization modes can be distinguished:
• The NTP mode is suitable for PC Stations without own time synchronization
functionality. By the NTP mode, network components fetch the time from an external
NTP server. SICLOCK TC 400 is recommended as NTP server in PCS 7 plants.
• The SIMATIC mode uses an internal time synchronization functionality provided by
WinCC Software on OS Server Stations. Those OS Servers are able to work as
cooperative time masters.

PCS 7 System Course
11.6.2 PLC Clock Setting in OS Computer properties
Operating with Local Standard Time and Coordinated Universal Time (UTC)
In PCS 7, UTC is used internally as a rule within the system. Time information displayed
to the operator in process mode can be converted from UTC to the respective local
time. This makes it possible to configure a system, for example, with the automation
system in a different time zone than the operator station. If necessary, the plant operator
can also switch back and forth between coordinated universal time display and local
time display in runtime.
See the OS Computer properties below with its preferred settings:

PCS 7 System Course
11.6.3 Time Synchronization Settings in the WinCC Explorer
Time synchronization via the plant bus requires one of the following settings in the
WinCC project of the OS Server / Single station.
These settings have to be done in the Editor “Time Synchronization” of the WinCC
Explorer.
Select here the
network adapter (CP)
for the plant bus
 In our training project we do not cover the OS server / client configuration.
The settings of an OS Single station are similar to those of an OS server.
An OS client needs also settings in its WinCC project. As described in the
introduction, an OS client has to be synchronized via Terminal bus as slave. In
SIMATIC mode the client uses the time from a connected OS server (WinCC server).

11.7 Lifebeat Monitoring
The lifebeat monitoring function is used to monitor the functionality of all AS and OS of
the process control system. A process control message is generated if an AS or OS do
not respond to a lifebeat request.
Lifebeat monitoring is performed centrally from an OS that you have designated as the
lifebeat monitor. The lifebeat monitor monitors all OS servers, OS clients, and
automation systems.
You configure lifebeat monitoring in the "Lifebeat Monitoring" editor of the WinCC
explorer.
Requirements
• The hardware configuration and network connections for all automation systems and
operator stations have been configured in SIMATIC Manager.
• An OPC connection is created in WinCC Explorer for each operator station that you
wish to monitor.

11.9 WinCC Basic Objects and special additional for PCS 7
WinCC is the platform for the visualization of your plant. WinCC is supporting you by
several types of objects and object libraries.
Graphics Designer
The Graphics designer (an editor in the WinCC explorer) is the entrance to the process
pictures. Here you can edit the process pictures of your plant as files of type .pdl. By this
editor you also find all pictures, you created before in the plant hierarchy of the SIMATIC
Manager as place holder (for instance Reactors.pdl).
11.9.1 WinCC objects and libraries
Process pictures consist in single objects beginning from simple graphic standard object
like circle, rectangle, polygon to individually preconfigured smart objects and controls
which are connected with the process and with interface for input / output of process
values.
In general we distinguish between static and dynamic objects.
 See [104] PCS 7 V8.0 Operator Station - Configuration Manual - 12_2011, 8.8 for an
overview of dynamic PCS 7 standard objects.

the polygon function is available for tube connections.
Controls The 'Controls' tab contains as standard a selection of the most important ActiveX
controls provided by WinCC. Other controls can be linked.

PCS 7 System Course
11.9.2 How to make object properties dynamic
There are several options for dynamic updating of objects inserted in a process picture:
Tag connection
Simply interconnect objects, for
example, with the I/O of a block
instance of a CFC chart.
Direct connection
A link is established between objects.
Parameters only have to be assigned
for the source object; then connect this
source object to the target object.
Dynamic Dialog
You can formulate the dynamic
updates using tags, functions and
arithmetic operations in an expression.
You can define specific value ranges.
VBS Action C Action
A script action is created by linking an event, such
as a change in a binary tag, to a function which is
programmed in ANSI C or in Visual Basic. This
function is activated by an event or cyclically.
A script action is normally linked directly to an
object property which is also influenced by the
action. For example, a C action can be used to set
the color of an analog value, depending on a tag.
Options for
dynamization
of object
properties
Tag triggers and OS Runtime performance
Triggers are used to execute actions at runtime. To do this, a trigger is linked to an
action, forming the triggering event for calling the action. Actions without triggers will not
be carried out.
Cyclic triggers are a means of processing periodic actions in
WinCC. In the case of a cyclic trigger, the action is executed
when the trigger event occurs, e.g. every 20 seconds.
Value
Time
Trigger interval
Tag triggers consist of one or more specified tags. The action which
is connected to such a trigger is executed if a change in the value of
one of these tags was detected when the query was launched.
Value
Time
Query interval
Event-driven triggers: Actions which are connected to an event are
executed whenever this event occurs. Events can be, for example,
mouse control, keyboard control, or changes in focus.

Move cyclic computing tasks into the AS and
don't execute them on the OS!
Tag triggers should be used for a high performance level.
Extensive C / VBS actions increase the system load with a
negative influence on picture-call times in runtime.

11.9.3 Tag Connection – Working with the Tag Selection Dialog
After the OS compilation, process values of the SIMATIC Manager database are
available in the WinCC Tag Management. You can link an attribute of the object
properties to a tag using the Tag Selection Dialog.
Application example
The bar display in a tank is to be linked with the process value of the tank level.
Bar displays have a
reduced configuration dialog:
The attribute to be linked is
already predefined.

11.9.4 Dynamic Dialog
In Dynamic Dialog you formulate an expression by using tags, functions, and arithmetic
operands. The value of the expression, the status as well as the quality code of tags
used within the expression is used to form the object property value in Runtime.
The Dynamic Dialog may be used to map the value ranges of a tag into colors,
monitor/map single tag bits or Boolean tag value onto colors or texts or monitor tag
status or tag quality code.
Application example
Change the color of a bar level display depending on an activated simulation mode.

Direct connection can be used as a reaction to events. If the event occurs in Runtime,
the 'value' of a source element (Source) is used for a target element (Target).
The advantages of direct connection are the simple configuration and the time response
in Runtime. Direction connection has the best performance of all dynamization types.
Application example
This example shows a configuration of a button to transfer a predefined setpoint to the
temperature controller as internal setpoint by one mouse click.

11.10.1 Overview in Runtime
You created a hierarchy corresponding to your plant structure. Even in a process picture
that only displays a general overview of an entire plant, the operator requires
information from the process tags located in pictures from lower hierarchy levels. You
can map this information by means of group display: The group display outputs states in
color code (e.g. alarm, warning).

11.11 Alarms
11.11.1 Basic Concept of the Event-Signaling System
Origin of a message
Messages can originate in different locations within the control system depending on the
configuration. The time stamp of the message is influenced by where it originates.
The illustration below shows an example with a distributed I/O, ET 200M.
Single Station OS
PROFIBUS DP
ET200M
SIMATIC S7-400 AS
1. Origin of a message in the operator station
2. Origin of a message in the automation system
3. Origin of a message in IM 153-2
Plant bus (Industrial Ethernet)
Events which originate in the AS (2) or in the ET 200M (3) are transmitted as individual
messages to the OS via the plant bus. The message is transmitted along with the
corresponding time stamp. The messages appear in chronological order, with the time
they occurred, in the signal lists of the OS.

PCS 7 System Course
Event-signaling classes
Process control signals
Detected errors in PCS 7 own
components (AS, OS, etc.).
Process control signals are
generated by the driver blocks
in PCS 7 and do not have to be
configured.
Such errors range from failure
of a component to a wire-break
signal for a connected I/O
module.
Process signals
Process signals indicate
process events that take place
in the automated process, such
as limit value violations and
event signals.
Events signals are a subgroup
of process signals. They signal
process variables which serve
to evaluate a technological
variable, such as an elapsed-
time counter.
Operating messages are
generated when an operator
controls process variables, for
example, changes the
operating mode of a controller.
Operating messages are
generated automatically when
you use the faceplates which
are provided by the PCS 7
Libraries.
Operating messages
System messages
System messages are all messages that are generated by the SIMATIC PCS 7 system.
Loop in Alarm
Process and control technology messages from technological blocks which are
visualized on the OS feature the "loop-in-alarm" function. You can use this function to
select the faceplate for this process tag straight from the signal list.

11.14 Suppressing and Locking of Messages
Suppressing messages in CFC
The MsgLock = 1 parameter is used to selectively suppress the following messages
depending on Feature bit 25:
• All messages at the block or
• All messages at the block, except for process control messages, the message class
of which is disabled by default (for example, CSF, motor protection, feedback error)
and external messages.
Messages already queued received the "outgoing" status with MsgLock = 1.
Locking messages in the faceplate
The "Lock/unlock messages" function for individual message-capable blocks and all
message-capable blocks in an OS area is used when the plant operator wants to lock or
unlock all messages of a message-capable block or all messages of all message-
capable blocks in an OS area.
Messages generated at locked blocks in the automation system are neither displayed
nor archived in group displays in the process control.
The disable operation performed by the operator is recorded in the operator activities
log. The status of the disabled messages is visualized in the group display and in the
overview area using the group display hierarchy.
All queued messages are suppressed and are not displayed in the message window of
the faceplate. The "Lock message" icon in the toolbar of the faceplate changes to the
"Unlock message" icon. All four fields of the group display in the faceplate are displayed
with a white "X" on a gray background.
Pending messages for this faceplate are no longer displayed in the incoming alarm list
of the message system.

PCS 7 System Course
Operator authorization for the locking of messages
The required operation level for the locking of messages is pre-defined with:
• OperationLevel1_backup (in the WinCC User administration „Level 5“)
As of PCS 7 V8.0, the operator authorization for the button "Lock message" can be
defined with an internal variable @LockMessageAuthLevel). The configuration is made
with the numbers 1 to 5, applying to the respective Administration levels 5, 6, 1100,
1101, 1102. This setting applies for a complete OS project.
The configured operation level must also be defined in the block icon or in the faceplate
of the measuring point (e.g. higher-level process controlling) as otherwise operation will
not be possible.

11.15 Smart Alarm hiding
11.15.1 Overview
The alarm management in PCS 7 offers the “Smart Alarm Hiding” function from V7.0 on.
This function allows hiding of alarms to reduce the number of messages during process
operation (avoiding „flurry of messages“).
“Smart Alarm Hiding” offers the two following options to hide alarms:
• Hiding and showing alarms manually
• Hiding and showing alarms automatically
Behavior/Features
The behavior of the “smart alarm hiding” in process operation is implemented as follows:
• The messages are hidden in the following alarm lists: incoming alarm list, outgoing
list, acknowledged alarm list and one line (except alarm journal, process alarm list,
operation list) and the group displays.
• During process operation you can manually hide the following lists:
− incoming alarm list
− outgoing alarm list
− acknowledged alarm list
• Currently pending messages which are hidden are displayed in the “list of hidden
messages” (except: gone messages).
• The “messages to be hidden” list contains all messages to be hidden upon arrival.
• Hidden messages can be made to reappear in the incoming alarm list or outgoing
alarm list via the “list of hidden messages”.
• Hidden messages are archived.
• If operator stations are redundant, the message archive is updated.
• The acoustic signaling (horn) of hidden messages is suppressed /acknowledged.
• The status of hidden messages is not displayed in the group displays of the process
pictures and faceplates.
• Manually hidden alarms are redisplayed after a defined time.
• Manually hidden alarms are acknowledged automatically.
• Manual alarm hiding is OS server specific.
• An operator message is generated when the operator hides and shows alarms
manually.
• When hiding and showing a message, a message with the status show or hide is
generated.

11.15.2 Automatic Alarm Hiding
Plant conditions
Operating states
for hiding
• The definition of plant conditions is using enumerations which are defined in the
Shared Declarations in SIMATIC Manager’s component view. To do this, an
enumeration with the name "Operating State" is configured. Values from 1 to 32 can
now be defined as plant conditions in this enumeration. The value "0" is the
presetting for a "normal" plant condition. In this state the plant is within normal
operating limits and no alarms are hidden. You can now assign any plant conditions
to the values 1 to 32.
• In a multiproject consisting of several subprojects, the operating states are created in
the global declarations in the master data library and then updated in the multiproject.
 The enumeration can of course also have a name different than "Operating State".
However, this enumeration must be explicitly selected in the properties of the
"StateRep" block. The enumeration "Operating State" on the other hand has been
preset.

PCS 7 System Course
Logic to determine the operating states: STRep block
The technological block STRep converts Boolean input signals into the corresponding
operating state. Interconnect the state inputs of the STRep block to a logic that
determines the desired operating state.
More than one
status is active
The STRep block features 32 "StateX" Boolean inputs. These inputs correspond to the
values of the enumerations you have created in the first configuration step.
Block group
STRep block
Other
technological
blocks that can
generate alarms.
One technological area is composed of several technological blocks that can generate
alarms. To hide alarms for sub plants, you must combine all technological blocks of a
sub plant as one block group under an identifier (e.g. “MT”, “MaterialTanks”…).
All the blocks which are combined in a group are controlled by a STRep block. This
means that several STRep blocks have to be used where necessary to represent
several sub plants.
If the technological blocks of entire technological areas of a block group are assigned,
then this assignment is best made in the PO view.

PCS 7 System Course
“Hiding Matrix”
Process states
In the next configuration step you configure the “Alarm Hiding Matrix” in the PO view.
Here you can define which alarms of the group’s message capable blocks to hide for
which plant condition of the corresponding block group.
 You facilitate the work by filtering the display in the process overview to the block
group currently to be configured. You filter according to “Column -> Block group” and
enter the name of the block group in “Display”.
Besides configuration in the process object view, you can also export the data to
CSV, edit (e.g. in Excel) and re-import them.

By hiding alarms manually, the operator can put those alarms out of sight which are
irrelevant for the present operating state.

PCS 7 System Course
Manual alarm hiding is OS server granular. If an alarm is hidden manually on an OS
client, this alarm will neither be visible on any client accessing the associated server.
 Both, the changing of the hiding time as well as the display of the button for manual
hiding are delta download-capable.
