Description of the panel
On the left of the panel you see the host name
the WinCC OA project is running on, below the server symbol. The
"pie symbols" below the computer symbol show the free
disk space and RAM memory on the system. An information and configuration
panel for monitoring the hard disk/memory (see also Monitoring
the hard disk and Monitoring
virtual memory) is opened via left mouse click.
CAUTION
Note that the panel for monitoring the hard
disk cannot be opened on a remote system.
In the lower part of this panel the Data and Event
managers (DM and EM) are shown as well as their connection to
all registered managers (e.g. CTRL, archive, drivers). The tables
below the DM or EM contain detailed information on the registered
managers.
If the system is in emergency mode this is visualized
via the circle symbol of the DM with a red triangle containing
an exclamation point (for more information on the emergency mode
see chapter Data manager
emergency mode, basics).
Note
If you have started an API manager in your
project this is shown in the table "CTRL
and other".
Figure: system overview (Single
system) when RDB archiving is used

NOTE
When the RDB archiving is used, the RDB manager
is shown in the system overview. The ValueArchive 97 has to be
used for the configuration of the error weighting!
Further information and configuration pop-ups can
be opened via the Archive
as well as Control
and other tables. Via left mouse click on an archive
the action window for the specific archive is opened. The action
window allows to swap out and back up archives (see also Swap
out/backup archives). A left mouse click on the running CTRL
Manager shows an information panel with the CTRL scripts contained
in the pvss_scripts.lst
file.
The status bar in the lowest part of the system
overview panel displays the current user, date, time as well as
details on the user interface the panel was opened with. In the
figure above the details on the UI
show the following line:
Windows User Interface
#1 (EIWRK115)
The standard buttons Close and Online Help are located on the
right next to the status bar.
Configuration of the error
weighting
The Error state table on the right
side of this panel shows the error state on the computer.
Single system components can be controlled and
provided with a weighting in a system. The weighting is used for
the calculation of the error status in case of errors. Components
that are controlled and for which the error status is calculated
are e.g. managers, TCP connections, PLC connections, hard disk
capacity, RAM memory etc. The weighting is a number between 0
and 999 and the user can assign it specific to the components.
How grave the error is and which
number should be set for the weighting is defined by the user.
The loss of a PLC connection is e.g. configured with a higher
weighting than the failure of a UI. The error calculation is executed
in the CTRL script calculateState.ctl
(this script
is included in the
pvss_scripts list).
There is a panel for
the configuration of the weighting. The panel is opened via click
on the Configure
weight entry in the context menu. (Context menu is opened
via right mouse click on the Error state
table). This context menu can also be opened via right mouse click
on any table, button or symbol on the system overview panel as
well as by clicking the ...
button above the Error state
table.
Figure: Panel for configuring a
weighting in a single system

The configuration panel consists of the Manager and Data
points
tabs. The weighting
of single managers and weighting of arbitrary information on data
points is executed on these tabs.
Manager tab
The weighting for single managers in a WinCC OA system is configured
on this tab. The weighting is already configured for selected
managers by default. The configured weightings are shown in the
Manager
table. You can change the settings of a predefined manager by
choosing it or add a new manager with the desired settings to
the table. In case of errors e.g. manager cannot be started or
terminates, the configured weighting is included in the calculation
of the error status. Following settings can be set in the lower
part of this panel (Append/Update):
Manager: Choose the manager,
which should be added to the table and used for the error
calculation, from this combo box.
Number: Assign a specific
manager number via this spin button. If several UIs
were started with different numbers the number of the desired
UI manager that should be
monitored has to be set here.
Weight: Assign a number
to the weighting via this spin button (0-999 possible). You
have to decide how grave the error of a specific manager is.
This means which number is set for the weighting.
Alert
handling with alert class: If the error should not
only be shown in the system overview panel, activate this
check box and choose an alarm class from the combo box (default
is "060_alert").
An alert is shown in the alert panel in case of errors. By
activating this check box an alert handling is created (with
selected alert class) on an internal data point of type _ManagerConnections. If
an alert handling with an alert class is e.g. configured for
the operator station number 1 an alert handling is added to
the data point _Conn_event_0_1_to_ui_1_1.Link0
(the data point is automatically created when adding
it to the table of the monitored managers). This data point
contains an additional boolean element with the name Link1 in case that this
UI is provided with a redundant
network connection and this connection is monitored. The network
is monitored via the check box Monitor
redundant network. When creating a DP of type _ManagerConnections
the current status is not written on the DP elements.
First after change of the connection status the information
is set on the data point elements.
Temporary deactivated: By activating this check
box the set weighting of the manager is not included in the
calculation of the error status. If e.g. a periphery device/PLC
has failed and has to be fixed the monitoring of the driver
(the connection to the specific periphery) can be
temporary deactivated in order to not face the known
errors in the system overview panel.
There are options for setting filter criteria for
the sorting of the managers shown in the table. The options are
located next to the table at the top of the panel on the right
side:
Show regular weight:
Shows all configured managers
with their weighting.
Show weight 0: Shows managers
with the weighting 0.
Show inactive weight: (Shows
all managers whose weighting was temporary deactivated. This
means that these are not included in the calculation of the
error status.
Default sorting: Via this
button the set default sorting of the table is restored (Default
= sort by the column "Manager").
Example:
Add a manager with a weighting
Set your settings as shown in the figure (Manager
tab) above.
Choose a user interface from the Manager combo box.
Assign the number 5 via
the Number
spin button.
Assign the weighting 10
to the UI with the number
5.
Configure an alert handling
with an alert class in order to display an alert in the alert
panel in case of errors.
Activate the check box Monitor
redundant network.
In this example the
UI
with the number 5 is run with a redundant network connection
to the system.
After creating the settings
click on the corresponding buttons for applying the settings
in the table. Selected entries in the table can also be deleted
(see Default
buttons on configuration panels).
If a UI or CTRL
manager is included in the table and an internal data point of
this type does not exist, the data point is automatically created
(for UI: _Ui_*, for CTRL: _CtrlDebug_CTRL_*;
see also Internal
data point types for detailed information on these types).
Data points tab
The weighting for single data point elements in
a WinCC OA
system is configured on this tab. By default weightings are already
configured for data points that act as an indicator for too little
disk space or for too little virtual memory (see also Triggering
the emergency mode). The configured weightings are shown in
the table Data point limit check.
You can change the settings of a predefined data point by choosing
it or add a new data point with the desired settings to the table.
In case of errors e.g. hard disk full or connection of a driver
to the periphery failed (is also mapped on internal DPs), the
configured weighting is included in the calculation of the error
status.
Figure: configuration panel for
the weighting - "Data points"
tab

The functionality of this tab is very similar to
the functionality of the Manager tab. Following settings
can be set in the lower part of this panel (Append/Update DPE):
Predefined elements can
be chosen from the combo box for the connection state of some
drivers (connection to the periphery).
Other data point elements
can be chosen via the data point selector next to the combo
box.
There is a combo box and
a text field for selecting a relational operator as well as
for selecting a limit for the chosen data point element, below
the combo box used for selecting DPEs.
Weight:
Assign a number to the weighting (0-999) with this
spin button. How grave the error is (error of
exceeding the limit or how much the value falls below the
limit on the DPE) and which number should be set for the weighting
is defined by the user.
Example:
How to add a data point with a weighting
Create your settings like shown in the figure above
(Data points tab).
Choose the _Mod_Plc_1.ConnState
data point element from the combo box (the connection
status of the Modbus driver to the PLC with the number 1 is
shown on this DPE).
Set the relational operator
"==" and the limit
"0". This means that if this DPE is set to 0 the
configured weighting is included in the error calculation.
Assign the weighting 120
to this data point element.
After creating the desired
settings click on the corresponding buttons for applying the
settings in the table. Selected entries in the table can also
be deleted (see also Default
buttons on configuration panels).
After executing the steps of both examples (adding
a manager with a weighting and adding a data point with a weighting)
and an error occurs (UI with
the number 5 terminates and the connection to PLC 1 with the Modbus
driver is lost) the table Error state
in the system overview panel looks as follows:

All error statuses/weightings are summed and shown
at the top (130/350 - 130 is the sum of the weightings for all
upcoming errors and 350 is the sum of all configured weightings).
In the table below you see the single errors on the specific computer
with the set weighting.
Information and settings
of the UIs
The UIs are shown
at the top. The monitor symbols display the total number of connected
UIs in the system (the green
bar below the monitor symbols shows the connection status to the
Event manager). Also UIs that
were already connected and do not run at the moment are shown
(in this case the bars will be red).
Different settings and configurations can be executed
for the UIs. A panel including
general information like Start
time, User,
Display
(computer name on which the UI
is running ), IP
address of the computer for the chosen user interface and in the
lower area the host name (where the Event Manager is running)
resp. the connection (Link)
to the Event Manager (this information is read only), is opened
via left mouse click on a monitor symbol.
The green box next to Link
0 shows the connection of the UI to the Event Manager.
The meaning of a yellow box is that there is an alert handling
configured at the internal data point of the UI.

The Refresh button can be used to update the
status. The time of last refresh is shown in the panel.
A context menu, which allows to create settings
concerning the UI, is opened
via right mouse click on a monitor symbol:

The status of the UI
(run/stopped) is shown as the first entry, that is grayed out,
in the context menu. The entry Send standard "PING"
opens a terminal window and sends a standard PING command to the
computer, the UI is running on.
With this entry the network connection to the computer can be
checked (e.g. the connection to a specific computer can be checked
when the opening of panels takes long).
Send
message opens a another panel, which allows to send
a message to the particular UI
(this makes sense if you have to make maintenance works and want
to inform other users at the control stations).
The entry Statistics opens a panel, which
shows the message and DP statistics for the connection of the
Event manager with the UI (see
also Diagnostics
panels). This panel is also opened via left mouse click on
the Event and Data managers in the system overview panel (there
is a further entry Msg
statistic to <host2> available in this context
menu in a redundant system. Via this entry the message and DP
statistics panel for the connection of the Event manager on the
redundant computer is opened with the UI).
The selected user interface is stopped via Terminate
Ui #2 (before the UI
is deactivated you have to confirm that you want to close the
UI).
By selecting the last entry Configure
weight the error weighting can be configured (see also
Configuration of the error weighting
at the top of this page).
If a redundant system is in the split mode there
are two additional entries visible in this panel. Via this entries
you can switch the UI to Host1
or to Host2 (first redundancy partner or second redundancy partner).
The UI always sends to both events.
The UI is only switched in the
receiving direction (see chapter Redundancy
in split mode of the redundancy documentation for more information). |
