The SICAM PAS CC components extend the SIMATIC WinCC standard functionality by functions for the use of the control and display system in the field of power automation. SICAM PAS Wizard
The organizational functions of the SICAM PAS Wizard support you in the configuration of your project.
Import
After the creation of a station, you use the SICAM PAS Wizard to import SICAM PAS information configured and parameterized with the SICAM PAS UI - Configuration tool.
The import includes:
• Import of the SICAM PAS tags to the SICAM PAS CC tag management. • Import of the SICAM PAS messages to the SICAM PAS CC alarm logging. • Import of the SICAM PAS measured values and metered value to the
SICAM PAS CC tag logging.
• Creation of the SICAM-specific structure tags and of the required
internal tags (variables). Initialisation
The SICAM PAS Wizard initializes the project. Within the framework of the initialization:
• the SICAM symbol library is imported.
• the SICAM-specific alarm logging is created. • the SICAM text library is created.
The initialization can be performed independently of the SICAM PAS data import. In this way, you can start the configuration of the SICAM PAS CC project before the completion of the project via SICAM PAS UI - Configuration. The activities of the SICAM PAS Wizard are logged in the SICAM Report which provides you with detailed information on the success of the activities or on error messages and warnings.
SICAM PAS symbol library
The SICAM PAS symbol library includes
• Objects for the representation of the switching devices
• Objects for the visualization of measured and metered values
• Message window templates for alarm logging (templates for the event list, warning
message list and the protection message list)
• Control elements e. g. for the control of the switching authority, for synchronized
• Control elements for the control of the message list entries for defining which
updates of a process information initiate entries in the message lists.
Picture 14- SICAM Symbol Library
When creating your system diagrams, you simply move these graphical objects via Drag&Drop from the library to your diagram. As a next step, you connect them with the information parameterized via SICAM PAS UI - Configuration.
Switching device objects
IndustrialX Controls are used in SICAM PAS for the visualization and control of the switching objects. IndustrialX Controls can be used in the multi-client and Web n avigator environment.
The SICAM switching device objects for circuit breakers and disconnectors support four representation modes each:
• SICAM • DIN 42200 • IEC 445 and • LSA
If other representation options are required, you can assign the different states to bitmaps which have been defined for this purpose. The GIF image format ensures optimum display performance.
Bay overview objects
Bay overview objects are available in the SICAM PAS symbol library. These IndustrialX Controls visualize the switching status of the overall bay. During the pa rameterization, you select the individual switching devices for which the color is to change when the switching state changes. In this way, bay overview objects increase the information content of your overview diagrams.
Status di splay
The status display graphically visualizes the information statuses Not topical, WIN CC status not OK, Bay blocking, Telecontrol blocking a nd Manually updated.
Via a context menu, you can display the current status of a selected information object in text form.
The color representation of the individual status in the graphical representation can be selected for the individual user.
Dynamizations
If a distinction must be made between synchronized and unsynchronized controlling of a switching device, you can define additional dynamizations in the switching device object. In this way, the control dialogs are extended and the control method can be chosen in runtime. Some SIPROTEC 4 bay devices support synchronized s witching.
If the switching device objects are only used in monitoring direction (missing entry of the control variables), no control dialog is output.
Two-step control ling
The switching devices are controlled in two steps with the IndustrialX Controls. The switching direction is selected in the first step, whereas the command output is initiated in the second step.
If a subdevice supports the Select before Operate function, it can be combined with the two-step method.
EnableSwitching
Depending on other tabs (variables), control dialogs can be prevented in runtime. As an example, this feature is used if the switching authority changes between several operator terminals of a SICAM WinCC Client/ Server configuration.
PermissionLevel
In the WinCC properties dialog, you can specify the user authorizations to determine which operator actions or parameterization tasks may be performed by a certain operator.
LabelButtonOn
With this parameter in the WinCC properties dialog, you can specify object-specific texts for runtime dialogs e. g. Step up/Step down for the transformer control.
Language adaptation
The default version of SICAM PAS CC provides German and English configuration and runtime dialogs.
However, all texts used in these configuration and runtime dialogs are stored in text files. For this reason, they can be translated conveniently to other languages.
SICAM PAS CC alarm logg ing - message list s
In the SICAM PAS CC message lists, the incoming messages are logged with the absolute time stamps formed in the bay devices or substations.
The time stamp and the message state are completed by additional information. Examples of additional information: Cause, event source, status information, protection times, etc. Besides the values IN/OFF and RAISED/CLEAR, the value display also comprises fault positions (double-point indications) and bit pattern indications.
Value texts can be parameterized for the individual message, such as Step up/down. You can create up to eight different value text groups.
Command output indications are logged in addition to process indications. In the alarm list, you can select which indication status is to be ackno wledged.
• RAISED state • CLEAR state
• RAISED and CLEAR state.
RAISED indications remain in the alarm list until the corresponding CLEAR indication and the acknowledgement which might be required.
Status of the devices SICAM PAS CC visualizes the status of the device connections to the SICAM PAS Station Unit. If the connection is lost, the color of the switching device objects and measured-value objects in the diagram changes.
In addition to this, the device status can be logged in the message lists. SICAM Valpro
SICAM Valpro is an optional component for the processing, display and printing of archived measured and metered values. It is based on the SICAM PAS CC archive system (SIMATIC WinCC tag logging).
SICAM Valpro displays archived values in a graphical or tabular representation. The following values are evaluated:
• Original values
• Maximum and minimum values in different time intervals, e. g. 15
minutes or hourly values
• Power factors
• Sum/difference values of metered values in different time intervals.
Groups can be defined for the representation and measured values can be assigned to the groups.
The diagram representation can be defined freely with regard to many properties, such as the curve type or the background.
Curve properties can be defined specifically for an individual curve.
Measured-value curves are represented analogous to the fault record evaluation. The tabular representation of the archived values can be added to the graphical
representation or positioned independently. The cursor po sition and the first visible table row correlate.
Graphical representations and tables can be output on a printer.
Tables with archive data can be exported in the CSV format, whereas text reports can be exported in the text format. In this way, they are available for further processing in other programs (such as Excel).
SICAM Valpro can be used on the SIMATIC WinCC Server or clients. As an alternative, it can also be executed independently of SIMATIC WinCC. For the offline evaluation, you require group files which you have created with SICAM Valpro in the SIMATIC WinCC environment.
SICAM Recpro
SICAM Recpro is an optional extension block for the management, archiving and evaluation of fault records. It can also be used independently of SICAM PAS CC.
For protection devices connected to a SICAM PAS Station Unit via the IEC 60 870-5-103, PROFIBUS FMS or IEC 61850 protocols, the fault records created in these devices are transmitted automatically. These fault records are archived automatically in communication- specific directories on the fullserver or DIP.
The fault records transmitted can be evaluated using SICAM Recpro. SICAM Recpro consists of the following components:
• SICAM Recpro Explorer
for the management and evaluation of fault record archives in combination with an evaluation program.
• SICAM Recpro Collector
for the generation and management of a central fault record archive
• ComtradeView
for the visualization of fault records
SICAM Recpro provides additional, complementary features such as
• Adaptation of the channel texts in the fault records via device-specific channel text
files, also from third-party devices
• Export functions
Export of fault records in the Comtrade format
Export of an overview of the fault record archive contents to a text file
• Import of external fault records in the Comtrade format • Evaluation function
Zone diagram based on a fault value file in the RIO format.
9.7.2. Displaying
The spatial and functional correlations of your system components can be represented in more or less detailed diagrams.
Graphical representations of individual system components or devices can be constructed in addition to overview and system diagrams.
In addition to this, your process information can be logged in an event list.
SICAM Valpro can also evaluate archived measured and metered value via graphical or tabular representations.
The graphical fault record evaluation with SICAM Recpro completes the visualization options of your system data.
