2. GENERAL SYSTEM DESCRIPTION
The SICAM PAS system is an op en, modularly-designed numerical system for energy automation. The specific functions of a power automation system are combined with those of a programmable logic controller system and include the communication possibilities of today’s IT-world.
SICAM PAS has been designed specifically for the requirements of energy & power automation systems and is scalable due to its distributed architecture. The SICAM PAS power automation system provides a system solution for an efficient execution of all tasks required in a substation. SICAM PAS can be integrated into the existing communication structure of the substation, using standardized communication standards. SICAM PAS can also be used as a communication gateway.
The full graphical process visualisation system SICAM PAS CC (CC: control centre) can be located directly in the substation and provides for easy control and monitoring. (See chapter 3 for a more detailed description of SICAM PAS CC).
The CFC (Continuous Function Chart), a user-friendly graphical configuration tool for automation purposes is an option, included in the option is the specifically developed substation automation CFC function blocks.
New devices can be integrated into the system and can be intuitively configured (via SICAM PAS UI). Especially using the possibility to adapt the configuration and the on-line settings (when the configuration is done on the SICAM PAS running the same hardware), without generation and loading, this makes the parameterisation and testing quicker and easier.
For diagnostic purposes SICAM PAS has dedicated tools aboard.
With using IT technology and with its integrated tools for test and diagnostics SICAM PAS is ready for the future, which a also secures the investment.
The SICAM PAS power automation system provides innovative solutions for most diverse task definitions resulting from the use of distributed information systems in different locations. It is suitable for use both in interconnected and distributed switchgears of electric utilities and in the manufacturing industry.
SICAM PAS has been designed as a modular, open system which complies with all widely used communication standards. In addition to this, it supports you in the implementation of project-specific automation tasks in the field of substation automation and power automation.
The SICAM PAS CC control and display system provides numerous options to realize your system management concept via individually designed user interfaces and operator actions.
The consistent use of Windows technologies, convenient user interfaces and the operating logic of the system components ensure that newcomers become familiar with SICAM PAS within a short time.
3. SICAM PAS SYSTEM ARCHITECTURE
Possible topologies of the SICAM PAS system are shown below. These do not necessarily fit together with the architecture on which this offer is based.
Please see part C for the valid SICAM PAS architecture, as well as part B for the scope of delivery and service for this offer.
3.1.
SICAM PAS a system with distributed architecture
The SICAM PAS system consists of one Station Unit called “Full Server” (In a SICAM PAS hot-hot redundant system there are 2 “Full Server”) When wanting to increase the performance, numbers of connections ,system availability and topological reasons the SICAM PAS system can be
extended with additional Station Units named “Device Interface Processor DIP“.
• SICAM PAS is suited for the operation in a substation with one SICAM PAS Station Unit • Can also work in co-operation with other SICAM PAS Station Units in a distributed system.
The various SICAM PAS Station Units are in this case exchange information via a powerful Ethernet- LAN.
A powerful data distribution system for real time data enables the SICAM PAS system to allocate tasks to various SICAM PAS Station Units. These Station Units together form one SICAM PAS system and thus have a higher performance, system availability and more connections
Picture 1- SICAM PAS System consi sting o f one Station Unit „ Full Server“
Picture 2- Distrib uted SICAM PAS system (one Station Unit „ Full Server“ and up to 6 Station Units „ Device Interface Processor“)
3.2. Hot-Hot (Control Master/ Monitoring Only) redundancy of a SICAM
PAS system
The availability of the SICAM PAS power automation system can be further enhanced in doubling the SICAM PAS Station Unit „Full Server“.
The HMI server can also be built redundantly, as shown below and can serve several HMI clients.
Picture 3- redundant SICAM system (2 Station Units „ Full Server“ and redundant HMI server with 3 HMI clients)
The architecture consists of the 2 SICAM PAS systems in a hot-hot configuration. Both systems are acquiring data independently from each from the connected IED’s and/or satellite RTU’s. This hot-hot redundancy can be used only together with IED’s and satellite RTU’s which support dual/multiple master protocols (i.e. Profibus FMS, IEC 60870-5-101) or client <-> server protocols as a server which can be accessed from dual / multiple clients (IEC61850) Both SICAM PAS “Full Servers” data bases are automatically yet independently updated from the field connected IED’s and satellite RTU’S (monitoring direction) No information exchange between the HOT-HOT SICAM PAS station units is required when no internal commands are generated (e.g. derivation
from an indication) and there are 2 independent telecontrol connections to the control centre (which selects the active channel).
In case internal commands are generated or only one telecontrol interface is available, an exchange of a status (“Control Master” / “Monitoring only”) between both SICAM PAS Station Units is a necessity to ensure that only one source is enabled to send commands and to switch the telecontrol interface to the Station Unit with the status “Control Master”.
Possible locations for controls are:
• Local HMI SICAM PAS CC
• Remote control from a control centre
• Internally generated command (derivation, automatic sequence,…)
The following mechanisms are providing the necessary functionality of a single command source:
• SICAM PAS CC => Software redundancy function of WinCC • Remote Command => task of the connected control centre
=> Switching the telecontrol interface, when one is only available
• Internally generated command => CFC logic
The switching between of the status (“Control Master” / “monitoring only”) of the 2 „Full Server“ can be done via:
• Internal supervision function
o Done with CFC logic
o Exchange of status via OPC mechanisms
• Operator from SICAM PAS CC HMI place
Optional additional information can be generated and exchanged Verification of the status of the communication drivers to IED’s and satellite RTU’S connected to both Station Units
=> Switch over criterion: Station Unit 1 drivers not o.k. / Station Unit 2: drivers o.k.
• Information to the control centre which Station Unit is the “Control Master” • Life signal from both Station Units to the control centre

7. COMMUNICATION INTERFACES
The communication with the control centres, satellite RTU’s and IED’s are processed using the following interfaces:
• LAN - Ethernet TCP/IP interface(s) of Station Unit(s) „Full Server / DIP“ • Communication with IED’s IEC 61850 client
• Communication with control centres using IEC 60870-5-104 • Communication between Station Units „Full Server“ and „DIP“
• Communication between SICAM PAS Station Unit(s) and SICAM PAS CC HMI • Communication with the open interface using OPC client-server mechanisms • Connection of a COM-Expander via TCP/IP
• Serial COM-interfaces of the Station Unit(s) „Full Server / DIP“
• Communication with control centres using IEC 60870-5-101 slave or DNP V3.00 (level 2) • Communication with satellite RTU’s using IEC 60870-5-101 master or DNP V3.00 (level 2) • Communication with IED’s using IEC 60870-5-103

• Communication with IED’s via Profibus DP
• The SICAM PAS Station Unit(s) is/are equipped always with: • 1 x LAN – Ethernet TCP/IP interface
• 2 serial COM interfaces
Up to 4 CPCI modules (depending on the ordered type) can be used additionally in a SICAM PAS Station Unit. One of these CPCI slots is used (by default) to insert a GPS-time synchronization module. Thus when using GPS only 3 slots can be u sed for extension of the communication interfaces of the SICAM PAS Station Unit(s):
• Additional serial interfaces:
o Using PCI COM-Expander (e.g. Rocket Port) to extend the number of serial
interfaces up to 32
o Using Rocket Port serial Hub via the Ethernet LAN.

In the IEC 61850 Standardization papers special requirements are defined regardingenvironmental conditions Switches und Hubs, these requirements are considered in the selection of used Switches / Hubs for connection of IEC61850 IED’s
For the connection of IED’s via a fibre optic network, using fibre optic star-couplers, OLM’s (optical link module), OSM’s (optical switch module) or Ethernet switches/Hubs with fibre optic interfaces can be used, depending on the used transmission protocol.
7.1. Communication via telecontrol protocols
The communication up to 5 control centres per SICAM PAS system with different protocols can be used. The communication interfaces are independent of each other and can b e located, in a „Full Server“ and also in a „DIP“.
The following protocols are implemented for communication to a control centre:
• IEC 60870-5-104 (TCP/IP),
• IEC 60870-5-101 (balanced and unbalanced), • DNP V3.00 (level 2)
Our scope of supply ends with the physical telecontrol interface of the SICAM PAS Station Unit(s). Especially in case of the LAN/WAN based telecontrol protocol IEC60870-5-104 where the
substation is connected via a router (not in our scope) it is necessary that the owner of the
substation implements all aspects of security (like firewall …) in the used router in order to protect the substation against unauthorized access.
Satellite RTU’s can be connected to the SICAM PAS system via the telecontrol protocols IEC 60870-5-101 and/or DNP V3.00 (level 2).
The transmission rate of the implemented protocols can be at maximum:
• IEC 60870-5-104 (Slave) 10/100 MBit/s
• IEC 60870-5-101 (Slave) up to 38,4 kBit/s (balanced and unbalanced mode) • DNP V3.00 Level 2 (Slave) up to 38,4 kBit/s
• IEC 60870-5-101 (Master) up to 38,4 kBit/s (balanced and unbalanced mode) • DNP V3.00 Level 2 (Master) up to 38,4 kBit/s
The implemented functions of these protocols and the rules for exchanging the data between the SICAM PAS system and the control centre are described in the attached protocol description / interoperability list.
7.2. Communication with IED’s and satellite RTU’s
The maximum number of IED’s and/or satellite RTU’s which can be connected to a SICAM PAS system is 150, independent o f the used communication protocol (IEC61850, IEC 60870-5-101, IEC 60870-5-103, DNP V3.00 (level 2), Profibus FMS / DP or Modbus-RTU).
The following protocol options (available per order code) for communication to IED’s and satellite RTU’s are available for the SICAM PAS system:
IEC 61850 IEC 61850 is the international standardized communication protocol in a substation for connecting IED’s and devices within a substation using
Ethernet MMS. IEC 61850 also supports a direct data exchange (broadcast, multicast) between IED’s and therefore allows for example system
interlocking without a central unit.
Profibus FMS Most SIPROTEC 4 bay control and protection relays can be connected to the SICAM PAS Station Unit using Profibus FMS. Within Profibus FMS many features which a re later found in the IEC61850 can already be used.
IEC 60870-5-103 Many of suppliers of protection relays, bay controller, and other IED’s support this protocol and can be connected to the SICAM PAS. IEC 60870-5-101 (Master) the international standardized protocol IEC 60870-5-101 is
used for the connection of satellite RTU’s.
‚balanced‘ and ‚unbalanced‘ modes are supported. For the connection of satellite RTU’s automatic dial-up communication is also supported.
The establishment of the connection to the satellite RTU can be done cyclically and driven by event (e.g. to send a command). In monitoring direction the establishment of the connection can also be done cyclically and driven by events.
Analogue and ISDM modems can be used; it is also possible to use a GSM modem in the substation. For the communication to the satellite RTU’s Backup modems can also be used.
" other satellite RTU’s can therefore be connected when the “standard modem” is busy.
PROFIBUS DP PROFIBUS DP is a powerful field bus protocol using the Token-assingprocedure.
This protocol is mainly used in the process automation area and also in automation systems for energy- and gas- substations.
For simple applications, where functions like time synchronization and transmission of fault recording is not required, SIPROTEC 4
relays can be connected to the SICAM PAS Station Unit using Profibus DP.
Additionally connecting IED’s with DNP V3.00 (level 2) and Modbus RTU protocol is possible. Examples for the connection of IED’s
Depending on the implemented functions and the technical specifications of the hardware and the interfaces, the following combinations may be implemented:
IEC 61850
• SIPROTEC 4 protection relay • SIPROTEC 4 Bay Processing Unit
• Protection devices of third party manufacturers
IEC 60870-5-103
• SIPROTEC 3 protection relays • SIPROTEC 4 IED’s
• Protection devices of third party manufacturers • Bay coupling unit 6MB525
• Measuring transformer SIMEAS T
• Transformer controller manufactured by Companies: Eberle or Reinhausen
Profibus FMS
• SIPROTEC 4 protection relay • SIPROTEC 4 Bay Processing Unit
DNP V3.00 (level 2)
• IED’s of third party manufacturers
Profibus DP
• DP standard slaves (e.g. ET200) • Power meter SIMEAS P
Modbus
• IED’s of third party manufacturers (e.g. Measuring Centers) • PLC units
7.3. Communication using the „open interface OPC“
With the OPC Server SICAM PAS process variables can be read and written from OPC clients which arelocated either in the same system or connected via TCP/IP to the SICAM PAS system. Using these OPC mechanisms it is for example possible to connect a third party HMI.
The OPC Server is part of the SICAM PAS basic package.
The OPC Client can read and write data from other OPC-Servers. An application example is the data exchange between the SICAM PAS Station Unit and the SIMATIC automation systems.
7.4. Communication with the HMI system
The process visualization and control System SICAM PAS CC is connected via LAN connection (Industrial Ethernet TCP/IP) to the SICAM PAS Station Unit(s).
The SICAM PAS CC visualization and control system can be configured as: • Single User System (1 SICAM PAS CC to control 1 SICAM PAS system) • Multi User System (1 SICAM PAS CC to control several SICAM PAS systems) • Multi User System using client/server architecture
The SICAM PAS CC Server can be redundant Please see chapter 3 for more detailed description of the SICAM PAS CC visualization and control system and the system requirements.
8. SYSTEM SAFETY
Reliability and safety requirements as required in a substation automation system are fulfilled to a high degree by the SICAM PAS system. Electromagnetic compatibility of SICAM PAS electronic components is also given particular attention.
SICAM PAS promptly signals faults because it has continuous running safety check running in the background. This ensures that the operation /maintenance personnel can locate the faulty system components more quickly.
• Interruption of power supply
The SICAM PAS system automatically reboots after an interruption of the supply voltage. All the parameters are securely stored in the real-time data base and all applications are started as “services” automatically in the same state as before the interruption. The SICAM PAS system is designed to be maintenance free, i.e. no buffer ba tteries are required and there is fan -free operation.
• Communication
Faults in data transmission caused by electromagnetic influences, earth potential differences, ageing of components or other disturbances or noise sources on the transmission channels, are reliably detected. The safety procedures of the protocols detect:
• Bit and message errors, • Information loss or repetition, • Faulty information items,
• Separation or corruption of contiguous information items. • Priority-controlled message preparation
Messages activated by events are priority-controlled and rapidly made available to the system. The following lists are provided:
• Basic cycle list • Periodic list • Interrogation lists • Time-controlled lists • Spontaneous lists, • with/without time delay
• prompt memory/message memory • Organizational list
• A telecontrol fault group indication can be parameterised from individual information items
and transmitted as a group indication to the control centre, logged or used for signalling at the cubicle.
Using the graphical automation tool CFC single faults can be easily and comfortably grouped in a user friendly way, using the structured text function of the automation tool of SICAM PAS.
Our scope of supply ends with the physical telecontrol interface of the SICAM PAS Station Unit(s). The connection to a public net using Web-browser or WAN connections via router is within the responsibility of the substation owner.
Especially in case of the LAN/WAN based telecontrol protocol IEC60870-5-104 where the substation is connected via a router (not in our scope), it is necessary that the owner of the substation implements all aspects of security (like firewall …) in the used router in order to protect the substation of unauthorized access. At the latest after commissioning or transfer of the equipment for operation Siemens will not be able to ensure that all security relevant patches can be installed, therefore Siemens must reject the responsibility for the protection against unauthorised access.
9. OVERVIEW OF FUNCTIONS
9.1. Overview
SICAM PAS has been designed as a modular system with open communication interfaces. In this way, it meets the requirements of stateof-the-art power management systems and of the power supply equipment of industrial manufacturing plants.
This modular structure also allows to flexibly combine the individual system functions. Only those components required on a certain computer must be installed and authorized there. The following sections provide an overview of the individual system components and their tasks. These include:
SICAM PAS UI - Configuration Automation Functions
Feature Enabler
SICAM PAS UI - Operation SICAM PAS Value Viewer SICAM PAS CC
SICAM Recpro SICAM Valpro
Complementary to the above-mentioned components, following Chapters describes substation control functions such as:
Switching authority Bay blocking
Telecontrol blocking Time synchronization Fault recording
9.2. SICAM PAS UI - Configuration
The SICAM PAS UI - Configuration system component is used for
• the configuration and parameterization of your system as well as for • the exchange of configuration data.
9.2.1. Configuration and Parameterization
The clearly structured configuration interface provides you a comprehensive overview of your system parameters.
Import and export functions allow the exchange of configuration data. This reduces the expenditure and error sensitivity during the configuration and parameterization of a system. The elements of the user interface can be arranged according to the requirements of the individual user. You can specify that continuously required table columns are always shown in the corresponding view, whereas non-required columns are hidden. The settings are maintained also after a restart of the program.
Sorting and filter options provide for increased transparency and convenient parameterization.
System-specific automation functions are graphically configured. To do so, you use both default logic functions and specific power automation function blocks.
Your parameter entries are immediately checked for plausibility. Tooltips provide information on the permissible values or on the value range. In addition to this, the user is supported by a context-sensitive online help.
It is not necessary to explicitly generate the configured and parameterized data for the runtime environment.
SICAM PAS UI - Configuration structures the parameters in the individual views:
• Configuration • Mapping • Topology and • Templates
Configuration In this view, you specify the components of which your SICAM PAS system consists. These include:
• Applications
IED protocols, control center connection, HMI (SICAM PAS CC), automation (CFC) and OPC.
• Interfaces
Serial interfaces, Ethernet, PROFIBUS
• Devices / control center
Bay controllers and protection devices, transformer controllers, distributed I/Os or depending on the protocol of a control center.
The configured components are represented in a tree structure, whereas the parameters of the selected components are displayed in the data pane.
Picture 4- SICAM PAS Configuration
Mapping In this view, you select which information is to be used in the previously inserted applications of your system.
For the interface to higher-level control centers, you also specify telecontrol addresses, the list assignment and protocol type-specific parameters.
Picture 5- SICAM PAS Mapping of the information of a device
Topology The configuration view of your system is orientated towards communication. In contrast to this, the topological view allows to create a system view which is structured according to the requirements of an individual project. Levels of information such as substation, voltage level, bay and any other
structurization levels are created in this context.
On these levels, you can simply distribute the configured and parameterized information via Drag & Drop.
Picture 6- SICAM PAS topology, example of information of the SICAM PAS substation
Templates In the template view, you can define device- and project-specific device descriptions and templates for normalizations of information.
You can assign project-specific information names and addresses. Moreover, you can specify command execution times, the assignment of commands and command feedbacks or the type of information.
Picture 7- SICAM PAS templates, example of a PROFIBUS FMS device
9.2.2. Exchanging Configuration Data
If devices which have already been parameterized completely are integrated in
interconnected systems, these configuration data can be imported in SICAM PAS. As an example, you can integrate substations parameterized with SICAM plusTOOLS or the project-specific information volume of the bay and protection devices into SICAM PAS.
If modifications to the information volume result, you can conveniously update already imported project data.
Importing configuration data
You can import the configuration data of bay and protection devices in the DBF, XML or SCD format, whereas configuration data of substations are imported in the XML format.
For IEC 61850, all devices included in an SCD file are imported and created automatically within the framework of the SCD file import.
Export of configuration data
Control center Configuration data created via SICAM PAS for the
connection of your station to higher-level control centers via IEC 60870-5-101 can be exported in the XML format and then imported by the control system.
SICAM PAS CC Configuration data required for the process visualization via SICAM PAS CC are exported in the PXD format. Afterwards, these data are imported by the SICAM PAS Wizard and used for the generation of the control and display interface of your SICAM PAS system.
Exchange of configuration data via OPC
If your SICAM PAS system works as a n OPC Client, you can apply data of the corresponding OPC Server. In this context, the OPC Browser displays in a comprehensive manner which information is available and which information is already used.
This is a convenient method to extend or reduce a n already performed data selection.
9.3. Automation Functions
The SICAM PAS automation blocks provide a comprehensive tool allowing individual solutions of operational automation tasks.
Automation functions are formulated via CFC or Structured Text (ST). CFC allows the graphical connection of function blocks. In addition to usual link blocks such as AND, OR, NOR, etc., you can use a comprehensive library of system-tested power
automation function blocks.
• Command processing o Command derivation o Interlock tasks • Message processing o Message derivation o Message filtering
o Inversion and conversion of messages o Group indication formation
o Transformer tap and bit pattern comparisons
• Measured- and metered-value calculation
o Non-linear characteristic o Limit value monitoring o Slave pointer
o Mean value formation
o Arithmetic and comparison blocks
• Switching sequences
Simple configuration rules simplify the definition and interpretation of function charts; the chart-to-chart technology provides for a comprehensive overview.
For the configuration via SICAM PAS UI - Configuration, you simply selet information required for your automation tasks. Already there, you can group information which is used collectively (if required).
Picture 8- SICAM PAS, example of a command interlock
9.4. The Feature Enabler
Use the Feature Enabler to enable the applications which you require in your project or on the corresponding computer.
In this context, applications are:
• the different protocols • the configuration tool
• the CFC automation function • OPC connections
Picture 9- Feature Enabler
9.5. SICAM PAS UI - Operation
SICAM PAS UI - Operation provides a quick overview of the runtime status of your system. The configuration is displayed in the tree structure and the representation via different colors provides a quick overview of the status of interfaces, devices or other applications.
The component selected in the tree structure can be enabled or disabled in the data pane.
Picture 11- SICAM PAS UI - Operation
9.6. The SICAM PAS Value Viewer
The SICAM PAS Value Viewer is an important tool for the project phases of configuration, testing, commissioning and operation.
Without any additional configuration expenditure, it allows the visualization of process and system information and informs you about the current status of your system. In addition to the check in monitoring direction, tests can also be performed in control direction via command outputs.
Picture 12- SICAM PAS Value Viewer
9.7. HMI
In the SICAM PAS system, SICAM PAS CC performs the control and display functions of the process information of your system.
In this way, functional and spatial contexts of your system components are represented conveniently in overview and system diagrams.
The logging of status changes of your process information and operator actions in the correct time sequence is performed via message lists such as the alarm and event list.
You can intervene into the process and control it from system diagrams.
System data such as messages and measured values can be logged and saved in freely definable archives.
The assignment of specific authorizations, the possibility to use bay and telecontrol blockings, different switching modes and the consideration of switching authorities complete the control functions. For more information on these functions.
SICAM PAS CC consists of the SIMATIC WinCC process visualization system and the SICAM PAS CC components.
Picture 13- SICAM PAS CC Components
SIMATIC WinCC SIMATIC WinCC provides standard function modules for the graphical display, for messaging, archiving and logging of
information. With its powerful process interface, the fast diagram update and the safe data archiving, it ensures high availability of your system data.
9.7.1. SICAM PAS CC Components
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.
Picture 17- Representation of a SIPROTEC bay device, example
9.7.3. Controlling
Depending on the parameterization of your system, you can perform control interventions of the process via detailed diagrams.
SICAM PAS CC provides different control modes:
• Switching with enabling
• Select before Operate with enable • Synchronized switching
The example below illustrates the switching of a circuit breaker from OFF to ON with enabling.
• Select the circuit breaker. Next, select Switching from the context menu.
The switching dialog parameterized for this circuit breaker (information object) is now displayed.
Picture 18- Introducing the switching operation
• Click the ON button.
The enabling can now be performed in the next dialog window.
Picture 19- Switching operation - enable
Picture 20- Switching operation completed
The switching operation is executed. The circuit breaker icon changes to the ON operating state.
The switching operation and the command feedback are logged in the e vent list.
9.7.4. Substation Control Functions
SICAM PAS provides a series of functions tailored to the requirements of substation control tasks. These include:
• Switching authority • Bay blocking • Telecontrol blocking • Time synchronization • Fault recording
9.7.4.1. Switching Authority
In distributed systems, the switching authority defines which layer has the switching
authority. The bay control layer, the station control layer or the control center layer can have the switching authority.
Besides local/remote switching by means of the key switches of the bay devices, a distinction between local and remote control can be made on the station control layer.
The switching authority can be defined for the specific channel, i. e. one telecontrol channel has the switching authority, whereas the others and the local control have no authority.
9.7.4.2. Bay Blocking
To perform maintenance tasks on a feeder, it might be useful to interrupt the data exchange in control and monitoring direction with the bay devices concerned.
The bay blocking can be enabled or disabled for a specific device.
If the bay blocking is set, value changes of the process information and the status information are not transmitted.
The bay blocking is visualized by the graphical representation variants of the switching objects.
Setting and clearing of the bay blocking is logged in the event list of the SICAM PAS CC HMI.
In addition to this, you can specify during the parameterization whether the information affected by the bay blocking are a lso marked individually as Not topical in the event list.
9.7.4.3. Telecontrol Blocking
To perform maintenance tasks in a station, it might be useful to interrupt the communication with higher-level control centers in the control and monitoring direction.
The telecontrol blocking can be enabled or disabled for a specific channel.
If a telecontrol blocking is set, the local control has the full volume of information available. Setting and clearing of the telecontrol blocking is logged in the event list of the SICAM PAS CC control and display system.
9.7.4.4. Time Synchronization
If your SICAM PAS Station Unit is to take over the time synchronization of bay devices, substations and SICAM PAS CC, this can be performed via a DCF 77 or GPS time signal receiver manufactured by the Hopf company. The SICAM PAS Station Unit itself can also be synchronized via this time signal.
9.7.4.5. Ethernet station bus
In the case of system configurations with an Ethernet station bus (IEC 61850), a separate time master can be used on the Ethernet which synchronizes all connected devices, the SNTP clients, as an SNTP server (Simple Network Time Protocol).
In this case, the SICAM PAS Station Unit also acts as the SNTP client with regard to the time synchronization. Nevertheless, it performs the synchronization of the devices connected to the SICAM PAS Station Unit via other protocols.
9.7.4.6. Fault Recording
For protection devices connected to a SICAM PAS Station Unit via the PROFIBUS FMS, IEC 61850 or IEC 60870-5-103 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
SIGRA 4 can be used for a comprehensive and sophisticated fault record analysis. This analysis tool calculates further tags and graphically represents the fault records in different views.
