OpenPCS 7
Function Manual, 05/2012, A5E02780178-02 9
Depending on the system configuration, the OpenPCS 7 station can provide data from various
OS servers and from the central archive server. The OpenPCS 7 station hides the distribution
of the data in terms of:
● Time period (OS1, OS2, …, CAS / Process Historian)
● Location (OS1, OS2, …, CAS / Process Historian) and
● Redundancy (OS1 master, OS1 standby …)
OpenPCS 7 replaces @PCS 7previously available in the context of SIMATIC PCS 7 and is,
at the same time, the equivalent of the Connectivity Station and the Connectivity Pack of the
WinCC SCADA system. Direct access to SIMATIC BATCH and SIMATIC Route Control data
is not possible with OpenPCS 7.
Basics
2.2 Microsoft basics
Layout
The OpenPCS 7 station can be operated in various configurations:
● OpenPCS 7 station without OS client, based on a SIMATIC PCS 7 Industrial Workstation
in the client version. This is the recommended preferred configuration.
● OpenPCS 7 station on an OS client.
● OpenPCS 7 station on a central archive server (CAS)
● OpenPCS 7 station on an OS single station.
● OpenPCS 7 station on the OS server.
Note
The hardware and software requirements of the PC station on which OpenPCS 7 is to be
installed must be met.
2.2 Microsoft basics
Microsoft basics
The basis of OPC is provided by several Microsoft technologies. These technologies are
explained in the following section.
OPC
OPC stands for "OLE for Process Control".
OPC is a standardized, vendor-independent software interface that allows data to be
exchanged between hardware and software. One system can provide another system with
process data via OPC .
OLE
OLE means "Object Linking and Embedding", the technology for embedding objects in
documents.
COM
COM means "Component Object Model" and is necessary for the use of OPC.
COM is a central component of Windows operating systems and controls the interaction
between multiple software components. By using COM , the OPCserver effectively becomes
part of the Windows operating system and is therefore not dependent on file names, storage
locations and versions.
COM defines a standard that allows objects to be defined as self-contained units in Windows
and to access these units beyond the limits of a process.
OpenPCS 7
10 Function Manual, 05/2012, A5E02780178-02
DCOM
Object
Events
Basics
2.3 OPC Foundation
COMobjects can be understood as extensions of the operating system. They are not
dependent on programming languages and are available in principle to all applications.
The data and code of the object are not directly accessible to the user of the COMobject.
DCOM is the acronym for "Distributed Component Object Model". It is based on COM
technology and provides the additional option of communicating over a network.
Objects are defined by properties and methods that can be used on objects.
An event is used to control program flow. Program execution is not linear, instead special event
handling routines are executed whenever a specific event occurs.
In terms of OpenPCS 7 and the OPC standard, Events mean messages / operation messages
of the PCS 7-system.
DLL
It is possible to use DLLs with Microsoft Visual Basic (VB) and Microsoft Visual Basic for
Applications (VBA). DLL stands for Dynamic Link Library. A DLL is a dynamic link library. Users
can link the functionalities of a DLL into their own applications. If you want to program an
OPCclient with VB, make sure that the relevant automation interface DLL is selected in the
VB Editor in "Project > References".
Collection
Collections are objects that support count and item properties. A collection consists of a certain
number of items. An item can be collection-specific, any data structure, or an object. The count
property specifies the number of items in a collection. In Microsoft Visual Basic, each item in
a collection can be identified using loops.
2.3 OPC Foundation
OPC Foundation
The aim of the OPC Foundation is to ensure compatibility between different subsystems in
automation and process control engineering. Compatibility is achieved by creating and
maintaining open specifications for the standardization of communication between subsystems
of different manufacturers. This allows process data, alarms and messages as well as archived
process data to be exchanged between subsystems regardless of their manufacturer.

Basics
2.4 Components of OpenPCS 7
The OPC Foundation has more than 300 members worldwide. These include the most
important manufacturers of control systems, process instrumentation and process control
systems worldwide. SIEMENS is a member of the OPC Foundation.
The declared goal of the OPC Foundation is vertical integration of information from the field
level through to the enterprise level. Using the OPC standard, this integration is possible
regardless of the system and manufacturer.
The most important standards of the OPC Foundation for OpenPCS 7
● Data Access Custom Interface Standard
● Data Access Automation Interface Standard
● Historical Data Access Specification Standard
● Historical Data Access Automation Interface Standard
● Alarms and Events Custom Interface Standard
● Alarm & Events Automation Interface Standard
2.4 Components of OpenPCS 7
Overview
OpenPCS 7 provides the following components:
● OPC DA (Data Access server)
● OPC HDA (Historical Data Access server)
● OPC A&E (Alarms & Events server)
● OPC "H" A&E (Historical Alarms & Events server)
● OLE DB
In the following graphic, you can see all the OPC components that will run on the OpenPCS
7 station. The figure also shows the PCS 7environment. OLE DB starts a direct database query

2.4 Components of OpenPCS 7
OPC DA (Data Access server)
For read and write access to process values according to the OPC specification OPC DA
V1.00, V2.05a, V3.00.
As an OPC DA server, the OpenPCS 7 station provides other applications with current data
from the OS data management. The OPC DA client can register for current changes or write
values.
OPC HDA (Historical Data Access server)
For read access to archived process values according to the OPC Specification OPC HDA
V1.20.
As an OPC HDA server, the OpenPCS 7 station provides other applications with historical data
from the OS archive system. The OPC client - for example a reporting tool - can specifically
request the data required by specifying the start and end of a period. Various aggregate
functions, such as variance, mean value, or integral, allow preprocessing by the OPC HDA
server and contribute to a reduction in the communication load.
OPC A&E (Alarms & Events server)
For read access to messages, alarms and events according to the OPC Specification OPC
A&E V1.10.
As an OPC A&E server, the OpenPCS 7 station forwards OS messages with all the associated
process values to the subscribers at the production and enterprise management level. OS

messages can also be acknowledged via this server. Filter mechanisms and subscriptions
ensure that only selected, changed data is transmitted.
OPC "H" A&E (Historical Alarms & Events server)
For read access to archived alarms and messages.
Thanks to an expansion of the OPC standard interface by Siemens, the OpenPCS 7 station
is also able to transfer historical alarms and messages from the archive to the subscribers at
production and enterprise management levels.
OLE-DB
The WinCC OLE DB provider allows standardized and direct access to the archive data in the
Microsoft SQL server database on the OS server.
This setup permits access to all OS archive data, along with the associated process values,
message texts, and user texts.
2.5 OLE DB interface
OLE DB
The WinCC OLE DB Provider allows access to the process value and message archives.
Compressed process value archives are made available uncompressed. OLE DB is used to
read the PCS 7 OS or archive server database remotely.
OLE DB is an open standard for fast access to different databases. The connection between
the OLE DB level and the database is established by a database provider.
The WinCC OLE DB provider, which is integrated in the OpenPCS 7 station, enables
transparent access to archived process data of the following PCS 7 stations:
● PCS 7OS server
● Central archive server
2.6 COM / DCOM components of OpenPCS 7
COM / DCOM components used by OpenPCS 7
● OPC client runs on the OpenPCS 7 station
If the OPC client and OPC server process run on one computer, the OPC client accesses the
local OPC server object using an "in-process server" component via LRPC and a stub object.

2.6 COM / DCOM components of OpenPCS 7
● OPC client runs on a separate computer
If the OPC client and the OPC server process run on separate computers, the OPC client
accesses a local and a remote proxy object. These objects communicate via RPC and a stub
object, with the OPC server object on a different computer.
Remote Procedure Call (RPC) is a technique used for communication between different
processes. The processes typically run on different computers.

On a PC with the Microsoft XP operating system, Microsoft permits 10 connections between
PCs. COM access between an OPC client and the OpenPCS 7 station does not count as a
connection in this sense.
3.4 Licensing the OS-internal OPC server
Licensing
The PCS 7 OS provides the following internal OPC servers on an OS server or an OS single
station:
● SOPCSRVRWinCC.exe for OPC DA
● SOPCAESRVRWinCC.exe for OPC A&E
● SOPCHDASRVRWinCC.exe for OPC HDA

Installation and licensing
3.4 Licensing the OS-internal OPC server
These internal OPC servers can be used with OpenPCS 7-licenses. This is only possible if the
"OpenPCS 7 station / OS" or "OpenPCS 7 station" license is available on the OS station.
Note
If the internal OPC servers of an OS station are used, this represents additional load in terms
of the OS station's performance.

4.1 Configuring an OpenPCS 7 station
Introduction
The OpenPCS 7 station is configured as a SIMATIC PC station in the SIMATIC Manager. It
includes the "SPOSA application" object. SPOSA is the acronym for Single Point Of System
Access. The OPC client application can also be executed on the OpenPCS 7 station. During
configuration, the following steps need to be taken:
● Insertion of a SIMATIC PC station
● Insert and configure the SPOSA application in the hardware configuration of the SIMATIC
PC station
If you created the multiproject with the PCS 7wizard, you will already have inserted an
OpenPCS 7 station if you selected the appropriate option. You can also insert an OpenPCS
7 station by expanding the project later with the "Expand Project" PCS 7wizard. The steps
required to create an OpenPCS 7 station manually are explained in the following section.
Requirement
4
Procedure
The PCS 7 project is open. You have created the OS servers and generated the server
packages.
1. Select the project into which you want to insert the OpenPCS 7 station, in the component
view of the SIMATIC Manager.
2. Select the menu command "Insert > Station > SIMATIC PC Station".
A new SIMATIC PC station is inserted into the selected project.
3. Select the SIMATIC PC station, select the menu command "Edit > Object Properties" and
enter the desired name for the PC station and the computer name.
4. Select the SIMATIC PC station in the component view and open the hardware configuration
by double-clicking on the "Configuration" object in the detailed view.
The SIMATIC PC station hardware configuration opens.
5. If the hardware catalog is not visible, select the menu command "View > Catalog".
6. Select the SPOSA application from "SIMATIC PC Station > HMI" in the hardware catalog
and drag it to the configuration table.
7. Save and compile the hardware configuration using the menu command "Station > Save
and Compile"
8. Expand the newly created PC station and the SPOSA application in the SIMATIC Manager.

4.2 OpenPCS 7 and OS application on a shared PC station
9. Open the object properties of the "Open_PCS7_Station(1)" object and enter the download
path to the OpenPCS 7 station in the "CPU" tab.
10.Right-click on the "Open_PCS7_Station(1)" object to open the shortcut menu and select
"Assign OS Server...".
11.Assign the PCS 7 OS server packages to the SPOSA application.
12.Open the hardware configuration of the OpenPCS 7 station and select the menu command
"Station > Save and Compile".
13.Right-click on the "Open_PCS7_Station(1)" object to open the shortcut menu and select
"CPU > Download".
4.2 OpenPCS 7 and OS application on a shared PC station
Configuration
In the hardware configuration of the PC station, you configure a "SPOSA application" and a
"WinCC application client". Likewise, you can configure a "WinCC application", "CAS
application" or "CAS application standby". You specify the path to the target system of the
OpenPCS 7-computer in the object properties of the "SPOSA application". You configure the
path to the target OS computer in the object properties of the "OS client application".
Note
In a PCS 7-version lower than V7.1, a SPOSA application and an OS client cannot be
configured on the same SIMATIC PC station. In a PCS 7-version lower than V7.1, two PC
stations with the same computer name but with different PC station names must be
configured.

4.3 Configuring an OPC client
OPC client engineering within PCS 7
OPC client engineering is not part of the PCS 7 engineering. No PC station is inserted and
configured in the SIMATIC Manager. In the SIMATIC Manager, only the OpenPCS 7 station
OPC client configuration outside PCS 7
is configured.
Note
If you want to use the SIEMENS OPC Automation Interfaces, the OPC client must be
executed either on the OpenPCS 7 station or you will have to take steps manually to ensure
that the required files exist and are registered on the OPC client. Refer to the section "
Configuring an OPC client computer".
An OPC client communicates with the OpenPCS 7 station via a network connection. We
recommend that you install a firewall between the OPC client and the OpenPCS 7 station if
the OPC client is on a non-secure network. So that communication between the OPC client
and OpenPCS 7 station works correctly, you need to configure the firewall and configure the
DCOM settings on the PC on which the OPC client is being executed. You will find the relevant
settings in the documentation of the OPC client and the firewall.
Note
PCS 7 Engineering
4.3 Configuring an OPC client
The DCOM and firewall settings for the Windows operating system are described in the
documentation "Using OPC via DCOM with Microsoft Windows XP Service Pack 2" from the
OPC Foundation.
Note
If you want to use an OPC client on a PC without an OpenPCS 7-installation, you will need
to install the OPC proxy / stub components of the OPC Foundation. You can install these
with the "OPC Core Components 3.00 Redistributable" setup of the OPC Foundation. In this
case, you should also check the installation instructions of the OPC client vendor.
