Typical field of application
Service and maintenance on the AS hardware configuration.
Steps of classic way
1. Configure of the AS in the project on the Field PG as an image 1:1 of the real
hardware.
2. Connect the Field-PG to the AS and set the corresponding PG/PC interface.
3. Download of configuration data to the AS.
4. Disconnect the Field PG from AS.
The Field-PG respectively its PG/PC interface is not part of the project, but it works only
as "loading station".
The interface has to be set individually for the selected connection type to be able to
reach the target station.

Inserting an separate station for the ES
For every AS or PC to be used in a PCS 7 project, a station configuration is to be made.
In contrast to a Field-PG, the ES is involved into the project and into the common
network of all stations. Thus, all downloads can be handled with one PG/PC interface.
Configuration of stations:
• Make an “image” 1:1 to the real existing hardware of every station in the project.
• Configuration conforming to slots:
AS hardware is structured by slots in a rack. Each slot is allocated by a hardware
component like power supply, CPU, CP…
Properties of the component in a slot include type, addresses…
Since there is no real existing slot orientation of components in a PC station, a structure
with slots similar to an AS rack is simulated by the Station Configurator.
From this follows, that the PC hardware has to be described in 2 different localizations:
• Hardware of the station, represented by the Station Configurator of the PC station
• Hardware description in the HW config of the PCS 7 project

PCS 7 System Course
Configuration of network and communication connections:
• You specify the network assignment of components capable of communication during
hardware configuration of a station in the HW Config.
• The SIMATIC Manager tool NetPro graphically displays all configured stations and
networks of a project. All bus systems and stations have their own representatives.
PG/PC Interface
The interaction of your PC Station with various bus systems for networking of
automation systems (e.g., MPI bus, Industrial Ethernet,…) requires specialized
interfaces. Each of your integrated and installed interfaces is represented by an
interface parameter assignment.
“PC internal”
"PC internal" is a centrally configurable interface, which can be loaded with project-
specific settings for all stations on the plant bus. The settings are made on the ES in the
PCS 7 multiproject and downloaded from the ES.
As soon as "PC internal" is activated, the network adapter begins working in
"configured mode", otherwise it is in "PG mode".

The central ES has to be loaded at first with all information to get the capacity for
download to all other station (AS and OS) involved in the PCS 7 project.
The configuration data are checked during the download. Both the configuration in the
PCS 7 project and the configuration in the Station Configurator have to contain the
same information as precondition for a successful download.
Status information about "download successful / unsuccessful" is displayed in the
Station Configuration Editor.
After successful download, the ES has access to the IE network, and within access to
all connected stations:
AS and PC stations (e.g. server) can be reached and loaded via ES-CP and “its

After successful downloading to ES the AS hardware configuration can be downloaded

front side of CPU give status information about "download successful / unsuccessful".
6.1.3 Extension of ES by a single OS
Insertion of an application for a PC station
Each PC station requires additional information for what purpose it is applied in the PCS
7 project (e.g. OS, OS server or client, Batch…).
The desired software component is represented as an object of type “WinCC
Application” and has to be placed like a hardware component:
• in the virtual rack of the Station Configurator
• in the HW config of the regarding station in the PCS 7 project
 The following phrase may give a hint:
The CPU of AS needs a partner on the PC: a "CPU of visualization" for the OS. This
is the job of the "WinCC Application". Following this analogy, the WinCC application
is placed in the hardware configuration of a PC station like a CPU in the AS rack.
Several WinCC Applications are available being specialized for different types of PC
stations (e.g. OS, OS server or client, Batch…)
An example for single OS stations is the application WinCC Application.

PCS 7 System Course
If you want to use the ES also as OS Single Station, then you have to extend the PC
configuration of ES by a WinCC application for single OS stations:
Configuration of network and connections

NetPro
Plant bus, IE
Image 1:1
OS
Communication connections (connections, for short) must always be configured, when
data exchange between the automation systems or the automation system and a PC
station (for example, an OS station) is required.
The figure above illustrates the relation between communication partners.
• The "true communication partners" are CPU of AS at the one side and the CPU of
OS / WinCC at the other side ( red point): they are the end of a "logical
connection".
• The CPs are interface of the network ( green line): they are the end of a "physical
connection".
Once the stations have been arranged and configured, the connections between the
ES/OS station and the automation systems, as well as those between the automation
systems themselves, are configured (as 1:1 image) and downloaded to the concerned
stations – just like the configuration of stations.

6.2 PC Station Configuration
6.2.1 PC Station Configuration on the PC
Select the PCinternal interface in your ES via the Dialog “Set PG/PC Interface” in
SIMATIC Manager:
Options -> Set PG/PC Interface
For a combined Engineering / Operator Station with a single network connection
• a network interface for Industrial Ethernet (CP or IE General)
• the WinCC Application
have to be added. You are free choosing a slot (see column "Index"), because it is "only
a virtual rack" for the PC.

PCS 7 System Course
6.2.2 PC Station Configuration in the project
In the project a SIMATIC PC Station is to be inserted:
It is to be renamed to the computer name.
This applies to all PC stations. The name of the PC station must match the station name
in the Station Configuration Editor, which already has the preset computer name.
 Rename the PC station so that its name matches that of the computer.
To do this, you can activate the "Computer name identical to PC station name"
option, which means you do not have to make as many entries and the potential for
typing errors is reduced.
A yellow arrow then appears on the PC station icon in the SIMATIC Manager to indicate
the capability of the ES to establish a connection to the plant bus via the "PC internal"
interface.
After renaming its configuration is to be opened:

PCS 7 System Course
On the same position as in the Station Configuration Editor an IE interface is to be
inserted and supplied with the proper addresses and network assignment:
After completing the configuration, it is to be saved and compiled and downloaded.

6.2.3 Function “PLC Configure”
From PCS 7 V7.0, the function „PLC configure“ provides a comfortable approach for
configuration of SIMATIC PC stations. With this function, you must no longer twice work
on the configuration (in the project on the ES and in the station configuration editor on
the local PC station).
However, there are important prerequisites:
• The PCS 7 software is installed on the station to be configured.
• The station has to be accessible in the network.

Procedure for configuration of PC station of the ES
1. Configure the SIMATIC PC station of the ES in the project (ending with a Save and
Compile, not a Download)
2. In SIMATIC Managers Component view, transfer the PC configuration of the project
to the PC by the function “PLC configure“. The virtual rack of Station Configuration
Editor is overtaking the PC configuration already prepared in the project.
3. Download of the configuration.

Entrance possibilities:
− In the Find field you can enter any text, catalog info or order number.
Not case sensitive
− wildcards (*, ?,….) are supported
− you can also enter a part of an key word (e.g. 331)
2. Using the pull down list “Profile“ you can select several catalog profiles.
You can adapt the profiles to your needs.
3. Object for the required module (in this case with a firmware version).
4. Information of the selected component
Versions
Many modules are available in different versions (Firmware versions).
During operation of a plant it may happen that you are forced to replace an older version
of a module by a new one with a higher version. In that case the old version remains in
the HW Config and the new module is placed.

PCS 7 System Course
Save and compile
At Save and Compile a consistency check is performed, e.g.:
• Do all modules fit to each other?
• Are addresses assigned twice?
This is the case in the result window below:
Download
When the consistency check is error free, the required system blocks are created,
without any user interference. After that they can be downloaded into the AS.
The AS contains all the required information to test if the real configuration fits to the by
HW Config created configuration.
I will be hidden for the user that many additional features are activated, so that in the
events of failures the related messages and alarms will be generated.
To download the HW Config data into the AS, the entire communication path from the
ES PC up to the Ethernet CP in the AS must be configured properly.
For the initial download into the AS, a number of configuration steps are to be done
using the tool NetPro. It will be explained in a later stage.

PCS 7 System Course
6.3.4 Configuring the CPU
SIMATIC PCS 7 uses default optimized settings for a CPU, so just a limited number of
properties are to be adjusted to the project conditions.
Startup properties
In the Startup properties the most important is the activated option “Warm restart“.
This causes the actual process values not to be reset to the initial values.
It is a default setting for PCS 7 that is not to be changed!
 Please note, that a PCS 7 AS is always to be equipped with a buffer battery and a
RAM memory card.

Organization blocks, cyclic interrupts and Process image partitions

1. List of OBs assigned to cyclic interrupts (grayed out = not available fort his CPU)
2. Interval of the cyclic interrupt
3. Assigned Process image partition (PIP)
Organization blocks (OBs) form the interface between the CPU operating system and
the user program. OBs are called by the operating system and control the cyclic and
acyclic program sequence, the startup behavior of the automation system and the
processing of faults.
Start events triggering some groups of OBs are called interrupts.
Cyclic interrupts do their job with predefined time interval. They are represented by
OB30 – OB38.
OBs also control the sequence of processing the individual program blocks. The
processing of one OB can be interrupted by another OB (determined by the priority).
Before any program run, the CPU loads the signal values of the input modules into a
memory, the Process Image Inputs (PII). Because of this PII, the signal values will be
constant during the program run. During the execution of the user program, output
values are assigned to the Process Image Outputs (PIQ). At the end of the program run,
the values of the PIQ are transferred to the output modules.
To control the update of the PII at the start of a program run triggered by a cyclic
interrupt, and the update of the PIQ at the end of a program run, the so called Process
Image Partitions (PIP) are assigned to the cyclic interrupts in use.
 In process automation with PCS 7, the Cyclic Interrupts (OB30-OB38) are to be used
with an assignment to a Process Image Partition.
The Process Image Partitions are required at the configuration of the signal modules.
Automation functions are “inserted” into the run sequence of an (Cyclic Interrupt) OB.

PCS 7 System Course
6.3.5 Configuring the Ethernet interface

4. Creating a new subnet object
5. List of available subnet objects
The connection to the plant bus is made by selection of the related subnet object in the
properties of the Ethernet CP.
When a multiproject has been created by the wizard, the project does not contain a
subnet object for Industrial Ethernet. The required subnet can be created in the
properties of the Ethernet interface.
On a with ISO protocol running plant bus, every MAC address can be assigned only
once.

2. External Profibus interface: is realized by the CP 443-5 Ext.
The module can be placed to have additional DP master systems.
3. Subnet: object for a Profibus net. In its Properties you can adjust the transmission
rate and the profile. Always assign a useful name (default: PROFIBUS(1)).
4. DP master system: All slaves assigned to a master form together with the master a
master system. A master system is a part of a PROFIBUS subnet.
5. Object for a Profibus slave. Distributed IO devices or field devices are assigned a
master system as a slave object. In case of a ET200M it can be the IM 153-2, for
connecting to the Profibus.
Every node (master and slave) is assigned a Profibus address (0…126)

PCS 7 System Course
Adding (inserting) and disconnecting, orphaned master systems
The internal Profibus interface is default assigned a DP master system. When more
Profibus CPs are available, then additional master systems are to be assigned.

1. External Profibus interface
2. Already existing DP master system
It may happen, an already completely configured master system is to be assigned to
another DP interface (e.g. from the internal Profibus interface of the CPU to the
additional CP 443-5 Ext).
In that case the master system is disconnected from the interface, and will be available
as an “Orphaned” master system. The configuration of the distributed IO will remain
unchanged.

PCS 7 System Course
Orphaned master systems are put into a list that will appear when you want to assign a
master system to a Profibus interface. In that way you can connect an existing master
system, including the included configuration of distributed IO to another Profibus
interface.

4. Connecting to the subnet
5. Adjusting Profibus properties.

PCS 7 System Course
For assigning Profibus addresses, only the for that subnet available addresses can be
used.
 A Profibus interface must not be assigned as a master system, but can still be
connected to a subnet. I that case the Profibus address is still in use.
Independent from separating the master system, you must disconnect the Profibus
interface from the subnet, before the address can be used by another node (another
Profibus interface).
Operating mode of the Profibus interface
Check in the Properties dialog, in tab “Operating mode”, if the DP mode “DPV1”is used.
The DP mode “DPV1” contains extensions for process automation.
More specific: acyclic data exchange for parameter settings, operating, visualization,
and interrupt control of intelligent automation devices, parallel to the cyclic data
exchange.
 With the setting DPV1 also DP slaves, not supporting DPV1 can be connected and
operated.

modules are used.

PCS 7 System Course
Configuring the ET200M interface module
Be sure, there is a check mark at “Replace modules during operation”.
 For use in PCS 7 the racks of ET200M should be equipped with active bus modules.
Configuring signal modules

1. Select useful names (diagnostics)
2. Select a Process Image Partition (PIP). It should have been set in a earlier stage in
the CPU properties of a cyclic interrupt OB. Doing so, the IO signals are
synchronized with the Process images due to the cyclic interrupt OBs.
This setting affects all channels of the module.

PCS 7 System Course
Diagnostics enabled
Modules with diagnostic recognize internal and external module faults and generate
diagnostic alarms.
With the enabling of the diagnostic interrupt, the diagnostic alarms will be generated
automatically through the PCS 7 drivers after an OS compilation.
Channel specific settings
In general, a channel of a module should only be activated, when the related sensor,
actuator or replacement resistor has been connected.
That is to prevent unwanted diagnostic messages on the PCS 7 OS in Runtime.
At some modules, channels are grouped to channel groups. In that case the settings are
common for the channels of the channel group, e.g. for the AI8x12Bit module: 4 groups
of 2 channels each. The group is to be activated when a signal is connected to 1
channel. Then a resistor is to be connected to the other channel.

6.3.11 Comparing PROFIBUS DP and PROFINET IO
Why PROFINET IO?
Future requirements regarding system performance and sizing will have field busses
reach their limits.
Because of continuous technological development Ethernet provides future-proof
communication platform with high performance.
Merging the areas office and automation, vertical integration offers productivity
improvement potential.
In the office sector, Ethernet is the unchallenged standard in the fields of installation
technology and protocols.

6.3.12 Configuring the IO Controller
Addressing
Profibus DP: Individual
addressing in each station
Profinet IO: Simple name designation
through Controller with support of
Engineering System
Before the distributed IO can be used by the central station it must have an address:
• For DP slaves: a number: 0 …126
• For IO devices: a device name
The device name can be assigned in different ways, e.g. by the HW Config tool of
STEP 7.
Initial Steps
Open the Properties of the Ethernet interface:
