This chapter describes in detail the startup of a communication connection between a
SIMATIC S7 and WinCC. The communication connection is realized via the Industrial
Ethernet. The communication card CP 1413 used in the computer has its own CPU
onboard. This will free the CPU of the computer from communication tasks. Such a
configuration is generally referred to as Hardnet.
Overview of the Structure of the Sample
On the computer side, the connection to the Industrial Ethernet network is established via
the communication processor CP 1413. To install this communication processor in the
computer, the driver IE S7 1413, located on the SIMATIC NET CD-ROM, is needed.
In the WinCC project, the communication driver SIMATIC S7 Protocol Suite must be
installed. Via its channel unit Industrial Ethernet, the connection to the SIMATIC S7 is
configured.
The PLC is equipped with a CPU 416-1 module. The connection to the network is
established via the communication processor CP 443-1. For the configuration of this
communication processor with the STEP7 software, the option package NCM S7 Industrial
Ethernet is required.

Testing of the hardware configuration made.
If the key switch of the CPU module is set to RUN or RUN-P and the operating
mode switch of the communication processor is set to RUN, only the status LEDs
signifying the RUN operating mode should be displayed.
If this is not the case, there is an error. The following steps help you localize this
error. However, these steps should still be performed even if the status LEDs

This chapter describes in detail the startup of a communication connection between a
SIMATIC S7 and WinCC. The communication connection is realized via the Industrial
Ethernet. The CP 1411 communication processor used in the computer has no separate
CPU, the computer’s CPU handles all communication tasks. Such a configuration is
generally referred to as Softnet.
Overview of the Structure of the Sample
On the computer side, the connection to the Industrial Ethernet network is established via
the communication processor CP 1411. To install this communication processor in the
computer, the driver IE SOFTNET-S7 BASIC, located on the SIMATIC NET CD-ROM, is
needed.
In the WinCC project, the communication driver SIMATIC S7 Protocol Suite must be
installed. Via its channel unit Industrial Ethernet, the connection to the SIMATIC S7 is
configured.
The PLC is equipped with a CPU 416-1 module. The connection to the network is
established via the communication processor CP 443-1. For the configuration of this
communication processor with the STEP7 software, the option package NCM S7 Industrial
Ethernet is required.

This chapter describes in detail the startup of a communication connection between a
SIMATIC S7 and WinCC. The communication connection is realized via the Industrial
Ethernet. As the transport protocol, the TCP/IP Protocol will be used.
Overview of the Structure of the Sample
On the computer side, the connection to the Industrial Ethernet network is established via
the communication processor CP 1411. To install this communication processor in the
computer, the driver IE SOFTNET-S7 BASIC, located on the SIMATIC NET CD-ROM, is
needed.
In the WinCC project, the communication driver SIMATIC S7 Protocol Suite must be
installed. Via its channel unit TCP/IP, the connection to the SIMATIC S7 is configured.
The PLC is equipped with a CPU 416-1 module. The connection to the network is
established via the communication processor CP 443-1 TCP. For the configuration of this
communication processor with the STEP7 software, the option package NCM S7 Industrial
Ethernet is required.

This chapter describes in detail the startup of a communication connection between a
SIMATIC S7 and WinCC. In this sample, the communication connection is realized via the
Industrial Ethernet. By making only slight changes, the communication via the PROFIBUS
is also possible.
The S7 OPC Server running on the computer makes the data of the PLC available to other
applications running on the same computer and to applications running on the network. The
S7 OPC Server communicates with the PLC via the communication processor CP 1413.
Overview of the Structure of the Sample
On the computer side, the connection to the Industrial Ethernet network is established via
the communication processor CP 1413. To install this communication processor in the
computer, the driver IE S7 1413, located on the SIMATIC NET CD-ROM, is needed. In
addition, the S7 OPC Server, also located on the SIMATIC NET CD-ROM, is needed.
In the WinCC project, the communication driver OPC must be installed. Using this OPC
Client, the connection to the S7 OPC Server is configured.
The PLC is equipped with a CPU 416-1 module. The connection to the network is
established via the communication processor CP 443-1. For the configuration of this
communication processor with the STEP7 software, the option package NCM S7 Industrial
Ethernet is required.

will free the CPU of the computer from communication tasks.
Overview of the Structure of the Sample
On the computer side, the connection to the Industrial Ethernet network is established via
the communication processor CP 5412 A2. To install this communication processor in the
computer, the driver PB S7-5412, located on the SIMATIC NET CD-ROM, is needed.
In the WinCC project, the communication driver SIMATIC S7 Protocol Suite must be
installed. Via its channel unit PROFIBUS, the connection to the SIMATIC S7 is configured.
The PLC is equipped with a CPU 416-1 module. The connection to the network is
established via the communication processor CP 443-5 BASIC. For the configuration of this
communication processor with the STEP7 software, the option package NCM S7
PROFIBUS is required.

the communication processor CP 1413. To install this communication processor in the
computer, the driver IE TF-1413, located on the SIMATIC NET CD-ROM, is needed.
In the WinCC project, the communication driver SIMATIC S5 Ethernet Layer 4 must be
installed. This communication driver is used to configure the connection to the SIMATIC
S5.
The PLC SIMATIC S5 115U is equipped with the CPU module CPU 944. The connection
to the network is established via the communication processor CP 1430 TF. For the
configuration of this communication processor, the communication package SINEC NCM
for COMs is required.

Creation of a program block for the communication.
The communication to WinCC via the communication processor CP 5431 is
carried out by calling the data handling blocks SEND and RECEIVE. For the
SIMATIC S5 115U PLC used in this sample, these are the blocks FB244 and
FB245. These blocks must be called once every program cycle. As the request
number A-NR, 0 is assigned to these blocks to allow execution of the Send All
and Receive All functions.
In this sample, the data handling block calls are carried out in a program block,
which is called in the OB1.
In STEP5, the creation of a new program block is carried out via the Editor
STEP5 Block
menus of the program file. As the name of the program block,
this sample uses PB5.

During the call of the function block, the interface number SSNR of the CP 5431
is transferred as a parameter. As the RADR parameter, the PROFIBUS address of
the communication processor CP 5412 A2 in the computer is specified. In this
sample, this is 8.
In addition, the connection parameters of the instruction types used must be
specified. On the one hand, these are the parameters RVC4 and RVC5, which
indicate the Service Access Points of the WinCC station. These SAPs are
specified in WinCC during the creation of the connection. On the other hand,
these are the parameters ANR4 and ANR5. These are the instruction numbers,
which have been set during the configuration of the FDL connections for the
communication processor CP 5431. For both instructions, the numbers of the
work-DBs must be indicated as well.
The remaining call parameters of the FB9 are not important for the functionality
of this sample.

10.1 Configuration of the WinCC Stations
The following description contains notes that should be observed during the configuration
of the WinCC stations.
In general, three configurations for the access from a WinCC client station to an OPC
server are possible. These configurations differ, depending on where both components are
located:
• Server and client are located on the same computer
• Server and client are located on different computers of the same workgroup
• Server and client are located on different computers within the same domain or in
different domains with trust setting
The first of the configurations mentioned is not practical for the communication between a
WinCC OPC server and a WinCC OPC client. However, this configuration can be applied
to other cases, e.g. for the communication to the S7 OPC Server.
For the steps described below, the conditions existing on site must be considered.
• A: Installing the Software Components

If a workgroup is used, ensure that the user of the client station is known on the
server station. Additionally, the user of the server station must also be known on
the client station in order for the full functionality of OPC to be utilized.
If the domain concept is used, this must not be remembered, because all users are
known in the entire domain. However, for the access to a server station across
domains, a mutual trust setting on both domains is required.
