Description: In this description of how to configure S7 connections it is assumed that all the stations are in one S7 project.
Types of S7 connections: With S7 connections you differentiate between bilaterally configured and unilaterally configured S7 connections.
Bilaterally configured S7 connections You recognize bilaterally configured connections by the fact that they receive a connection ID at both endpoints. The partner ID can be identical for both connection partners, but doesn't have to be. The remote endpoint of the S7 connection created is entered automatically in the connection table on the partner side.
You can use the following communication blocks in the S7-300 or S7-400 station for data communication via bilaterally configured S7 connections:
FB/SFB14 "GET" and FB/SFB15 "PUT"
FB/SFB12 "BSEND" and FB/SFB13 "BRCV" or
FB/SFB8 "USEND" and FB/SFB9 "URCV"
Unilaterally configured S7 connections Unilaterally configured S7 connections are configured on the module that actively sets up the S7 connection.
You can use the communication blocks FB/SFB14 "GET" and FB/SFB15 "PUT" in the S7-300 or S7-400 station for data communication via unilaterally configured S7 connections. You can use these for data communication via unilaterally and bilaterally configured S7 connections. You can only use the communication blocks FB/SFB12 "BSEND" and FB/SFB13 "BRCV" and FB/SFB8 "USEND" and FB/SFB9 "URCV" for data communication via bilaterally configured S7 connections.
More information on the properties and special features of the S7 protocol and on the properties of the different S7 protocol services is available in Entry ID: 26483647.
In NetPro there is a connection table with all the configured communication connections. Unilaterally configured S7 connections have no entry in the "Partner ID" column of the connection table. This field remains empty in the connection table. No S7 connection is configured on the server and no communication blocks are called. The server is managed independently by the CPU's operating system and has resource 0x03. No system data is created for this in the connection partner.
Fig. 1: Bilaterally and unilaterally configured S7 connection
Summary:
All S7 connections that have a connection ID at both connection endpoints are bilaterally configured S7 connections.
S7 connections that have no partner ID are unilaterally configured S7 connections or have been created via "unspecified" S7 connections with resource 0x03.
Important:
With bilaterally configured S7 connections you must load the configuration in both connection partners after creating the S7 connection.
With unilaterally configured S7 connections you must load only the one station in whose connection table the S7 connection is shown.
Note: In the sample S7 connection configuration given above all the stations are in one S7 project. You can also set up an S7 connection to an unspecified partner and the endpoints of these connections can be in different projects. More information on this is available in the Online Help of STEP 7:
Configuration notes:
In version V6.1 of SIMATIC NET (CD 11/2002) and higher you can use the symbol table and the data block symbols of your STEP 7 project as a basis for generating the symbols of the SIMATIC NET OPC server.
This entry describes how to generate symbols for the SIMATIC NET OPC server from the STEP 7 symbol table.
A PC station with a standard Ethernet network card is used. Data exchange between PC station and S7 station is implemented via Industrial Ethernet using S7 Communication.
Requirements: Both PC station and S7 station must be configured in the same STEP 7 project.
Configuration of the S7 station: Use the SIMATIC Manager to open your STEP 7 project that contains the SIMATIC S7 station.
Fig. 01: STEP 7 project
Switch to the S7 program folder and double-click on "Symbols". The symbol table opens.
In the symbol table you define the symbol names you want.

QUESTION:
What do I have to consider when connecting a PC to a S7-300 and
S7-400?
ANSWER: In figure 1 you see a configured connection from an OPC-Server
to a SIMATIC 400 and an unconfigured connection from a OPC-Server
to the SIMATIC 300.
Figure 1 Connection configuration in NETPRO
Figure 2 Configured connection (S7 400)
Figure 3: Unconfigured connection (S7-300)
In figure 2 you can see that a bi-directional connection has
been configured for the SIMATIC 400.
In figure 3 you can see that a uni-directional connection has
been configured for the SIMATIC 300.
After the connection has been established the configuration has
to be transferred to the PC station.
Detailed informationen about this topic can be found on the
SIMATIC NET CD under "Advanced PC Configuration"
ATTENTION:
The configured connection has to be transferred also onto the
S7-400 station.
Explanation:
When configuring a connection to a S7-400 in NETPRO, the project
has to be transferred to both stations, here the "PC_Station" and
the "SIMATIC 400", with "Load to station". This is called a
configured connection. The S7 connections that have been defined on
the server as well as on the client side - e.g. from the PC to a AS
S7-400 station - are called also bi-directional connections.
When configuring a connection to a S7-300 in NETPRO, the project
has to be transferred only to the PC station. This is an
unconfigured connection. S7 connections that are defined only on
the client side - e.g. from a PC to an AS S7-300 station - are also
called uni-directional.
