1.7 Networking Stations with STEP 7
Configuring
To allow stations to communicate with each other the networks must be configured
in the STEP 7 projects.
Configuring a network or subnet involves the following:
1. You create one or more subnets of the required subnet type in the project.
2. You select the properties of the subnet. Normally the default settings are
adequate.
3. You connect the station “logically” to the subnet.
4. You set up connections for communication.
Networking in a Multiproject
STEP 7 as of Version V5.2 supports configuration in a multiproject.
Using a multiproject, for example, you can create a project for distributed editing by
various editors and distribute the stations to the projects according to their editors.
To allow this, functions are available for branching and merging (sub) projects.
Interproject subnets and connections can be created.
Tools
The SIMATIC Manager provides convenient tools for configuring and documenting
networks (also graphically with NetPro).
The chapters describing network configuration in /6/ and the online help system
also contain information about configuring SIMATIC S7 networks.
