Ethernet
7.1 Overview
Explanation of the Configuration Example
This example illustrates how you can connect an S7-400 programmable controller
with a PC station over Industrial Ethernet.
In the configuration example presented here, typical communication partners are
connected to Industrial Ethernet and can be reached over the OPC server.
Example of an Industrial Ethernet Configuration
Communication takes place between two devices or modules. Communication with
an S7-400 station using the S7 protocol is described in detail below.
You will see which tools are used for planning a PC station in the project
engineering for connecting to an S7-400. You will see how symbolic variables in
the S7 program are made available in OPC. You will also see how to use the OPC
Scout program that is supplied with the product for communication with the OPC
Server.
