1.1 Overview
Introduction
In automation technology, more and more old systems have to be upgraded step
by step from SIMATIC S5 to SIMATIC S7.
Normally, partial migration is done by successively replacing the S5 stations of an
old system by a SIMATIC S7 station. However, the communication relations to
other SIMATIC S5 stations have to be maintained.
These examples shall demonstrate how to link a SIMATIC S5 station to a modern
SIMATIC S7-1500 station via Industrial Ethernet. This example describes the
scenarios for ISO on TCP protocol.
Overview of the automation task
The figure below shows a frequently occurring communication structure of existing
S5 systems.
