Profinet - Siemens SIMATIC NET Manual

11 Example — PROFINET Communication with
OPC
Introduction
This example illustrates how to link an S7-300 programmable controller with a PC
station over a PROFINET communications processor.
You will see which tools to use for configuring a PC station and interfacing a
PROFINET device. You will also see how symbolic variables of PROFINET are
made available in OPC.
Initial Situation
If you want to try out the example yourself, you require the following:
S a PC
S a network adapter for Industrial Ethernet
S the SIMATIC NET CD 11/2003 software
S an S7-300 PLC with a CP 343-1 PN PROFINET communications processor
S Industrial Ethernet cabling between the PC module and S7 device
For the S7-300, you require a project created with the PROFINET tool
"SIMATIC iMap".
Creating a project engineering configuration with SIMATIC iMap is beyond the
scope of this description and is not included.
