1Introduction

This entry shows you how to configure an S7-1200, a PC station and an S7

connection in the TIA Portal so that you can exchange data between the stationsover Industrial Ethernet.

Note

In the TIA Portal you need STEP 7 Professional, because with STEP 7 Basic youcannot configure a PC station, but only the SIMATIC S7-1200.

Creating a Project

In Windows, select the command "Start > All Programs > Siemens Automation >TIA Portal V12" to start the TIA Portal.

In the Portal view, select the "Create new project" action.Enter the project name in the appropriate field.

2Procedure for S7-1200 up to firmware V3

This chapter shows:

How you configure an SIMATIC S7-1200 and a PC station in TIA Portal How you project an S7 connection for data exchange between SIMATIC

S7-1200 and PC station

2.1Configuration of the S7-1200

You configure your S7-1200 station in the TIA Portal. Then you create the userprogram and define which data is to be monitored over the S7 connection of theOPC server.

2.1.1Configuring the Hardware

Add an S7-1200 Station

In the project tree, double-click the "Add new device" item. The "Add new device"dialog opens.

Figure 2-1

SiemensAG2015Allrightsreserved

Click the "Controllers" button in the working area. Go to "Controllers >

SIMATIC S7-1200 > CPU" and select the required controller. Click the "OK" button

to add the selected S7-1200 CPU to your project.

Define IP address and assign subnet

In the project tree, double-click the "Devices & networks" item. The devices and

networks editor opens.

Figure 2-3

In the Network View or Device View of the devices and networks editor you clickthe PROFINET interface of the S7-1200 CPU.

In the inspector window you switch to the "Properties" tab. Select the "Ethernetaddresses" item in the area navigation.

In this example you enter the IP address 172.16.43.1 and the subnet mask255.255.0.0 for the PROFINET interface of the S7-1200 CPU.

Then assign a subnet to the PROFINET interface. Click the "Add new subnet"button to insert a new subnet.

Figure 2-4

The connection between the subnet, PN/IE_1, for example, and the S7-1200 is

now displayed in the "Network View" of the devices and networks editor.

2.1.2Creating a User Program

Add a data block

In the project tree, navigate to the device folder of the S7-1200 CPU,

"PLC_1 [CPU 1212C …]", for example. The device folder contains structuredobjects and actions that belong to the device.
