Click the "Compile" button.

2.2Configuring the PC Station

Before you start configuring the PC station in the TIA Portal, determine or changethe IP address of the network card that you are using in your PC station. You enterthe IP address and subnet mask of the network card when you configure the PCstation in the TIA Portal.

Determine and change the IP address and subnet mask of the network card

In Windows you open the "Network and Sharing Center" and select the "Changeadapter settings" functions. Open the Properties dialog of the network card towhich the S7-1200 is connected.

In this example the network card receives the IP address 172-16.40.11 and subnetmask 255.255.0.0.

Note

The IP address configured for the PC station in the TIA Portal must match theIP address set in Windows. If you are not using a router, the IP addresses of thePC station and the S7-1200 CPU must be in the same subnet.

Open the "Device View" of the PC station in the devices and networks editor

In the project tree, navigate to the device folder of the PC station,

"PC Station [PC station]", for example. The device folder contains structuredobjects and actions that belong to the device.

In the device folder double-click the "Device configuration" object to open the

"Device View" of the devices and networks editor.

In the hardware and network editor you select the Device view. Here you configureand parameterize the modules of the PC station.

The "Hardware catalog" task card contains the user applications and

communication modules that you can configure in the PC station. Using drag-and-drop you add the "IE General" communication module to Slot 1 and the "OPCserver" user application to Slot 2 of the PC station.

Define IP address and assign subnet

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

networks editor opens.

In the Network View or Device View of the devices and networks editor you clickthe PROFINET interface of the network card in the PC station.

In the inspector window you switch to the "Properties" tab. In the area navigationselect the "Ethernet addresses" item.

In this example you enter the IP address 172.16.40.11 and subnet mask255.255.0.0 for the network card.

Select the subnet that you have already assigned to the S7-1200 CPU and assign

it also to the network card of the PC station.

Note

The IP address configured for the PC station in the TIA Portal must match the IPaddress set in Windows. If you are not using a router, the IP addresses of the PCstation and the S7-1200 CPU must be in the same subnet.

The connection between the subnet, PN/IE_1, for example, and the S7-1200 andthe PC station is now displayed in the "Network View" of the

devices and networks

editor.

Displaying and Changing Properties of the S7 Connection in theInspector Window

Proceed as described below to have the properties of the S7 connection displayedin the inspector window.

In the table area switch to the "Connections" table and select the configured S7

connection. In the inspector window you switch to the "Properties" tab.

General properties

In the area navigation select the "General" item to display the connection path.The S7 connection is between the OPC server and the S7-1200 CPU.

In the area navigation select the "Special connection properties" item.

Here you see a display of the special connection properties of the local end point,"Active connection establishment", for example.

In this example, the OPC server establishes the S7 connection. The

communication partner, S7-1200 CPU, is participates passively in establishing the

connection.
