Windows-based operator panel as of 170 series with Ethernet interface
Note: The OP270 and TP270 do not have an on-board Ethernet interface. You can use a CF Ethernet card to extend the OP270 and TP270 by an Ethernet interface.
2. Configuring the CP 243-1 with STEP 7 Micro/WIN The settings for the CP 243-1 are defined in STEP 7 Micro/Win via the Ethernet Wizard. For assistance with all the information go to STEP 7 Micro/WIN Online Help via F1.
No.
Procedure
1
Starting the Ethernet Wizard
Open STEP 7 Micro/WIN.
Start the Ethernet Wizard via "Tools > Ethernet Wizard...."
Click on "Next".
Fig. 01 - Ethernet Wizard
2
Confirm message
Click "Yes" to confirm the message that appears.
=> Your STEP 7 Micro/WIN configuration is compiled, and the symbolic addressing is activated.
Fig. 02 - STEP 7 Micro/WIN message
3
Specifying module position If your PC is connected to the S7-200, click the "Read modules" button to determine the position of the CP 243-1 module automatically. Otherwise, the module position can also be entered manually.
Important:
WinCC flexible Runtime or the Windows-based operator panel can only establish a connection with a CP243-1 if the module is configured to "position 0". The TSAP for the remote station must be set to 02.00.
Check if the CP is connected in the module position "ZERO" and change the module position if necessary.
Identify or enter the module position "ZERO".
Click on "Next".
Fig. 03 - Enter module position
4
Specifying IP address
Define an IP address for the CP 243-1.
Caution:
The IP address for this application may not be taken automatically from a server because the WinCC flexible Runtime or the Windows-based operator panel requires a fixed reference partner (CP 243-1) for the Ethernet communication.
Note: The communication connection type for this module can be defined by the "Automatic Setting".
Click on "Next" to continue.
Fig. 04 - Set IP address
Note:
The BOOTP server is a pared-down DHCP server.
5
Parameterizing PtP connection
Specify the command byte for the module and the number of point-to-point connections with the CP 243-1.
Click on "Next".
Fig. 05 - Number of connections
6
Configuring connection
The configuration for connecting the CP 243-1 to WinCC flexible Runtime or to a Windows-based operator panel must be defined as in Fig. 06.
Click OK to confirm the entries.
Warning:
The TSAP must always be specified in four-digit format, with a leading zero (02.00).
Fig. 06 - Configuring connections
7
Using CRC protection Set the CRC protection the way you want it. It is advisable to work without CRC protection first of all. The "Keep Alive Interval" can be specified with the default time.
Activate the CRC protection and change the time of the "Keep Alive Interval" if required.
Click on "Next".
Fig. 07 - CRC protection and Keep Alive Interval
8
Assigning memory
Specify a memory area for the configuration of the CP 243-1.
Recommended:
If you click on Suggest address, the Wizard can identify a variable memory area.
Click on "Next".
Fig.08 - Memory for the configuration
9
Creating project components If you click on "Close", the Ethernet Wizard generates the project components for the set configuration. Among other things, subprograms and the variable memory are created in the data block.
Click the "Close" button.

10
Confirm message
Click "Yes" to confirm the message that appears.

11
Call ETH0_CTRL
In your STEP 7 Micro/WIN program, you must call the ETH0_CTRL subroutine in each cycle.
Finally, load the entire configuration into the S7-200.

3. Configuring a WinCC flexible PC Runtime
No.
Procedure
1
Creating a PC project
Run WinCC flexible.
Create a project with the device type "PCs > WinCC flexible RT".

5
Start WinCC flexible Runtime
Once you have completed the configuration in WinCC flexible, you can start the Runtime.
4. Configuring a Windows-based operator panel The connection to the S7-200 must be configured in the WinCC flexible project. You must parameterize the configuration of the Ethernet adapter directly in the operator panel.
