Configuration Notes
The CP443-1 (6ES7443-1EX20-0XE0 V1.0) is the successor product to the CP443-1 (6GK7443-1EX11-0XE0).
The delivery release of CP443-1 (6GK7443-1EX20-0XE0 V1.0) is available in Entry ID: 26685738. According to the delivery release the CP443-1 (6GK7443-1EX20-0XE0 V1.0) can be configured as from STEP 7 V5.4 SP3 plus Hardware Support Package (HSP).

When replacing module CP443-1 (6GK7443-1EX11-0XE0) with CP443-1 (6GK7443-1EX20-0XE0) you must modify the hardware configuration of your S7-400 station in STEP 7 in order to be able to use the additional functions of CP443-1 (6GK7443-1EX20-0XE0).

If the CP443-1 (6GK7443-1EX11-0XE0) is configured in STEP 7 V5.4 SP3 and is replaced with a CP443-1 (6GK7443-1EX20-0XE0 V1.0), the parameters listed below are not adopted automatically:

• The configured MAC address.
• The configured IP address.
• The configured subnet mask.
• The information about which network the module is connected to.
• The fixed settings of the Ethernet port.
• Connection information of the S7 connections in NetPro.

Proceed as follows for replacing the CP443-1 (6GK7443-1EX11-0XE0) with the CP443-1 (6GK7443-1EX20-0XE0 V1.0) in STEP 7 V5.4 SP3.
 

No.	Procedure
1	Open the hardware configuration of the S7-400 station where the configured CP443-1 (6GK7443-1EX11-0XE0) is to be replaced with the CP443-1 (6GK7443-1EX20-0XE0). Double-click on the CP443-1 (6GK7443-1EX11-0XE0) located in the rack. The Properties dialog of the CP opens. Fig. 01
2	In the Properties dialog of the CP you click on the "Properties" button. The "Properties - Ethernet Interface CP443-1" dialog box opens. Fig. 02
3	In this example the following IP address parameters are defined for the CP443-1 (6GK7443-1EX11-0XE0): MAC address: 08-00-06-01-36-01 IP address: 140.90.36.1 Subnet mask: 255.255.0.0 The module is connected to subnet "Ethernet(3)". In the "Properties - Ethernet Interface CP443-1" dialog you define the IP address parameters for the CP443-1 (6GK7443-1EX11-0XE0). Fig. 03
4	Note the IP address parameters that are defined for the CP443-1 (6GK7443-1EX11-0XE0).
5	Replace the configured CP443-1 (6GK7443-1EX11-0XE0) with the CP443-1 (6GK7443-1EX20-0XE0), i.e. select the CP443-1 with order number 6GK7443-1EX20-0XE0 in the Hardware Catalog under "SIMATIC 400 > CP-400 > Industrial Ethernet > CP443-1" and drag-and-drop this to the configured CP443-1 (6GK7443-1EX11-0XE0) in the rack. Fig. 04
6	When you replace the CP443-1 (6GK7443-1EX11-0XE0) with the CP443-1 (6GK7443-1EX20-0XE0), the "Properties - Ethernet interface PN-IO" dialog opens. Fig. 05 Note The IP address parameters set for the CP443-1 (6GK7443-1EX11-0XE0) are not adopted automatically for the CP443-1 (6GK7443-1EX20-0XE0), i.e.: The MAC address configured for the CP443-1 (6GK7443-1EX11-0XE0) is deactivated. A default IP address with associated subnet mask is assigned for the CP443-1 (6GK7443-1EX20-0XE0). These IP address parameters are different to those configured for the CP443-1 (6GK7443-1EX11-0XE0). The CP443-1 (6GK7443-1EX20-0XE0) is not assigned to any subnet.
7	Manually set the IP address parameters noted in Step 4 and close the "Properties - Ethernet interface PN-IO" dialog with "OK". Fig. 06
8	Now the message below is displayed. Fig. 07 Acknowledge this message with "No". This completes module replacement in the hardware configuration.

The additional functions of CP443-1 (6GK7443-1EX20-0XE0) mean that there are more dialogs in the Hardware Configuration for the configuration of the CP443-1 (6GK7443-1EX20-0XE0) than for the configuration of the CP443-1 (6GK7443-1EX11-0XE0). There are three other dialogs in addition to the Properties dialog with CP443-1 (6GK7443-1EX20-0XE0):

1. PNIO - Properties of the PN-IO interface
2. Port1 - Properties of the first LAN port
3. Port2 - Properties of the second LAN port

With the CP443-1 (6GK7443-1EX20-0XE0) the dialog for setting the address parameters is no longer available in the Properties dialog of the module, but in the Properties dialog of the PN-IO interface. You can see this clearly in the following figure.
