Assigning network connection parameters

This task can be skipped if the CP 343-1 ERPC has already had its IP address, subnet mask and network gateway parameters configured.

It is assumed that you have started the STEP 7 program, have configured a SIMATIC S7-300 station and added the CP 343-1 ERPC module to the hardware configuration.

1. From the STEP 7 main window, open the appropriate project, select the appropriate SIMATIC S7-300 station configuration and double-click its Hardware icon.
   
   
2. The Hardware Configuration (HW Config) for the SIMATIC S7-300 station window appears.
   
   The station window lets you specify an IP address, subnet mask and network gateway parameters.
   If the network is part of an existing Ethernet company network, ask your network administrator for this information.
   
   
3. Double-click X1.
   A Properties window appears.
   
4. Make sure the General tab has the focus.
   
   
5. Click the Properties button.
   Assigning network connection parameters
   Properties for Ethernet interface window appears.
   
   
6. Make sure the Parameters tab has the focus.
   
7. In the IP address field, type the IP address to use for the CP 343-1 ERPC module.
   When you run the deviceWISE firmware loader, this is the IP address that will be used to connect to the CP 343-1 ERPC module.
   
8. In the Subnet mask field, add the appropriate subnet mask value for the network.
   
9. Under Gateway, make sure the Use router option is selected, and then type the IP address value of your network gateway.
   You might receive a message about your IP address and subnet mask. If so, click OK to close the message.
   
10. Click OK.
    You are returned to the HW Config window.
    
    You are now ready for Setting the initial time of day for the SIMATIC S7-300 station.
