QUESTION:
What settings do I have to make to be able to practice teleprogramming with STEP 7 via Industrial Ethernet?

ANSWER:
You wish to practice teleprogramming in STEP 7 via Industrial Ethernet (ISO Industrial Ethernet, TC/IP protocol). You must meet the following requirements for ISO Industrial Ethernet:

1. Install a network card.
2. Install the "Softnet IE S7" or "Softnet IE PG" software from the SIMATIC NET CD.
3. Now set the "ISO Industrial Ethernet" protocol in the network settings.
   Windows 9x:
   The "ISO Industrial Ethernet" protocol is located in the network settings under "Protocols" at "Siemens AG".
   Windows NT:
   The "Siemens ISO Industrial Ethernet" protocol is in the network settings of your computer.
   Note: 
   From SIMATIC NET CD 7/2001 no protocol installation is required in Windows 2000 or Windows XP (from SIMATIC NET CD 11/2002).
4. Open the Control Panel via "Start >Settings > Control Panel" and double-click the icon "Set PG/PC Interface".
5. Set the access point "S7(ONLINE)STEP7" to "ISO Industrial Ethernet > Network Card".
6. Start the SIMATIC Manager.
7. Load your offline project via MPI into the controller and go online by clicking the "Online" button in the SIMATIC Manager.
   Note: 
   CPs of the *X11 series do not have to be loaded via MPI, because they have been equipped ex works with a permanently set MAC address. This then also provides a direct loading function via Ethernet.

If you are using Industrial Ethernet (TCP/IP), then the same settings are valid for Windows NT and Windows 9x as for ISO Industrial Ethernet:
Note: 
Here, too, from SIMATIC NET CD 7/2001 no protocol installation is required in Windows 2000 or Windows XP (from SIMATIC NET CD 11/2002), because this already be done to a great extent by the operating system.

1. Install a network card.
2. Install the "Softnet IE S7" or "Softnet IE PG" software from the SIMATIC NET CD.
3. Now add the "TCP/IP protocol" to the network settings of your computer if the protocol is not yet available.
4. Open the Control Panel via "Start > Settings > Control Panel" and double-click the icon "Set PG/PC Interface".
5. Set the access point "S7ONLINE (STEP7)" to "TCP/IP->Network Card".

6. Now start the SIMATIC Manager.
7. Load your offline project via MPI into the controller and go online by clicking the "Online" button in the SIMATIC Manager.
   Note: 
   CPs of the *X11 series do not have to be loaded via MPI, because they have been equipped ex works with a permanently set MAC address. Here, since STEP 7 V5.1 SP 2, using the function "Assign Ethernet Address" it is possible to assign an IP address via the DLC protocol. This then also provides a direct loading function via Ethernet.

Warning:

• In the case of older CPs, the Hardware Configuration must be loaded into the controller via MPI.
• CPs of versions up to and including version EX10 can only be addressed via your address after you have loaded the offline project into the controller.
