No.

Procedure

1

Select the "SIMATIC Shell" folder (final entry under "My Computer") in the Windows Explorer.

2

The computers are displayed in the navigation window, in the tree under the "SIMATIC Shell" item.
If this is not the case, check the order of the network adapters in the Control Panel under "Network Connections > Advanced > Advanced Settings...". The network card for terminal bus communication must always be at the top of the "Connections" list if you are using multiple network cards in your target station.

3

In the navigation window of the "SIMATIC shell", right-click the "SIMATIC shell" item and select "Settings..." in the pop-up menu that opens.. The "Select Terminal Bus" dialog opens. Check that the correct network adapter is set as access point for the terminal bus. Change the setting if necessary.

Notes:

• The network adapter configured for the terminal bus is shown in blue in the "Network Adapters" list if you click on another network adapter.
• After opening the "Select Terminal Bus" window, the network adapter with access to the terminal bus is shown marked with a bar (selected) in the "Network Adapters" list. This is the reason why the network adapter configured as terminal bus is not displayed in blue. This is why it is not clear to see at first glance which network adapter is assigned to the terminal bus. If you now select another network adapter in the "Network Adapters" list, the network card originally configured for the terminal bus is displayed in blue.
  
  Warning
  By selecting another network adapter you have simultaneously changed the assignment of the network adapter for the terminal bus. If you click the "OK" button to close the window, the "Reinitialize" dialog opens. Here you click on "Yes" to accept the currently selected network adapter as access point for the terminal bus. The the "No" button you retain the network adapter originally selected for the terminal bus.
