Why will the WinCC clients not communicate with the WinCC server?
This may be due to the fact that the terminal bus has been configured incorrectly. If the computer has multiple network cards, for example, ensure that the correct network card is configured for access to the terminal bus.
Use the "Simatic Shell" tool to configure the terminal bus on all the computers involved, including the WinCC servers.
|1||Open "Simatic Shell"|
Navigate through the Windows Explorer to the Simatic Shell. You will find the "Simatic Shell" in the Windows Explorer under "My Computer > Simatic Shell". Right-click "Simatic Shell" to call up the pop-up menu and select the "Properties" entry.
You can find detailed information in the WinCC Online Help under "WinCC Information System > Configurations > Multi-User Systems > Remote Configurations".
|2||Select the network adapter for the terminal bus|
Select the appropriate network card in the "Network adapters" area which is used to access the terminal bus and check the network settings.
|3||Check the "CCAgent" service|
Go to "Start > Control Panel > Administrative Tools > Services" to check whether the "CCAgent" service is started.
