Configuring Lifebeat Monitoring for an OS Client

Configuring Lifebeat monitoring for an OS client is not difficult. There are severalsteps that need to be taken. Here is an outline of those steps.

When in doubt, the online help for WinCC Manager is the best resource. Notethat specific PDF files can be access from the help system with regards toDCOM, OPC and Lifebeat Monitoring.

The general sequence of steps to be taken are:

1. Create an OPC connection channel for the client to be monitored;

2. Add the client to the Lifebeat monitoring list in the Server OS in WinCC;

3. Verify the settings for DCOM on the client.

Verifying DCOM on the Client Computer

1. Verifying DCOM is not always necessary, however the author has seeninstances where the default client installation was not compatible withLifebeat Monitoring.

2. On the client computer, from the start bar, open Control Panel –Administrative Tools – Component Services.Expand out the component services tree to display the DCOM servicesinstalled on the client computer.If any windows pop up asking if you want to register DCOM componentsto Windows, select Yes.

3. Navigate the DCOM component tree to OPCServer.WinCC.

4. Right click on OPCServer.WinCC and select Properties.

5. The most important detail is Authentication Level. If set to None, Lifebeatmonitoring will not work for that client.

Set the value to “Connect” from the drop down box.

6. Select the Security Tab to set access permissions.

By Default, only Everyone will be listed as permitted DCOM access users.The online documentation recommends adding the usersADMINISTRATORS, INTERACTIVE, NETWORK and SYSTEM.

This would be for avoiding any Windows user authentication issues orprivilege levels.

7. Do the same for Launch Permission.

8. Lifebeat monitoring should work.
