Use the Kernel with a Selected Process

If a Plant SCADA process is running, the Kernel window can be used to diagnose the runtime information for that process.

To enable the Kernel to be launched from Runtime Manager, you need to confirm following settings:

• The Citect.ini parameter [Debug]Menu needs to be set to 1. By default, this parameter is set to 0 which means the Kernel menu option will not be available.

  You can also use the Setup Wizard to configure this setting. Run the Setup Wizard, select Custom mode, and select the Kernel on menu option on the Control Menu Security Configuration page.

• Users who access the Kernel need to be assigned to a Role that has the Kernel Access property set to "Full Access" or "Read Only". A Read Only user can access the Kernel, but cannot perform some privileged commands like running Cicode.

  Note: If you attempt to display the Kernel for a display client process from Runtime Manager, it will not succeed if no one is logged in or the current user is assigned to a role with Kernel Access set to "No Access". An error message will be displayed in this case.

To view the Kernel for a process:

1. In Runtime Manager, right click on the process for which you would like to view the Kernel window.

2. Select Kernel from the context menu which appears.

3. The Kernel window for the selected process will appear and a login dialog will display. Enter a valid user name and password (see above).

Dump Kernel Data for a Running Process

You can dump Kernel data for a running process directly from the Runtime Manager.

4. Right-click the running process.

5. Select Dump Kernel.

When complete, the message "Kernel data has been dumped successfully" is displayed. Kernel data for only one process may be dumped at a time. Kernel data is dumped in non-verbose mode. This menu option can be disabled by setting the INI parameter [RuntimeManager]AllowDumpKernel to 0.
