Kernel Access Improvements

Access to the Kernel has been changed to provide improved security while monitoring a runtime system. These changes also allow you to display the Kernel from Runtime Manager while running Plant SCADA as a service.

You can still launch the Kernel on a display client in the following ways:

• From the Control menu (see Display the Kernel from the Control Menu)

• Via the Cicode function DspKernel (see Define a Runtime Command)

• From the Runtime Manager (see Use the Kernel with a Selected Process).

To display the Kernel window for a display client, the user that is currently logged in now needs to be assigned to a Roles 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: The special Kernel user that enabled Kernel access in previous versions no longer has default access to the Kernel window.

To display the Kernel window for a server process (including when running Plant SCADA as a service), you will need to log in using the dialog that is displayed when the Kernel window is launched.

You will need to enter a user that is assigned to a Role that has the Kernel Access property set to "Full Access" or "Read Only".

Note: Before commissioning a system, it is recommended that you review the Kernel Access setting for each Role. This will avoid accidental or unauthorized use of the Kernel.
