Auto logout PLC activity pulse?

Auto logout PLC activity pulse?

The auto logout facility will of course logout an inactive user.
An active user will touch the screen, Zenon sees this and resets the internal timer for auto logout.
However, Zenon is but one small part of the machine. The machine also has pushbuttons, dials, guarding, doors, all of which the present human interacts with. None of these actions reset the internal timer. So even if the operator is present and doing their job, just not touching the HMI, they are still going to be logged out because they should have known to touch the screen.
How can I easily take an activity pulse generated in the PLC up into Zenon so Zenon can use it as evidence the operator is still present?
