to be connected to the CPU-for-Panel, remove the IO/COM Bus
connector cover.
3. Plug the CPU-for-Panel into the HMI Panel AUX connector. If an
adjacent module is already installed, slide the CPU-for-Panel
into place via the guide tunnels shown in the accompanying
figure.

the CPU-for-Panel have snapped onto the DIN-rail structure on
the back of the panel.
