Re: Remote overview
Disconnect the SCADA system from the network completely.
Connect a PC or use the LCD control panel to display important statuses and alerts.
Aim a CCTV camera at th estatus screen (and if you wan tto go really fancy get it to alert on signifacnt changes in certain areas). Get the remote users to view via CCTV. Any issues they drive to site.
If you need to react quicker then allow a physical connection to be hooked up only once the issue is assessed and only for the minimum period of time necessary (then pull the plug again).
