Any method to view the DCS (800xA) over web?
Are the following works possible in ABB 800xA when taken over web?
1. Should be able to view and migrate through the screens.
2. Should have user access to write values. (ex. set points, switching on/off of motors etc).
3. Should be able to view existing alarms and history too.
Thnks & regards,

Have you looked at MS RD gateway?
Most smart phones and tablets support VPN tunnelling. Hence its no big thing to setup a VPN server on the border of the 800xA system to allow trusted clients to connect via VPN over Internet; after the tunnel has been established workplaces etc can be launched in regular RDP sessions using some RDP app on the device.
For added security, remote sessions can be directed to a dedicated terminal server located on a DMZ. This server may require different user names and more complex passwords and be given less authority in the control system.
Personally, I've set a VPN server at home so that I can reach all of my IT equipment from Internet, etc. Within cell coverage, I'm just one tap away from accessing anything on my home network.
(disregard the IM apps, its the icon in the top/middle I wanted to show)
