Supervisory system with remote access over the Internet (h)

The control system topology is same as in the previous example, the only difference is that the PC with web client is connected over the router. As the SCADA server is accessed over the Internet, network security should be highly considered.

The solution requires coordination with the customer’s IT department or with the connectivity provider. There will be an extra router in the specification, please contact the IT staff or Internet provider.
