We use Wonderware Intouch for Terminal Services. One instalaltion is with Windows Server 2000, it is running for 5 years now and never failed. We also have a new installation with Intouch 10.0 for TS with Industrial Application Server running on Server 2003, using 2 servers and Network Load Balancing and it is running since one month.
For VPN, almost any VPN solution that will allow Micrososft Remote Desktop Protocol (RDP) will let you connect to TS session via Internet. We use Cisco VPN and Fortinet SSL VPN Tunel.
The key is to get a SCADA software version clearly compatible with Terminal Services.
For remote access I use MobiKEY from Route1 inc (route1.com) For local I have used TS and RDP .. only issue is the connectivity to the PLC's/devices and whether they support it.. Rockwell doesn’t.. due to copy protection - unless its changed within the last year or so.
I have built custom apps to serve up data in various formats using TCP etc so that the session get the data external from the PLC comms app.
