11 Remote Tool Access (OZW)
With Remote Tool Access, Siemens provides users, with "Service Level" (or
higher) access rights, simple and secure access to the OZW web server.
The plant can be serviced at any time, from anywhere.
Remote Tool Access establishes a secure tunnel connection to the web server via
Synco IC. The connection is used for tool access:
● By ACS
● By ETS
● Simple and fast set up of Internet access - no fixed IP address, forwarding over
a dynamic IP address, or port forwarding (NAT/PAT) required
● The same view and operations as direct on-site access
● Encrypted connection
● No open ports on the router
● No need to open the firewall
● Access is to OZW only and not the entire LAN
