B&R presents a simple and secure option for remote maintenance

Service technicians can access machines from anywhere in the world. In addition, a certified and encrypted VPN connection is established between the SiteManager on the machine and a gateway, which is usually located at the machine manufacturer's service center. There, all access rights for up to 10,000 machines are stored. A comprehensive machine pool management system can be set up easily. Integrated firewall

The SiteManager has integrated digital inputs and outputs. These could be used to connect a key switch, for example, that must be actuated to permit access for maintenance. An integrated firewall provides protection against unauthorised third-party access. In order to avoid conflicts with plant firewalls, communication to the Internet is handled using firewall-compatible encrypted Web protocols. No additional ports must be opened. Connection is via LAN, WLAN or mobile network.

All the diagnostics and maintenance functions of the B&R system can be used via a secure VPN connection. The SiteManager is easy to configure in B&R's Automation Studio engineering software, making it well suited for both series-produced or retrofit machines. In cases where a LAN or WLAN connection is not possible or not desired, the VPN connection can be established via a GPRS and UMTS mobile network. This ensures optimal service even for facilities in remote locations without the expense of dispatching a field technician.
