The Bridge remote access system allows a TAIT engineer to troubleshoot your automation system remotely from anywhere in the world. Note that this is a separate system than provide in the Nav:RS4.
The system starts with the hardware located inside your Motion Control Rack (MCR). The hardware consists of a din-rail mount TAIT Bridge and a Draytek NAT router/firewall. The Draytek router accepts a hard-wired external ethernet network connection or can act as an ADSL modem direct to a phone line. A WiFi to ethernet gateway can also be supplied if no hard-wired ethernet connection is available.
The TAIT Bridge establishes an open HTTP(S) connection to the Heartbeat Server. It awaits a connection request from an engineer, relayed via the server. When the connection request is received, the Bridge establishes a VPN tunnel to the Heartbeat Server. The engineer also establishes a VPN connection to the Heartbeat Server, which links the two connections to allow the engineer remote access to any component on the automation network.
TAIT operate multiple heartbeat servers located across the globe. The specific server used is chosen based on the lowest latency between the remote system and server. This means the specific IP address of the server used is subject to change.
The ‘bridge’ system requires an active hard-wired internet connection with the following outgoing ports to any IPv4 address permitted:
TCP 80 (HTTP)
TCP 443 (HTTPS)
TCP & UDP 123 (NTP)
TCP & UDP 22 (SSH)
UDP 1194 (VPN)
UDP 1195 (VPN)
UDP 1196 (VPN)
UDP 1197 (VPN)
