Redundant connections via Industrial Security Appliances 

Delays or failures can cause high losses in the production. Ensure network security in your plants thanks to redundancy and constant availability of the devices. This is possible by use of SCALANCE SC-600 Industrial Security Appliances with Virtual Router Redundany Protocol (VRRP) and Firewall State Synchronization. Redundant connections can be ensured via VRRP. If the master router fails, the backup router with VRRP takes over. With Firewall State Synchronization, all active connections of the master are always transmitted to the backup router as well. The firewall is immediatly running: siemens.com/scalance-s
