The devices can also be integrated into redundant network infrastructures. Supporting two redundancy protocols for Layer 2 and Layer 3 eliminates the need for additional switches on the security transitions. The Media Redundancy Protocol (MRP) enables the SC-600 to be integrated on the Layer 2 level as Profinet devices in the Profinet ring redundancy without needing an additional managed Industrial Ethernet switch. In the event of a ring break, all network components in the ring switch to the redundant path within 200 ms and thus avoid a production stoppage in the event of a fault. Furthermore, the support of the Virtual Router Redundancy Protocol (VRRP) allows redundancy on Layer 3. This enables users to group the Scalance SC-600 together with other routers in the network in one logical group. If the router defined as the master fails, another router in the logical group takes over the function of the default router. The network consequently continues to communicate reliably.
The third innovation is support for user-specific firewalls. Specific firewall rules allow not only device-specific but also user-specific filtering of the data. This enables users to assign differing rights. Users consequently benefit from easier access management for network components.
Support of all device versions in the new Sinec NMS network management software allows the complete, uniform configuration of all the Scalance network components on a management platform. Use of the digital input together with the signaling contact allows, for example, the activation and deactivation of the VPN tunnel via the management platform for remote networks, Sinema Remote Connect.
