With the FL MGuard RS Firewall, Phoenix Contact provides an industry firewall/router solution for individual protection of distributed automation systems.
The devices are specifically designed for use in a harsh industrial environment and, unlike security solutions in the office environment, they meet the high requirements that automation poses for data transfer and mechanical robustness.
A central firewall that protects the entire company network does not provide protection against damaging activities that most frequently arise from within the network. Production cells can only be protected by a concept that works at a distributed level, based on a solution for providing end device security. The FL MGuard Firewall is a product line that provides the automation system with comprehensive protection from unauthorized access.
The security devices in the ME45 housing can be mounted on DIN rails and are integrated in the network as an independent system. There, they protect a part of the installation’s network or an individual automation component without affecting the system to be protected. All inbound and outbound data packets are monitored based on predefined rules.
When machines of the same design are operated in parallel within a network, previously every machine had to be individually configurable in order to be integrated in the higher-level communication system. The FL MGuard components support the 1:1 NAT function, allowing production cells with an identical IP address space to be used in a higher-level network. This means that it is no longer necessary to configure such standard machines individually.
