SCALANCE SC636-2C provides 4x electrically powered ports at 10/100/1000 Mbit/s RJ45, 2x combo ports, address translation (NAT/NAPT), and connection to SINEMA RC. It is specifically designed to protect devices and networks in discrete manufacturing and process industries, ensuring industrial communication with a firewall. SCALANCE S is optimized for use in automation environments and industrial settings, meeting the specific requirements of automation technology, such as easy upgradeability of existing systems, straightforward installation, and minimal downtime in case of failures. It protects industrial automation networks from unauthorized access and establishes a DMZ (demilitarized zone), enabling data exchange with other networks without granting direct access to the production network. The integrated firewall controls and filters traffic, providing protection against misuse, preventing unauthorized access, and avoiding disruptions and communication overload. It allows for seamless integration into existing networks without the need for reconfiguration of end devices or the establishment of new IP subnets. Comprehensive protection is ensured through a flexible cell protection concept. The devices are robust and designed for industrial use. Accessories include comprehensive software, interchangeable media, FastConnect connectors, stripping tools, plug transceivers, and cables that perfectly complement the system.
