SCALANCE XF204-2BA DNA

The SCALANCE XF204-2BA DNA from Siemens is a new compact switch specially designed for use with redundant SIMATIC S7‑400H systems in process automation. It follows the recommendations of NAMUR NE 21 and is therefore suitable for use in process automation. The switch with dual network access functionality (DNA or indeed Y-switch functionality) combines a redundant PROFINET ring consisting of S2 devices (field) with a high-availability PROFINET system (R1 system).

• Connection of up to two modular BusAdapters (2 ports each) supported
• Enclosure in SIMATIC ET 200SP design (slim design, 100 mm wide) for space-saving use in small control boxes
• Integrated redundancy manager for constructing Fast Ethernet ring topologies with fast media redundancy at the device end
• Integrated system diagnostics with PROFINET, SNMP access, integrated Web server and automatic e-mail transmission function for remote diagnostics and signaling via the network
