April 18, 2017 - Siemens offers Scalance XF-200BA, a line of Profinet switches. The use of various bus adapters allows users to set up electrical and optical line, star and ring structures. Bus adapters are available with RJ45, SCRJ and LC connection systems. Two types of switches are available: Scalance XF204-2BA, a standard switch for universal, cross-industry use, and the Scalance XF204-2BA DNA Y-switch for special tasks in process automation. A temperature range from -40 to +70° C together with approval for use in hazardous areas (ATEX Zone 2, IECEx) allow use, even in harsh environments.
Both versions support up to four ports and various firmware-functionalities. For example, virtual LANs (VLANs) divide the physical network into several virtual sections to minimize the number of broadcasts in the network. Redundancy protocols such as Highspeed Redundancy Protocol (HRP) and Media Redundancy Protocol (MRP) permit an availability of machines and plants: If the communication fails, there is a switchover to the redundant path within milliseconds.
Additional functions, such as Link Aggregation and Remote Network Monitoring (RMON), round out the firmware range of the Scalance XF-200BA line of products. The switches are characterized by a compact enclosure that was developed following the design of the Simatic ET 200SP HA. As well as mounting on a wall or a standard rail, the Scalance XF-200BA is ideal for mounting in a control cabinet alongside the new Simatic ET 200SP HA. Siemens is exhibiting the product line, together with the new version of the Simatic PCS 7 V9 process control system, at the Hannover Messe 2017.
All these components are networked with the Scalance XF204-2BA and XF204-2BA DNA switches, which are equipped with coated printed-circuit boards (Conformal Coating). They also meet the requirements of NAMUR/NE21, which specifies the immunity requirements for process and laboratory control equipment. The Scalance XF204-2BA DNA also offers Y-switch functionality for connecting S2 devices to a R1 system.
