Versatile switch in a compact design

- Scalance XM-400 product line with two basic devices and two port extenders allows flexible configuration of switches for any application
- Optical and electrical connections on the same device
- Compact construction in modern Simatic S7-1500 design

Siemens Industry Automation Division is expanding its portfolio of Industrial Ethernet switches with Scalance XM-400. The new product line comprises two basic devices for connecting up to 16 (Scalance XM416-4C) or eight (Scalance XM408-8C) network stations, such as controllers from the Simatic range.

Both devices are equipped with electrical RJ45 ports and optical SFP slots which are designed for bandwidths of 1 Gbps. Siemens also offers port extenders, which can be connected without the need for tools, that extend the basic devices with additional connections for up to 24 network stations.

This means that users are able to configure switches to suit all applications, which reduces the costs per port as well as the space requirements. An optional key plug also activates Layer 3 functionality which supports static and dynamic routing and enables the storage of configuration data.

Scalance XM-400 is used to structure Industrial Ethernet networks and to connect automation components via networks in plants in the manufacturing and process industries. Typical sectors include the automotive industry, pharmaceuticals, chemicals, logistics, building management and transport.

The Scalance XM416-4C basic device for up to 16 network stations is equipped with 16 electrical RJ45 ports and four SFP slots for the use of optical plug-in transceivers. This therefore provides four so-called combo ports that can be used either electrically or optically. Scalance XM408-8C offers eight combo ports for up to eight network stations, that is eight RJ45 ports and eight SFP slots. Port extenders that can also be connected in just a few steps during operation (hot-swappable) are available in a variant with eight SFP slots and a variant with eight electrical RJ45 connections. If SFP single-mode transceivers are used, distances of up to 200 km can be bridged.

For fast and convenient network diagnostics of the switches using a web browser (Web Based Management), the IP address of the respective device can be read out locally by means of NFC (Near Field Communication). Scalance XM-400 features various redundancy functions, such as RSTP (Rapid Spanning Tree Protocol), MSTP (Multiple Spanning Tree Protocol) and ring redundancy, and supports the standby function for passive network sections when two HRP rings are coupled in a redundant configuration. The switches can also be used to operate virtual networks, so-called VLANs (Virtual Local Area Networks).

As power supply unit, Siemens offers the PM1507 load power supply for Scalance XM-400 which supplies the basic device and port extender with 24 V DC. Thanks to their compact construction in Simatic S7-1500 format, the new switches can be attached seamlessly to this Siemens controller on the standard rail.

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions

Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.

They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...

Im Focus: Mars' oceans formed early, possibly aided by massive volcanic eruptions

Oceans formed before Tharsis and evolved together, shaping climate history of Mars

A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million...
