Siemens Junction Box

[Daisy Hughlett]

Inthe hardware settings for the Reference junction option whenever I choose "Internal Reference Junction" I get an overflow decimal value of 32767. When I change the option to "Fixed Reference Temperature" I get a reading and the reading changes in the right direction when I apply heat to the thermocouple.

I wire the thermocouple to a different channel and change the respective channel hardware setting to Internal Reference Junction and I the overflow value happens on that channel again. I swap out different thermocouples on the same channel and I get the same error.

Trust in precision

It uses accurate thermal impedance measurement in combination with automatic test equipment. Precise measurement of thermal response to a short power pulse allows high throughput semiconductor testing, including for junction-to-case thermal resistance verification. Junction temperature measurement is via electrical method using built-in Simcenter Micred T3STER technology.

Reach the gold standard

As an IC test handler picks and places devices for test, each device is qualified for automated binning compared to a gold standard thermal impedance curve and preset bandings of variation.

Activities included designing and building wind-powered boats, battery-powered cars, solar-powered robots, a wind turbine, and a sustainable city. In total, volunteers from Siemens Mobility, Network Rail, CK Contracts, Rail Systems Alliance and SPL Powerlines delivered the activities to around 70 pupils and received great feedback from the pupils and the teachers.

The day was filled with engaging activities for all ages, stages and needs. Evidence of skills for life learning and work were in abundance, from demonstrating creativity, working with others to showing initiative and adapting skills to a different environment...the list goes on!

As a major junction on the West Coast Main Line, where the lines from London Euston and Edinburgh to Glasgow Central merge, the Carstairs Junction modernisation will help to encourage more passengers and freight operators to use the railway in Scotland with safe, reliable, and future-proofed journeys.

The Trackguard Westlock and WTS digital signalling systems from Siemens Mobility will be at the core of the Carstairs Junction modernisation programme. Manufactured and developed in the UK, WTS connects objects to interlockings and control centres via an IP-based network, improving operational performance and management to provide safe, dependable, and future-proof travel.

Industry partners Siemens Mobility, CK Contracts, Rail Systems Alliance and SPL Powerlines are collaborating on a phased programme of investment on the key junction on the West Coast Main Line which will simplify and upgrade the track layout to clear the existing bottleneck on the network and enable the separation of non-stop passenger and freight trains from those stopping at the station.

From more resource-efficient factories, resilient supply chains, and smarter buildings and grids, to cleaner and more comfortable transportation as well as advanced healthcare, the company creates technology with purpose adding real value for customers.

The digital junction box SIWAREX DB guarantees by continuous integration, that data can be gathered and analyzed more comprehensive than never before. This data can be used optimally for targeted monitoring of weighing processes as well as for enhanced diagnosis and the simplification of services. Error reports for each connected load cell will be shown centrally at the SIMATIC controller or the HMI panel. Even the load of every individual load cell appears already during commissioning. SIWAREX DB offers the possibility, to connect a scale with up to four load cells and due to the digitalization of the well-established strain gauge technology it offers complete flexibility in the plant design. Using the SIWAREX WP231 as weighing module the seamless connection to a SIMATIC S7 CPU for SIMATIC S7-1200 is possible. Whereas for the distributed I/O system SIMATIC ET 200SP, the use of a SIWAREX WP321 as weighing module is the first choice. Due to the rugged housing with degree of protection IP66, the SIWAREX DB also suits for weighing applications in demanding industry environments.

Siemensbahn (German for "Siemens Railway") is an abandoned 4.5 km rapid transit line of the Berlin S-Bahn in Berlin. It was opened in 1929 as a modern, grade separated, third rail electrified, double track, heavy rail branch line serving three new train stations, and closed in 1980.

The Siemens & Halske company privately financed the line to improve worker access to its industrial district in the eponymous Siemensstadt locality of Spandau. Siemensstadt not only was home to production and research facilities, but a private town with social and childcare services, housing tracts, sports venues, allotments, churches, retail and leisure facilities, all designed to modern architectural and social standards with minimal municipal oversight.[1]

Planning and construction of the Siemens Railway were closely coordinated with Deutsche Reichsbahn and began in 1925 and 1927 respectively. Upon completion in 1929, Siemens handed ownership and control to Deutsche Reichsbahn for integration into the Berliner Stadt-, Ring- und Vorortbahnen ("Stadtbahn, Ringbahn and suburban railways") network. That newly electrified network was rebranded as the Berlin S-Bahn in 1930.

Towards the end of the Second World War, a bridge across the river Spree was destroyed, and one track subsequently removed as war reparations. By the time the line was fully restored in 1956, Siemens had relocated to Munich due to the division of Germany. Following the building of the Berlin Wall in 1961, the Deutsche Reichsbahn of East Germany remained in charge of a now bisected S-Bahn network. After decades of low ridership numbers and lack of investment, Siemensbahn fell into disuse in September 1980 when industrial action of East German railway personnel precipitated the abandonment of substantial portions of the West Berlin network.

The Siemensbahn north of the Spree crossing, including bridges, viaducts and ancillary buildings, is listed for conservation as a historic technical ensemble with the Berlin State Historical Monument Office (Landesdenkmalamt Berlin).[2] There are plans to reactivate the line to serve a new Siemens research campus at the old Siemensstadt site as well as new housing developments. An eventual extension beyond Gartenfeld was anticipated during the original planning of the line but so far has not materialized, despite various proposals having been put forward over the course of almost a century.

Siemensbahn connected to the Berlin Ringbahn at the existing Jungfernheide station. That station was partly rebuilt with an improved platform arrangement designed to handle high volumes of passengers without delaying Ringbahn services during shift change. Trains would mostly continue onto the Ringbahn towards the center of Berlin, or terminate at Jungfernheide.

Terminating trains stopped twice: First at the northern platform edge of eastbound center platform "B" for unloading and easy cross-platform interchange to Ringbahn trains, and then the southern platform edge of westbound center platform "C" for reversing the train at a buffer stop while simultaneously loading new passengers.[3][4]

Leaving the station in a western direction, the line passed under the westbound Ringbahn track and diverged north to cross the river Spree and continue onto an elevated alignment that is part steel viaduct, part on an embankment interspersed with steel or concrete road bridges.

The first intermediate station was Wernerwerk halt. Beyond Wernerwerk, the line curves to the west at a wide angle. Just before the next halt, Siemensstadt, the line begins a turn in a north-western direction. Beyond Siemensstadt halt, the line gradually descends to grade level. The single center platform of the Gartenfeld terminus was built mindful of a potential future extension of the line. Spanning some of the 1 km distance between Siemensstadt and Gartenfeld stations is a yard with six tail tracks that, in the early years, provided terminal and stabling capacity for up to twelve rush-hour trains, but was repeatedly scaled down in the following decades.

The interlocking at the terminus and yard was controlled from a gantry-style, brick-clad signal box with the designation "Gtf" (mnemonic for Gartenfeld). The electro-mechanical interlocking with multi-aspect colour light signals implemented automated and semi-automated modes to enable dense traffic of up to 24 trains per hour and direction (150-second theoretical headway). Colour light signalling can be more flexible and require less maintenance than semaphore signals but only became practical to use after the exhaust from steam locomotives no longer posed a risk of obscuring sightlines, so the electrified Siemensbahn was one of the first lines to be equipped that way. The interlocking was produced by Vereinigte Eisenbahn-Signalwerke (VES), a joint venture of Siemens & Halske's own railway equipment company with Allgemeine Elektricitts-Gesellschaft (AEG) and Eisenbahnsignal-Bauanstalten Max Jdel, Stahmer, Bruchsal.[5]
