PROFIBUS Network audit on one of the longest networks in the Netherlands

Filed under

A tunnel is actually a large cabinet you build around an installation. That is certainly true of the extension of the A4 motorway between Delft and Schiedam; the route has been there for years and the tunnel was built over it.

Last December I worked as a support employee in the PROCENTEC test team carrying out the network audit on this very special network. The stretch of motorway is actually 7 km long: 1 km at ground level, 2.6 km half-sunken, 1.4 km sunken and a land tunnel extending for 2 km. This resulted in an incredibly long PROFIBUS network where we had no less than 190 segments to check.

First electrical car ferry in the world in operation in Norway now using PROFIBUS

Filed under

The world’s first electrical car and passenger ferry powered by batteries has entered service in Norway. The ferry only uses 150 kWh per route, which corresponds to three days use of electricity in a standard Norwegian household. Built in conjunction with shipbuilder Fjellstrand, Siemens installed the complete electric propulsion system and put up charging stations with lithium-ion batteries which are charged from hydro power. With the change to battery, ship owner Norled is reducing the cost of fuel by up to 60 percent. The Norled ferry represents a milestone on the road to operating completely emission-free ferries along Norway’s long coastline, with at least 50 other routes currently able to sustain battery-operated vessels.

The integrated automation systems control and monitor the machineries and auxiliaries on the ferry and are connected via Profibus to all other subsystems.

Mobile debarking system relies on MVK Metal and PROFIBUS

Filed under

Fieldbus installation concepts using MVK Metal are well-established solutions for highly automated production lines. Sometimes, Murrelektronik's rugged fieldbus module is used in applications where you wouldn't quite expect it. A prime example is the Halder GmbH mobile debarking system. The machine builder, located in southern Germany, retrofitted their systems with MVK Metal, a modern Profibus fieldbus solution.

New laser-based R&D cell uses PROFIBUS for robotics & distributed IO

Filed under

A new laser-based research and development cell has been installed at the Manufacturing Technology Centre (MTC) in Ansty, West Midlands, to help keep British manufacturing at the forefront of assembly, fabrication, and joining technologies.

A Mitsubishi iQ-controller controls the laser, a six-axis test piece handling robot and multiple points of distributed I/O over Profibus connections.

PROFIBUS Monitor detects critical changes in the fieldbus system and prevents downtimes

Filed under

A breakdown of the fieldbus communication system can quickly become very expensive, particularly if it causes unplanned downtime of complex machinery like paper manufacturing facilities. To avoid network problems, it is essential to know the current age-related states of the installed PROFIBUS components. The PROFIBUS Monitor (BC-502-PB) diagnostics tool for the continuous monitoring of PROFIBUS networks supports the early detection of potential failures. In addition, the analysis data provided by the PROFIBUS Monitor can be used as the basis for scheduling preventive maintenance action during planned machine downtimes.

Automation Lessons Learned at Iron Bridge Water Plant

Filed under , ,

The City of Orlando’s Iron Bridge Water Treatment Plant. Bill Wood, Manager of the Industrial Automation Group, and Guy Mecabe, System Manager of Wastewater Systems, discussed their systems philosophy at the plant. The city owns and manages four large wastewater treatment facilities with associated remote pumping and lift stations. The Iron Bridge plant was originally built in the 1980s to treat about 5 million gallons of wastewater per day. After several modifications and upgrades, it can now treat and reclaim up to 40 million gallons in that same 24-hour period. The facilities standardized on Siemens controls, drives, power distribution, and Profibus and PROFINET communications network.

PROFIBUS Helps with UK Flood Control

Filed under

Two concrete towers stand 20 meters above the ground at the UK Environment Agency's Dartford Barrier Flood Defence System in Kent, England. The barrier is routinely closed in conjunction with the bigger Thames Barrier upstream to prevent high tide water in the River Thames flowing back up the creek and flooding Dartford and the surrounding area.

Much of the equipment the control system spoke to was PROFIBUS- or Siemens-based. Two PROFIBUS Master communication modules (MVI56-PDPMV1) from ProSoft Technology were installed inside ControlLogix PACs to facilitate communications.

Herb Elliott Port and Rail Infrastructure

Filed under

Against the backdrop of an emerging minerals resources boom driven by the economic transformation of China and India, plus, restricted access to existing rail and port facilities, Fortescue was forced to build its own rail and port infrastructure to take advantage of Asia’s growing demand for Iron Ore. In partnership with engineering firm WorleyParsons, construction at the Herb Elliott Port commenced in November 2006 on reclaimed swampland, and first deliveries of iron ore from Cloudbreak mine were uploaded and stockpiled ready for export in April 2008.

PROFIBUS Crane Monitored with COMbricks

Filed under

Attero's automation team in Moerdijk, Netherlands has installed a COMbricks module in the PROFIBUS network of one of its cranes to eliminate cable breakages and EMI issues. The company annually burns over 1 million tons of household waste and converts the heat created into hot steam for the Essent power station next door.
