Standardized Communication Structures in Detection Systems of Deutsche Bahn
The system DBMAS (DB-Meldeanlagensystem) is a new standardized solution for remotely controlling and monitoring alarm systems and further operationally relevant infrastructural facilities which has been called for tenders by DB AG in 2009. Facilities to be connected include amongst others hot box detection systems in the track area, wind sensor systems on bridges and dams, and safety devices of railway tunnels.

Automotive
With the industry-wide trend towards horizontal and vertical integration, intelligence is moving from the supervisory control systems to the local components. This development is leading to a growing need for communication for which the open OPC-UA standard provides an ideal solution because it can also be used for embedded devices. Softing’s embedded OPC-UA server gateway echocollect UA links the control world with the IT world and provides access to process, manufacturing and quality data in more than 50 different controller types.

Chemical Manufacturing
Saudi Arabian Fertilizer Company (SAFCO), a division of Saudi Arabia Basic Industries Corporation’s (SABIC), produces, processes, manufactures, and markets the principal fertilizers found in local and international markets.
In August of 2012, a number of heavy industry locations in the Middle East suffered a serious cyber attack. As a result, many of the companies in the region disconnected their manufacturing and process plant networks from their corporate networks.

Energy Monitoring
For optimal energy management of municipal buildings, it is necessary to be as informed as possible via rapid-response energy monitoring systems to report consumption of water, electricity and heat. The region around the city of Aachen, Germany, together with their premises management and the IT service provider regio iT has therefore introduced e2watch, which is based on advanced data logging technology from Beckhoff.

Oil & Gas
The Texas reputation for size comes with some mighty metrics to back it up. As the largest oil producer in the Union, the state’s wellheads are spread over 268,000 square miles. If you are in the oil and gas industry, on-site management and monitoring of land-based wells can be a logistical challenge as well as a considerable expense. The state boasts nearly one working oil or gas well for every square mile, each requiring stringent monitoring and reporting by the Railroad Commission of Texas, the governmental regulatory agency that oversees the state’s oil and gas industry.

Neste Jacobs is the Nordic region’s leading provider of technology, engineering and project services for the oil and gas, biorefining, petrochemicals and chemicals industries, including also the utilities and life science sectors. Prosys OPC Services has worked with Neste Jacobs to add the new OPC UA communication protocol to Advanced Process Control system and real-time process database (Case 1). Prosys has also provided an extension to Neste Jacobs’ NAPCON® Simulator – a training simulator system with hard control and alarm switches. Integration of the switches was based on OPC UA, which guarantees reliable communication and easy connectivity, as well as supports future expansions of the systems (Case 2).
