Programmable logic control device with integrated database driver

Abstract: The invention relates, in particular, to an automation system ( 10; 110 ), in which a programmable logic control device ( 20; 120 ) can be connected via a network ( 100; 200 ) to a database system ( 60; 160 ). So that the programmable logic control device ( 20; 120 ) can exchange data directly with the database system ( 60; 160 ), the programmable logic control device ( 20; 120 ) has a first driver module ( 42; 132 ) associated with a physical interface ( 50; 150 ) for controlling data transmission via the network ( 10; 110 ) and also a second driver module ( 41; 132 ) for controlling the data exchange with the database device ( 60; 160 ).

Tension spring clamp fitted to current rail

Abstract: The clamp has a housing (1) receiving the current rail (2) and a spring metal clamp spring (4), with a bearing arm (5) acting against a bearing surface (3) of the current rail and a front arm (10) with a window through which the front end (12) of the current rail projects. A screwdriver blade (18) is inserted in an operating shaft (14) for the clamp housing at an angle to a conductor insertion shaft (13), for moving the front arm of the spring to open a conductor insertion gap between the current rail and the edge of the window.

A Low-Cost and Energy-Efficient Smart Dust Cleaning Technique for Solar Panel System

Abstract: Dust accumulation or soiling is a major challenge faced by the solar farm which are in the desert areas where the solar resource is available in plenty. Dust can be classified as any particles on the panels which blocks the sun’s irradiance from reaching the solar cell. Soling is more prominent in solar farm which are placed in non-arid environment (Desert Regions). The performance of the Photovoltaic Systems is greatly affected by dust accumulation or soiling. Current methods used in the markets are costly, labour based, involves periodic battery replacement, more water usage, immense mechanical components and requires cyclic maintenance. This paper presents a low cost, energy efficient, smart dust cleaning technology for PV Panels, which shall mitigate the local climatic challenges in solar farm. The cleaning system is designed, automated using Programmable Logic Controller (ILC 131 ETH) which controls the devices used in the cleaning system and tested successfully. Particularly, the proposed solar cleaning system is expected to enhance the system efficiency of the Solar panels in the United Arab Emirates (UAE) and other Gulf Cooperation Council (GCC) countries which have climatic conditions of dusty weather conditions.

Ladestation zur Abgabe elektrischer Energie an einen Empfänger elektrischer Energie

Abstract: Die vorliegende Erfindung offenbart eine Ladestation (10) zur Ubertragung elektrischer Energie an einen Energieempfanger, mit – einem Ladestecker (50) zur Kopplung mit einer korrespondierenden Verbindungsvorrichtung des Energieempfangers und zur Ubertragung elektrischer Energie, wobei der Ladestecker (50) mit der Ladestation (10) mittels eines Versorgungskabels (60) elektrisch gekoppelt ist; und – einer in der Ladestation (10) angeordneten Halteeinrichtung (14) zum Halten des Ladesteckers (50) in einer Parkposition, wobei die Ladestation (10) dadurch gekennzeichnet ist, dass diese ferner eine Kuhleinrichtung (20) aufweist, mittels der der in der Parkposition befindliche Ladestecker (50) kuhlbar ist.

Method for the failsafe operation of a process control system with redundant control devices

Abstract: The invention relates to a process control system (5) that has at least one OPC client (22) and an OPC server (30) which communicate via a standard OPC interface (31). The process control system (5) further has at least two redundantly operated control devices (40, 45), each of which communicates with the OPC server (30) via a coupling device (33, 34). Each control device is designed to provide process variables and status information. The status information includes the current role of the respective control device (40, 45), said current role being that of either a main control device or an auxiliary control device. The OPC server (30) is designed to detect the main control device (40) in response to the status information of at least one of the control devices, to register a variable list generated by the OPC client (22) at the main control device (40), and/or to merely transmit the process variables which have been provided by the main control device (40) to the OPC client (22).
