Compact and flexible code reading system for industrial applications
The new Simatic MV420 stationary 1D/2D code reading system from the Siemens Industry Automation Division is characterized by high reading reliability, a compact design, and a wide range of communications and connection options.
The compact device with high IP67 degree of protection can read both standard high-contrast codes as well as DPM (direct parts marking) codes even under difficult ambient conditions. Typical uses include product tracking and process control applications in the automotive, packaging, pharmaceuticals, tobacco, cosmetics, electronics, and food and beverage industries. In addition, the new reading system is also suitable for shipment tracking in logistics and distribution.
The Simatic MV420 1D/2D code reading system with 640 x 480 pixels resolution has an integrated M12 lens and supports operating distances from 1 to 22.5 centimeters. The operating distance is adjustable using an integrated focus. In addition to its integrated lighting, an external lighting unit may also be connected. The Simatic MV420 processes up to 40 codes per second. Using multi-code reading, several codes and even different code types can be decoded from a single image. This is advantageous, for example, when bulk-reading several stacked items.
A special feature is the "auto trigger" image recording mode. This enables the code reader to record images continuously at maximum speed while simultaneously evaluating them. The reader recognizes the relevant codes in a sequence of any duration without requiring external trigger signals, such as those from a light barrier. This feature is particularly suitable for slow-moving objects and in applications where precise triggering using a light barrier would be difficult.
The Simatic MV420 features integrated Profinet IO, Industrial Ethernet, and RS232 interfaces. A communications module is used to connect to Profibus DP, which also allows mixed operation with RFID (radio frequency identification) systems. It is controlled by the same function block in the Step7 program.
The Simatic MV420 code reading system is parameterized and commissioned using a built-in Web server. To do this, a PC or programming device with Internet Explorer is used. No additional software is required. For most applications, the parameters are automatically preset. The Web-based user interface provides extensive operator control and monitoring functions, even in evaluation mode.
In addition, HMI (human-machine interface) devices are also suitable for displaying the image information. Application-specific user interfaces are created using visualization software such as Simatic WinCC or WinCC flexible. Numerous diagnostics, logging, and evaluation functions are also available. For example, time stamps, error patterns, and result values can be archived in database systems to create trend analyses or statistics.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
