Siemens expands optical code reading systems

08 April 2011

In the field of 1D/2D code reading systems, Siemens Industry Automation & Drive Technologies is expanding its portfolio for industrial identification with a new variant of the Simatic MV440 reader

All the MV440 models also have new functions, such as power over ethernet (PoE) or the verification license "Veri-Genius". Innovations such as the Profinet IO device replacement as well as the automatic recognition of code type and number have even been applied to the smaller Simatic MV420 model.

The "ultra high resolution" variant with a resolution of 1600 x 1200 pixels is new to the Siemens family of Simatic MV440 code reading systems. Previously, devices were available with resolutions of 640 x 480 or 1024 x 768 pixels. The higher resolution gives a particularly wide field of view, enabling up to 150 individual, or particularly large, codes to be read simultaneously. With the OCR license (Optical Character Recognition) "Text Genius" customers can expand the functional scope of the new device to include text recognition.

Furthermore, Siemens has added PoE throughout the Simatic MV440 product group. This means that power, picture data and even time-critical data can be transmitted over a shared cable, which reduces the cabling outlay considerably. With the industrial ethernet switches Scalance X108 PoE/X308-2M and PoE/XR324-4M, Siemens is also offering the corresponding network components for drawing power from the ethernet cable.

Under the new firmware version 4.0 upwards, users can retrofit all Simatic MV440 variants with the verification function for checking the marking quality of the code with a separate license "Veri-Genius". This can be downloaded through the Simatic Automation License Manager to every MV440 device that is equipped with the new firmware. The latest firmware version also covers the most recent AIM specification AIM-DPM-1-2006.

A further innovation for Simatic MV440 and MV420 code readers is Profinet IO device replacement. This reduces the configuration work to a minimum following replacement of a defective device, resulting in lower maintenance costs and minimal downtime for the plant. It is also possible for the Simatic MV440 and MV420 SR-P code readers to automatically detect the number of codes and their types immediately, which means that dynamic code types can be used.

As a consequence of their new functions, the Simatic MV440 and MV420 code readers are opening up new application areas. These include scanner applications such as reading codes from packaging units that are being rotated by a robot in front of the reader. Further examples are gate applications in master/slave mode in which the master code reading system rejects codes that have been read multiple times by the slaves, which results in faster processing of the scanned data.

Under the name of Simatic Ident, Siemens Industry Automation & Drive Technologies offers a comprehensive product portfolio for industrial identification. The Simatic Ident offering comprises RFID systems as well as optical code reading systems. The stationary 1D/2D code reading systems, Simatic MV420 and Simatic MV440, are characterised by their high-speed and reliable reading performance – even under severe environmental conditions in industrial use.

With versatile lighting options, a wide selection of communication and connection possibilities, and their compact size, the Siemens code readers are suitable for a wide range of industrial applications. Simatic MV420 and Simatic MV440 are used by companies operating in different sectors, such as the automobile, packaging, pharmaceuticals, tobacco, cosmetics and electronics industries, as well as in applications in the food and beverage sector.
