Compact and flexible code-reading systems are reliable, fast and versatile
The recently introduced stationary, one-dimensional/two-dimensional (1D/2D) code readers from Siemens' Industry Automation Division are characterised by their reliability and speed as well as by the built-in communication interfaces and connection options that they offer.
Several versions of the Simatic MV440 1D/2D code reading system are available, says the firm. Systems are available with integrated lighting, to operate at a distance of up to 0.8 m; with external lighting, for a working distance of up to 3 m; with and without verification; and with a resolution of 640 x 480 or 1024 x 768 pixels.
The Simatic MV440 reads up to 80 codes per second, reliably detecting up to 15 types of code that have been stored in the device's memory. This 'multi-code reading' feature enables up to 50 codes to be decoded every time an image is recorded, which is useful when bulk-reading several objects that are stacked one on top of the other.
The 'auto trigger' function enables the code reader to simultaneously record images permanently (at maximum speed) and evaluate them. The reading device looks for codes in a sequence of images of any length, without the need for any external triggering signals, for example, from a light barrier. This function is particularly suitable for slow-moving objects and in applications where precise triggering by a light barrier is difficult to implement.
Using the Simatic MV440 verifier version, it is possible to measure the quality of the code - ensuring that the quality does not fall below a critical value over the entire production process and that in spite of possible contamination the codes are always detected reliably.
The Simatic MV440 has integrated Profinet IO, Industrial Ethernet and RS232 interfaces. For connection to Profibus DP, a communication module is required. The code-reading system's built-in Web server is used to set up parameters and for commissioning purposes. Users employ a personal computer or a programming device that runs Internet Explorer. No additional software is needed, and for most applications, the parameters are pre-set automatically. Moreover human machine interfaces make it possible to display image information. Customised user interfaces can be created using visualisation software, such as Simatic WinCC.
A range of diagnostic, logging and evaluation functions are also provided. For example, time stamps, fault profiles and result values can be archived in a database to generate trend analyses or statistics.
A primary use of this compact system is reading data matrix codes - such as direct part marks (DPMs) - on objects, under the difficult ambient conditions often found in industrial environments. Flexible lighting options enable the system to be adapted to specific applications. Typical uses include product tracing, process control and checking the quality of markings used in a variety of applications in the automotive, packaging, pharmaceuticals, cosmetics, electronics and food and beverage industries.
