New 1D/2D Code Reader from Siemens Delivers Speed and Reliability
“One of our goals at Siemens is to simplify life on the shop floor and to continually enhance integration of all intelligent aspects of the process,” says Ed Housler, Siemens spokesperson. “The new compact MV420 Code Reader is another step in Industrial Identification, and part of Siemens Totally Integrated Automation Platform.”
1D/2D Code Reading Systems have quickly become a must-have technology for state of the art production systems in a number of industries. For markets like pharmaceuticals and food and beverage Code Reading provides an easy means of providing legally-mandated product traceability. In other industries, like automotive, electronics and packaging, direct machine readable identification systems have seen widespread adoption for improving efficiency and quality. By employing unique coding symbologies, managers and engineers are able to plan each and every step of production for every part manufactured while managing and tracking changes within the production process and in the materials used.
The new compact SIMATIC MV420 stationary 1D/2D Code Reader from the Siemens Industry delivers a high level of reliability and installation flexibility through a wide range of communications and connection options.
“One of the traditional problems with 1D/2D codes in general is reading the code correctly in adverse conditions,” says Housler. “This is a particular strong suit of the MV420 which can read both standard high-contrast codes as well as direct parts marking codes even in poor lighting conditions without compromising line speed.”
Other features and improvements over other 1D/2D Code Readers include:
- Compact design with IP67 degree of protection
- High reading speed of up to 40 codes per second
- Auto triggering
- Multi code reading
- Interfaces: PROFIBUS DP (via ASM Module), PROFINET IO, Ethernet and RS232
- Simultaneous combined operation of RFID readers and MV420 Code Reading in a single communications module
The SIMATIC MV420 has integrated lens and lighting, and boasts a one to 22.5 centimeter adjustable operating distance using an integrated focus making it highly flexible on the shop floor, says Housler. “And it’s fast enough to process 50 codes per second. Thanks to the multi-code reading capability several codes and even different code types of codes can be decoded from a single image which is really useful when bulk-reading stacked items.
“Auto trigger is particularly cool. This is a recoding mode that 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.”
The integration aspect comes from the built-in PROFINET IO, Industrial Ethernet TCP/IP, and RS232 interfaces which essentially make it plug and play. PROFIBUS DP can be connected via a communications module, which also allows mixed operation with RFID systems. For most applications parameters come preset, but any commissioning that is required is done through a built-in Web server using Internet Explorer. No additional software is required.
“The Web-based user interface gives extensive operator configuration, control and monitoring functions that are really easy to use. It’s all about ease of use and simple integration of what has become a critical automation process,” concludes Housler.
