Integration

The main functions of SIMATIC MV440 are:

• Reading 1D and 2D codes
• Verification (required license "Veri-Genius")
• Text recognition (required license "Text-Genius")
• Object recognition (required license "Pat-Genius")
• Comparison of the read result with a default value
• Formatting the read result for forwarding

The functions can be used individually or they can be combined.

All functions, including all licenses, are available to the user in demo mode on each version of the MV440. It is therefore possible to test a licensed function at any time. However, the output result is unusable, because one or more characters of the result will be randomly replaced by the ‘?’ character. Binary results are completely suppressed.

Read

The SIMATIC MV440 reads the following 1D and 2D codes (detailed information can be found in the manual):

• 1D codes (barcodes):
  • Int. 2/5 (with/without checksum)
  • Code 128
  • Code 93
  • Code 39 (with/without checksum)
  • Code 32
  • EAN 13
  • EAN 8
  • UPC-A
  • UPC-E
  • CodaBar
  • GS1 DataBar (Omnidirectional, Stacked, Limited, Expanded)
  • Pharmacode (0° and 180°)
  • Postnet
• 2D codes:
  • Data Matrix Code (ECC 0 - 200)
  • PDF417 (without: Truncated, Micro and Macro)
  • QR (without: Micro and Macro)
  • DotCode
  • Vericode (demo mode/VeriCode license)

Verification

Verification is the term used for measuring the marking quality of 1D and 2D codes. This additional functionality is subject to license and is available for every SIMATIC MV440 by installing the "Veri-Genius license". The following verification methods are supported:

• ISO/IEC TR29158 (previously AIM DPM-1-2006)
• Siemens DPM
• ISO/IEC 15415
• AS9132 Rev. A (previously IAQG)
• ISO/IEC 15416 (previously ANSI X3.182-1990)

Optical character recognition

Text recognition is used to detect plain text (Optical Character Recognition: OCR). This additional functionality is subject to license and is available for every SIMATIC MV440 by installing the "Text-Genius license" or the "Text-Genius-Plus License".

Text recognition with the "Text-Genius license" is able to recognize many fonts without training immediately after installation. Particularly suitable fonts are:

• OCR-A
• Semifont M13
• and similar fonts

With the "Text-Genius Plus license", text recognition can be expanded to include numerous fonts, print image versions (e.g. distortions), and special characters. By contrast, this version requires training, but offers almost unlimited potential in expanding the range of characters to be recognized.

Object detection

Object recognition is used for finding and recognizing trained patterns in the picture. This functionality can be used alone or in combination with all other functions mentioned. Accordingly, it has different areas of application: Shape recognition offers the following functionality:

• Object recognition (classification)  
• Position detection (position, rotational position, scaling) 
• Presence check (object recognition and position check with setpoint specification)  
• Completeness check (multiple presence check with setpoint specification) 
• Text recognition (based on the contour of any character or symbol). However, shape recognition can also be used in combination with text recognition, for example. In this case, the text recognition read area can track the current position of an object or label.

Note: In demo mode, the full functionality of the devices is available. Testing of a licensed function is therefore possible at any time. However, the output result is unusable, because one or more characters of the result will be randomly replaced by the character '?'. Binary results are completely suppressed.
