Optical Identification Systems

Flexible reading and verification

Optical identification is the key to digitization and transparency – and ensures complete traceability of products and components along the entire manufacturing, procurement and shipping process. Siemens offers you a complete, scalable portfolio of high-performance and flexible optical readers – for both stationary and manual applications. They enable fast and easy reading and verification of 1D/2D codes, optical character recognition (OCR) and object recognition, and ensure reliable identification on a wide variety of surfaces even under difficult ambient conditions. An unbeatable plus: All devices can be easily integrated into the automation environment and offer a variety of options for communication and connection.

Optical codes

Codes and their fields of application

Four steps are required for complete traceability during production and beyond: Marking, Verification, Reading, Communication (MVRC). 

 

Marking is the application of the coding directly to the object.

Verification stands for checking the quality of markings on the object.

Reading is the reading in production or in case of service.

Communication includes the visualization and interpretation of the reading results. 

 

Whether 1D barcode, 2D data matrix code or text recognition via OCR: Each technology has its specific strengths. For example, plain text recognition is used where information must also be legible for people, such as the best-before date. Siemens offers you proven products and systems for all these areas.

2D data matrix code

Compared to the barcode, the 2D data matrix code offers a higher storage capacity, more data security and a better reading rate in terms of viewing angle and illumination. These codes can be applied cost-effectively, e.g. together with shipping labels. In addition, they enable direct part marking (DPM) of products by laser, printing or nailing, which makes them particularly robust against external influences and has proven its worth especially in harsh industrial environments.

Text recognition (OCR)

OCR licenses for SIMATIC MV440

The SIMATIC MV440 stationary readers can be used with the OCR licenses "Text-Genius" and "Text-Genius Plus" for text recognition. They also enable simultaneous reading and comparison of plain text and machine-readable codes in one image field. The licenses are delivered as "Single License" on USB flash medium and can be loaded on the device and on replacement devices via the SIMATIC Automation License Manager (ALM) with a plug-in.

The "Text-Genius" OCR license enables flexible reading of numerous fonts without time-consuming training. In different performance classes – and with flexibly selectable accessories and optional communication modules for connection to the automation system.

 

These fonts are particularly suitable:

  • OCR-A and OCR-B
  • Semifont M13
  • Arial and similar fonts
  • All characters of the ASCII character set

 

"Text-Genius" runs on SIMATIC MV440 as of firmware version 3.0.

"Text-Genius Plus" includes all the features of "Text-Genius", plus the ability to train additional fonts and characters, including special characters and graphical symbols – easily and self-explanatory with thumbnails. The convenient algorithm of "Text-Genius" minimizes the effort required for training. High-performing and intelligent, versatile in production and logistics – benefit from the bundled advantages of the compact MV series:

 

"Text-Genius Plus" runs on SIMATIC MV440 as of firmware version 5.0.

  • Flexible reading of numerous fonts without time-consuming training
  • Fast and secure reading (up to over 1,000 readings per minute) for high-speed applications

Object recognition

"Pat-Genius" license for SIMATIC MV440

With "Pat-Genius", SIMATIC MV440 can also be used for object and position detection. It can also be used to read 1D/2D codes or plain text. All functions for reading and comparing plain text and machine-readable codes can be freely combined in one image field. "Pat-Genius" is used with Pick&Place for quality control in production, position detection in feeding technology as well as quantity monitoring in feeding technology and production. The license is delivered as "Single License" on USB flash medium and can be loaded onto the device via the SIMATIC Automation License Manager (ALM) with a plug-in. The license runs on any SIMATIC MV440 as of firmware version 6.0.

Object recognition is used to search for and recognize trained patterns in the image:

  • Object recognition (classification)
  • Position detection (position, rotary position, scaling)
  • Presence verification (object recognition and position control with setpoint specification)
  • Completeness check (multiple presence verification with setpoint specification)
  • Symbol recognition (recognition of the contour of any character or symbol)
  • High scan rate of up to 2,500 scans per minute

  • Easy integration of the "object recognition" function into PC-based applications through TCP, HTTP commands and HTML output
Verification systems

Marking quality test with Veri-Genius

Contamination in the production process can impair markings. Only high-quality marking ensures maximum legibility even if the marking quality deteriorates due to scratches or dirt. With "Veri-Genius", SIMATIC MV440 can also be used to check the marking quality of codes. In addition, verification reduces production costs, since it reduces the requirements for material quality and marking technology. The license is delivered as "Single License" on USB flash medium and can be loaded onto the device via the SIMATIC Automation License Manager (ALM) with a plug-in. The license runs on SIMATIC MV440 as of firmware version 4.0.
  • Testing of marking quality according to a large number of internationally recognized test regulations, in particular ISO 29158
  • Different resolutions available (640 x 480 pixels, 1024 x 768 pixels and 1600 x 1200 pixels)
  • Simultaneous reading and verification in one image field
  • Simple integration of verification into the automation environment via the SIMATIC MV440 in PC-based applications and other automated production lines

"Veri-Genius" supports all major industries and code types through the following verification standards:
