Pat-Genius for MV440 Siemens

Область применения

The functionality of object recognition is basically suitable for applications such as      

• Pick-and-place machines
• Quality control in production
• Position detection in infeed systems
• Quantity monitoring in infeed systems and production

Pat-Genius can be used anywhere where ambient conditions permit the use of the optical MV440 reader - for details, see SIMATIC MV440. Standard ring lights and lenses are available for IP67 degree of protection by means of the protective barrel, and for glass-free use in the food and beverages industry. If light sources or lenses are used outside the protective barrel, they must be used in compliance with their specification.

Any host and HMI systems required must be selected for a sector and a specific project. The range of application of the selected test method is defined in the specification of the test method and compliance is essential if universally valid results are to be obtained.

The following sectors and applications are a particular focus for MV440 verification systems:

Automotive industry

For example:

• testing the manufacturing process: e.g. assembling the body in white, etc.        
• Access control for semi-finished products for machining stations in the process: Cylinder heads, etc.        
• Monitoring the uniformity of the assembly quality in the manufacturing process

Pharmaceutical industry  

For example:

• Checking of warning information on medicines (e.g. Caution poisonous)
• Checking of the correct arrangement of the content and the closing mechanism in the packaging process·                    
• Checking the filling level of packages 

Medical equipment  

For example:

•  Inline quality check and documentation by means of checking completeness and shape consistency

Electronics

For example:       

•  Inline quality check and documentation by means of checking completeness and shape consistency

Semiconductors

For example:

• Detecting the alignment of components
• Controlling the dimensional accuracy of components

Object recognition with Pat-Genius

With the object recognition license "Pat-Genius", devices of the SIMATIC MV440 family can also be used for checking the specifiable structures in the image (verification) in addition to reading 1D barcodes and 2D matrix codes.

The license is supplied as a "Single License" on a USB flash drive and can be installed via the SIMATIC Automation License Manager (ALM) on any reader of the SIMATIC MV440 series. The license can be installed on a SIMATIC MV440 as of firmware version 6.0.

Функции

The object recognition detects deviations in the current camera image relative to a learned structure using edge structures.  

Accordingly, the basic test sequence is as follows:

• Training the object test parameters using one or more good objects
• Testing an object and/or pattern with the features taken from the training
• Testing can be performed on stationary and moving objects
• Checking for a match with the reference provides a good/poor indication after comparison with set-value criteria
• Test results output to three control outputs:
  • OK:  Presence of the trained objects and/or pattern recognized by characteristics
  • OK: Level of agreement greater than setpoint
  • ...
  • N_OK: NO presence of trained objects with the specified characteristics
  • N_OK: Deviation from degree of conformity to setpoint
  • ...
• Output of the result information onboard via PROFINET IO, Ethernet, RS232 interface – further interfaces are available via communication modules
• "Stand-alone" mode possible using integrated DI/O
• Remote control via PROFIBUS IO, PROFINET DP (via communication module), DI/O or Ethernet
• Platform-independent, web-based interface (Internet-enabled):
  • Monitoring (live image in read mode)
  • Diagnostics (fault image, log information, ...)
  • System administration (software update, ...)
  • Error analysis for troubleshooting for faulty readings
• Triggering of external ring lights  

The overall result and the components of a measurement result can be output after a test via different interfaces, and are then available for further processing on an external system, e.g. for archiving or creating a test report.

Интеграция

Pat-Genius for SIMATIC MV440 can use all communication services that the SIMATIC MV440 basic unit offers:

The most important types of interface in the automation environment are shown in the overview below. For further details, refer to the chapter on SIMATIC MV440.

Особенности

• Pat-Genius shape recognition contains the following different partial tasks:
  • 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)
• Pat-Genius is easy to operate thanks to its integration in the uniform operating concept for all function packages in the user interface of the MV440 devices
• Pat-Genius can be used together with all other function packages (Text-Genius and Veri-Genius) of the SIMATIC MV440 devices.
• Pat-Genius is available for all resolution versions of the SIMATIC MV440 (640 x 480 pixels, 1024 x 768 pixels and 1600 x 1200 pixels).
• Pat-Genius can be flexibly retrofitted for every device of the SIMATIC MV440 family (via the SIMATIC Automation License Manager). Customer benefit: Cost benefits with stocking spare parts.
• Pat-Genius licenses are transferrable between all SIMATIC MV440 devices without regard for the resolution capacity.
• Pat-Genius supports the proved simple integration of the SIMATIC MV440 devices into the automation environment using a function block (FB79, FB45 and FB101) for the SIMATIC S7-1200, S7-1500, S7-300 and S7-400 controllers.
