Calibration and data acquisition tool

CAN FD support and other improvements

Accurate Technologies (ATI) has released the version 5.1 of its Vision calibration and data acquisition software. It offers several additional features including the support of CAN FD.

The recently introduced Vision version 5.1 comes with a CAN FD interface product developed by Kvaser, The tool is able to stream data directly to an Asam MDF 4.1 file when recording data. A key benefit of this enhancement is that users are able to record for longer periods of time and capture more data at higher data rates than before said the supplier. Another new feature is the Vision Model Based Calibration (MBC) toolkit). It brings advanced calibration and data acquisition features to control system designers working on model-in-the-loop (MIL) simulations. MBC can instrument a Simulink MIL system and makes it easy to control and calibrate in vision, stated ATI However, the MBC does not come by default with the tool, an additional license is required.

The CAN FD interfaces support ISO CAN FD as well as non-ISO CAN FD protocols. There is no additional hardware required to connect ECUs (electronic control units) to the provided tool.

Other new features include:

  • The LED control is available for displaying a maximum of three different colors, which illuminate to represent when the associated data value is below a preset threshold, between thresholds, or above a threshold.
  • The Datalist enhancements allow additional customization of the data view enabling easier data location without scrolling through the entire list.
  • The Dashboard speeds have been improved by reducing latency time for data items to update. As a result data displayed on remote Dashboard is more accurately presented.
  • Abort and Cancel buttons have been added for the rare situations where the recording of data in VISION doesn’t meet the desired expectations at the start.
  • Recorder Panel buttons are now auto scaled proportionally to the control size.
  • The Datalist allows modification of decimal point setting for all data items allowing Dashboard control theme to override the default decimal precision value as desired by the user.

Previously known as Vision Studio the next generation of ATI calibration, measurement, and development software has been renamed to Vision Tool Suite. Along with the name change there have been several alterations to the toolset that is now available in the suite. It provides several software plugins:

  • Data Analyzer (.REC and .MF4 files)
    Support for custom layouts (.layout) that can be applied to different recording files is now possible
  • A2L Explorer for Asam MCD-2 (ASAP2) files (.a2l files)
  • ATI VID Configuration Editor (.hcf files)
  • Automated Test Sequence (.ats files)

Important: All of the files above can be created or edited in by means of Vision Tool Suite except MF4 (MDF) Files. Therefore, the Data Analyzer only views files.

The Data Analyzer provides a platform for viewing MDF4 recorder files that are created by Vision. Measure Data Format files (MF4 or MDF4) may contain a huge number of measurement data items and typically include a notable number of related attribute data values. All of this information stored in the new recorder file format (MDF4) can result in sizeable files, which are viewable in the Data Analyzer tool.

In addition, the Data Analyzer is designed to provide capabilities that extend some of the features already available in the legacy Vision recorder file viewer. Enhanced versions of these features such as Recorder file overlay, Calculated Channels, etc. have been added into the Data Analyzer.

Definition of the data item’s traces, their attributes (colors, min/max ranges, etc.) and other settings may be stored into a Layout (.layout) file. The retention of these settings enables the view into the data analysis to be saved for later review by the original creator or others to which the file is shared.
