Compare and Replace Measurement File Channels

Offline Evaluation of MDF-Files

� As soon as you add a second MDF file to a window, CANape offers the function [Compare signals with existing signals] in the context menu.

� CANape will automatically create common axes.

Possibility 2: Functions Overview

Offline Evaluation of MDF-Files

� Load

� Load a selected measurement file into the Symbol Explorer

� Display

� Display the selected file channels of a MDF file in a graphic window

� Replace

� Replace an already loaded measurement file with another file.

Load Measurement File Sequences

Offline Evaluation of MDF-Files

� CANape detects when a MDF–file belongs to a series of measurement files from the same measurement.

� [Always Load as Measurement] loads automatically all files from the measurement.

Exporting and Importing Measurement Data

Offline Evaluation of MDF-Files

� The measurement files can be exported into different formats automatically using [Analysis | Measurement files | Export options]:

� In order to evaluate measurement data in other formats the menu [Analysis | Measurement files | Import options] offers various converters:

Motivation

Data Mining with Algebraic condition

� Methods overview

� Function (library)

> MaxValue >= 100

� Matlab/Simulink model

> Complex algorithm

� Algebraic condition

> Signal1 >=90 && Signal2==1

� Script

� Mathematical methods provide a systematic analysis of large amounts of measurement files.

� Different measurement file formats are possible (MDF,DAT,BLF…)

� A report file provides you with hits to analyze.

Checklist for the Data Mining Analysis

Data Mining with Algebraic condition

1. Preparation of the CANape configuration

a. Use just one file to visualize the file channels to be analyzed

2. Configuration of the Data Mining analysis

a. Definition of the file filter list

b. Definition of the method(s)

c. Configuration of the options

3. Evaluation of the report file

a. Sighting of the hits navigated over the Symbol Explorer or the Data Mining GUI

14/18

Step 2a of the Checklist

Data Mining with Algebraic condition

� Definition of the file filter list

� Whole directories

� Single files (different formats)

15/18

Step 2b: Algebraic Condition as Method

Data Mining with Algebraic condition

� Definition of the method

� Enter the algebraic condition with a “pocket calculator “

Syntax Check

Functions for Online Use Cases

function Add(double A,double B ){

return A+B; }

function AverageValue3(double signal)

{

return ((signal[-2]+signal[-1]+signal)/3);

}

function Add ( A, B ){

return A+B; }

� Device-spanning assignment of measurement and calibration variables

� Processing of values from history (buffer) using brackets

� Graphic display of results using the return instruction

� Useful function calls/measurement modes:

� on input

� on event
