1. Introduction

LoadMdf allows to load into Matlab WorkSpace acquisition data contained in .DAT or .MDF files in format 3.0 produced by ETAS INCA® tool or other program that support Bosch MDF (Measured Data Format) .

2. Launch of LoadMDF

For launch loadmdf there are various mode:

·Basic:

>> loadmdf

in this case a dialog box is open to choose MDF file

·Explicit:

>> loadmdf('acq.dat')

in this case the file name ('acq.dat' for this example) is previous selected and no query dialog is open.

·Extended:

>> loadmdf('acq.dat','label')

in this case the labels name with corresponding values of enumerative variables are loaded into workspace

·Debug:

>> loadmdf('acq.dat','q')

in this case a list of full internal name of variables is showed.

·Append:

>>loadmdf(‘acq.dat’,’append’,’_acq’)

In this case a string (‘_acq’ in this example)is appended in all variables names saved in workspace .

For example RPM becomes RPM_acq

It’s possible to use all parameters together for example:

>> loadmdf(‘acq.dat’,’label’,’append’,’_acq’)

In this case two extra actions are activated: creation of label into workspace and appending of‘_acq’ in the variables name.

2.1. Structure Format of Variables Loaded

All variables loaded in workspace are structured data with various fields, in the following examples are reported.

rpmf

Data: [3599x1 double]

Type: 'variable'

Time: [3599x1 double]

Description: 'Eng. Speed proc. - Filtered engine speed'

Unit_measure: 'rpm'

Sampling_Time: 0.0050

FAULT_GLOW_ACT1

             Data: [899x1 double]
             State: {6x2 cell}
             Type: 'state'
             Time: [899x1 double]
             Description: 'Vector Fault Type for Feedback Diag'
             Unit_measure: [1x0 char]
             Sampling_Time: 0.0200

For this state variable is present a field State in the following form:

>> FAULT_GLOW_ACT1.State

ans =

    'BCA_NO_FAULT'             [ 0]
    'BCA_GEN_FAULT'           [ 1]
    'BCA_VAR_TOO_HIGH'    [ 2]
    'BCA_NO_SIGNAL'           [ 3]
    'BCA_OPEN_LOAD'          [ 4]
    'BCA_NOT_PERF'              [255]
