‘Extras’ ‘Trace Configuration’

With this command you will be given the dialog box for entering the variables to be traced, as well as diverse trace parameters for the Sampling Trace. The dialog can also be opened by a double click in the grey area of the dialog Sampling Trace.

First define a name for the trace configuration (Trace Name). This name will be added to the selection list ‘Trace’ in the upper right corner of the Trace window, as soon as you have confirmed and closed the configuration dialog with OK. Optionally enter a comment.

The list of the Variables to be traced is initially empty. In order to append a variable the variable must be entered in the field under the list. Following this, you can use the Add button or the Enter to append the variable to the list. You can also use the Input Assistant ( ‘Edit’ ‘Input Assistant’). The use of enumeration variables is possible.

A variable is deleted from the list when you select the variable and then press the Delete button.

A Boolean or analogue variable (also an enumeration variables) can be entered into the field Trigger Variable. The input assistance can be used here. The trigger variable describes the termination condition of the trace.

In Trigger Level you enter the level of an analogue trigger variable at which the trigger event occurs. You also can use an ENUM constant here. When Triggeredgepositive is selected the trigger event occurs after an ascending edge of the Boolean trigger variable or when an analogue variable has passed through the trigger level from below to above. Negative causes triggering after a descending edge or when an analogue variable went from above to below. Both causes triggering for both descending and ascending edges or by a positive or negative pass, whereas none does not initiate a triggering event at all.

Trigger Position is used to set the percentage of the measured value which will be recorded before the trigger event occurs. If, for example, you enter 25 here then 25% of the measured values are shown before the triggering event and 75% afterwards and then the trace is terminated.

The field Sample Rate is used set the time period between two recordings in milliseconds resp., if supported by the target system, in microseconds. The default value “0” means one scanning procedure per cycle.

Select the mode for recalling the recorded values: With Single the Number of the defined samples are displayed one time. With Continuous the reading of the recording of the defined number of measured values is initiated anew each time. If, for example, you enter the number ‘35’ the first display contains the first measured values 1 to 35 and the recording of the next 35 measured values (36-70) will then be automatically read, etc.Manual selection is used to read the trace recordings specifically with ‘Extras’ ‘Read Trace’.

The recall mode functions independently of whether a trigger variable is set or not. If no trigger variable is set the trace buffer will be filled with the defined number of measured values and the buffer contents will be read and displayed on recall.

Save is used to store the trace configuration which has been created in a file. The standard window “File save as” is opened for this purpose.

Stored trace configurations can be retrieved using Load. The standard window “File open” is opened for this purpose.

Note

Save and Load in the configuration dialog only relates to the configuration, not to the values of a trace recording (in contrast to the menu commands ‘Save Values’ and ‘Load Values’).

If the field Trigger Variable is empty, the trace recording will run endlessly and can be stopped by ‘Extras’ ‘Stop Trace’.
