• the tab entitled "Tappet table": table editor for the definition of tappets tracks.
Below a line showing the Track ID, preceded by the symbol , as much lines are
displayed as tappets are defined for this track. These lines are preceded with the
symbol and each contains the tappet events definitions. So the following table
columns are available: Track ID (identification number of the tappet track); X: the
associated master position; positive pass / negative pass: events defined for
passing the master position in positive or negative direction.
Abb. 308 Main Editor: Tappet table
Attributes of tappets of one track, that is of the same identification number, refer to
the same tappet bit, that is a variable of boolean type. By default, a cam has the
attributes "switch on" on positive pass and "switch off" on negative pass, so that the
boolean variable will be set to TRUE on positive pass and set to FALSE on negative pass.
The event "invert" will negate the value of the boolean variable, whereas "none" has no
impact at all.
To add a tappet within an already existing track click on the symbol preceding the
track ID. A new row will be inserted beyond with master position 0 and default pass
attributes.
To modify a table entry you select it by a click. Afterwards you may either type a new
Track ID or master position or chose the attribute from the selection provided upon a
further click into the positive/negative pass field.
To delete a tappet click on the symbol that precedes the table row belonging to this
point.
To add a new track click on the symbol of the last table row. The two new rows will
be inserted, the first containing a track number not yet allocated, the second already
providing a default tappet with master position 0 and default pass attributes. A track
itself is deleted as soon as all of its tappets have been removed.
Editing within the element properties editor
The properties of an element currently selected in a graphical editor for a CAM or
tappet, can be displayed and edited in the "Properties" window, which by default is
available next to the toolbox window.
