block which is initially connected to the simulated bus, i.e. the bus with the red line.
The function block contains two text lines. The upper line shows the name of the
node and is initially empty for a newly inserted node. The status bar below it provides
information on node status and node type.
The configuration dialog for a network node can be opened by right clicking on the
network node and choosing Configure from the popup menu. The corresponding
node name can be selected from those defined in the database; if no name is selected
the name will remain >.
With the [File...] button you can open a file selection dialog. Here you can select the
CAPL program which describes the functionality of the network node. The [Edit] button
opens the CAPL Browser with which you can create the selected CAPL program
or edit it later in a user-friendly manner. All CAPL programs must be compiled before
the measurement start. This is done by activating the [Compile] button or by selecting
the menu command Configuration│Compile all nodes.
The node status option buttons can influence the function of a node. The status real
indicates a node on a real bus. It is shown in the simulation setup by a black connecting
line to the actual bus and is designated as real in its status line. In this case the
network node model has no influence on the measurement.
Simulated nodes are represented as red connection lines to the simulated bus. During
a measurement its functionality is simulated by an assigned CAPL program. The
bus behavior of the network node does not differ from that of a real controller with the
same functionality.
Individual network nodes can be switched-off intentionally with the options button off.
This breaks the connection to the bus. 5
The user simply presses the spacebar to toggle the status of the currently active
node in the simulation setup. The node status changes with each spacebar press
from simulated to real to off and back to simulated.
The menu item Start delay can influence the behavior of the network node before
the start of the measurement. The button switches this influence to active, which
causes the node to remain inactive for the set time period after the start of the measurement.
Messages are neither sent nor received during this time, nor do they react
to external conditions such as environment variables or key presses.
This delay can also be defined as a supplemental attribute in the database and activated
via the corresponding checkbox.
The simulated network node timers can also be influenced by Drift and Jitter. When
this is the case, the user can toggle between fixed deviation and an equally distributed
fluctuation. With fixed deviation the value can be given in per cent, and all timers
for this network node will expire a bit faster or slower around this value. With uniform
distribution, on the other hand, an interval can be entered from which the fluctuations
of each timer is purely chosen.
These values can also be defined as supplemental attributes and activated from
CANdb++.
5 In Version 1.0 this has the same effect as the option real.
