Integration in the Tool Chain

CANdb++ is a central tool in the Vector CAN tools toolbox, and it can be started directly from Vector CAN tools

such as CANalyzer, CANoe, CANape and CANscope. This provides the Vector CAN tools with direct access to

communication-relevant data via CANdb++.

Communication-relevant data are defined, modified and managed entirely within CANdb++; the Vector CAN

tools only read-access these data. The communication-relevant data must exist in the form of CANdb network

files (*.dbc) so that the Vector CAN tools can access them.

To also permit the use of data from CANdb++ databases (*.mdc) CANdb++ provides a data export option.

CANdb++ databases can be exported to one or more CANdb network files (*.dbc). In this way the user can either

export the data of an entire CANdb++ database or only those relevant to a Vehicle, Network or ECU.

The subordinate structure level is then shown.

For example, if you wish to link a signal to a message click the symbol to the left of the

Messages object type.

CANdb++ Manual 3Tutorial

2. Open a List Window for the object type of the object you wish to link.

To do this, choose the View|List… command for the relevant object type.

For example, if you wish to link a signal to a message choose the List-Signals command to

open a List Window with signals.

If necessary change the size of the Overview Window and the List Window so that the relevant

areas are visible in both windows.

3. In the List Window select the object that you wish to link.

4. Link the two objects.

To do this, drag the selected object from the List Window to the Overview Window while holding

down the mouse button. Do not release the mouse button until the mouse pointer is located

above the object in the Overview Window with which the link is to be made.

The shape of the mouse pointer indicates whether the objects can be linked or not.

The link is automatically added after releasing the mouse button.

The linked object appears in the Overview Window below the object with which it was linked.

The object symbol of the linked object changes to display the link.

For example, the object symbol of a linked signal, i.e. a message signal would appear as .

As an alternative to this you could link objects by menu commands as described below:

the system attribute cycle time. In the default setting, therefore, the system attribute cycle time of a message

(e.g. on the "Message - Definition" page) cannot be processed directly; instead, it is determined via the user-

defined attribute.

GenMsgSendType

Describes the transmitter type of the message or the relation node-Tx message. The available values are user or

OEM-specific. With the default settings in CANdb++ ("PropsFromUserAttrs=1" and "AttrMs-

gSendType=GenMsgSendType" in CANdb.ini) this value is mapped to the system attribute transmitter type (Tx

method). In the default setting, therefore, the system attribute transmitter type of a message (e.g. on the "Mes-

sage - Definition" page) cannot be processed directly; instead, it is determined via the user-defined attribute.

GenSigInactiveValue

Describes the value of a signal for which the signal is in the inactive state. Signals that are sent with the trans-

NmStationAddress

A node that uses the OSEK NM (network management) must have a NM-ID that is unambiguous on the network

(within a vehicle, the NM-ID does not have to be unambiguous). This NM-ID is managed in the attribute NMSta-

tionAdress. In the CANdb++ default setting("PropsFromUserAttrs=1" and "AttrBusType=NMStationAddress" in

CANdb.ini), this value is mapped to the system attribute 'address' of a node.
