CANoe DENoe - KEMT FEI TUKE

The search sequence in the database list in the database selection dialog is also
used to resolve name conflicts when configuring measurement windows and function
blocks. In such a case, the name is associated with the message in the database that
is highest in the list. However, you can also resolve ambiguities of this type by qualifying
symbolic names.
See CANoe's online Help function for examples of resolving ambiguities.
2.3.6 Checking for Consistency of Symbolic Data
In CANoe's symbolic mode the CAN messages are addressed using symbolic names
from an associated database. Therefore, CANoe checks the consistency of the database
and the active configuration in the following situations:
• At the program start,
• When a new database is associated,
• When CANoe is restarted after a change to the database.
In this consistency check, the symbolic names of all CAN messages used in the
measurement and simulation setups are compared to names in the database. If the
message name has been changed in the database, an automatic adaptation is made
to this name, and an appropriate message appears on the screen. If CANoe could
find neither the name nor the message ID in the database, the user receives an error
message. In this case the measurement cannot be started until the particular message
is removed from the configuration.
2.4 Working with Multiple Channels
CANoe supports up to 32 (virtual and real) CAN channels. Consequently, you can
also use multiple CAN cards to transmit and receive messages. This section describes
what must be taken into consideration when working with multiple channels.
2.4.1 Channel Definition
The number of CAN channels you wish to use is configured in the Channel Definition
Dialog.
You can access this dialog from the main menu item Configure│CAN channels... on
the menu bar or from the PC card icon in the measurement setup. In addition to affecting
the measurement itself, the channel definition also affects the inputs that are
possible in the various configuration dialogs. Only defined channels are offered for
selection.
The channels are allocated to the CAN chips registered in the CAN hardware configuration
of your computer's Control Panel. Chip allocation is only meaningful in
Online mode. In Offline mode, in which messages are replayed from a file, it is irrelevant.
To change the default chip allocation, open the CAN Hardware component of your
computer's Control Panel. The CAN Hardware Configuration Dialog appears, in
which you can modify the chip allocations of the channels.
The chip allocation is also shown in the Hardware Configuration Dialog (cf. section
2.11.1).
