Note: The number of channels is configuration-specific. It is saved in the configuration
file and is restored when loading the configuration.
2.4.2 Channels in Online Mode
In Online mode with a real bus (menu item Configure│Simulation...) messages
from the simulation setup are transmitted on one or more real buses, and in the
measurement setup they are received by one or more real buses. The defined channels
correspond to these real buses with their controllers.
If you specify more than 2 CAN channels the following conditions must be satisfied to
be able to start a measurement:
• Your active CAN driver must support more than 2 CAN channels. If this is not
the case, you will receive a warning if you specify more than 2 CAN channels.
• A real or virtual CAN controller must be assigned to each channel. If this is not
the case, you will be requested to make such an assignment.
In the Channel Definition Dialog you can choose whether or not a consistency check
should be performed after configuration. The consistency check covers database assignments
and the configuration of all function blocks with the exception of CAPL
blocks. The check monitors whether invalid channels are referenced. If this is the
case an inconsistency is reported. These reports can be output to the Write window if
desired.
With CAPL blocks a determination of whether all referenced channels are valid is not
made until compilation. A warning is output if any channels are invalid. Therefore, it is
advisable to recompile all nodes after each new definition of channels.
If you use undefined channels, CANoe behaves as follows in Online mode:
• Channel configuration does not cause any filtering of messages in the data flow
plan.
• When receiving on controllers not assigned to a defined channel, the received
messages are passed through the measurement setup.
• When transmitting from a Generator block or Replay block in the measurement
setup to an undefined channel, the transmit request is similarly passed through.
• An error is reported in the Write window for a sender in the simulation setup as
soon as the transmit request is given to an undefined channel. The message is
not transmitted.
• CAPL blocks do not transmit messages to which an undefined channel is assigned.
2.4.3 Channels in Simulation Mode
In CANoe's Simulation mode (Online mode, Simulated bus option in the menu Configure│Simulation...)
buses and network nodes are fully simulated.
Each channel corresponds to a simulated bus. Set up your channel definition according
to how many buses you wish to simulate.
If you use channels that are not defined, CANoe behaves as follows in Simulation
mode:
