CANoe DENoe - KEMT FEI TUKE

• The channel configuration does not cause any filtering of messages in the data
flow plan.
• When transmitting from a Generator block or Replay block in the measurement
setup to an undefined channel, the messages are passed through.
• When transmitting from a Generator block or Replay block in the simulation
setup to an undefined channel, an error is reported in the Write window as soon
as the transmit request is given to the undefined channel. Afterwards, the message
is not transmitted.
• CAPL blocks do not transmit messages to which an undefined channel is assigned.
2.4.4 Channels in Offline Mode
In Offline mode the channels correspond to those channels on which the played-in
messages were logged.
Consequently, each message is played-in on the channel on which it was logged.
The channels in Offline mode correspond to the channels used during logging to the
log file. Therefore, you should define the number of channels such that it corresponds
to the number of channels that were configured for logging to the log file.
If you use undefined channels CANoe behaves as follows in Offline mode:
• The channel configuration does not cause any filtering of messages in the data
flow plan.
• If messages are played-in which are assigned to an undefined channel, these
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 passed through.
• CAPL blocks do not send out messages to which no defined channel is allocated.
2.5 CANoe in Load and Overload Operation
This chapter helps you to operate CANoe steady under more difficult conditions and
points out the limits under high- and overload behavior.
2.5.1 Behavior in Load Situations
At high bus loading the computing power of your PC may be insufficient - under some
circumstances - to simultaneously operate the more complex evaluation and display
functions (Statistics window with statistical report, Data and Graphic window with
many signals, Trace window in the chronological output mode, etc.). To prevent an
impending data loss the program therefore has mechanisms for detecting and handling
load situations.
If the rate of messages registered by the card is so high that CANoe cannot follow
along with processing any longer, the ring buffer between the real-time library and the
CANoe- application runs full. CANoe detects this when a High water mark limit is
exceeded (cf. Figure 41), and it automatically switches over to a load mode in which
