Log Replay

Added from the Source dropdown menu, the Log Replay can be used to replay a previously saved CAN log file. This feature supports all of the file formats the Message Logger is capable of creating, making for a convenient way to replay previous logs recorded with CanKing.

Once a log file has been selected, the Transceiver Mode can be set to replay the Rx messages, Tx messages, or both simultaneously with a toggle to set whether or not error frames should be included in the transmission. By default, Log Replay is set to replay the log file once. This can be altered by adjusting the value in File Iterations which lists how many times a file should be played. Should an indefinite loop of the log file be desired, the value can be set to “-1”.

To change the Sample Rate, set the message to the desired duration in milliseconds.  If the value is left at “0”, the timestamps from the log file will be used to simulate the original transmission’s cadence. When the Log Replay begins transmitting it is  dependent on the radial options just below Message Sample Rate. Transmission can begin immediately, at the timestamp of the first message in the log file, or after a manual offset measured in milliseconds.

For Log Replay to transmit on the bus, there must be a channel available in Sources that can be assigned to be the node from which each channel in the log file can transmit from. Set the node for each channel you wish to replay, leaving unassigned any channels that you want to omit.

Finally, the replay speed can be further altered by adjusting the Time Factor. A value set by percentage that can increase or decrease the time between messages replayed from the log. The Lower and Higher Variances can be set to fine tune replay speed by creating a range of acceptable timings between sending messages from the log.
