Log Replay Function

The log replay function can transmit log content exactly as recorded in this tool's log file format.
Up to 1.2 million records can be used as replay targets.

Product Usage Image​

By capturing communication logs between ECUs in advance, communication simulation by log replay is possible even without ECU:A.

Basic Operation​

1. Select Log Replay in Simulation Window
   Select "Simulation Window" from the menu or toolbar, and select "Log Replay" from "Simulation Mode".
   This enables the log replay function.

2. Specify target log file to load
   Click the "..." button for "Log File".
   A file dialog appears. Specify the MicroPeckerX log file to load.

3. Load log file
   Confirm that the path of the log file specified in step 2 is shown in "Log File", then click the load button.
   The data in the specified log file is loaded.

4. Start monitoring
   Start monitoring by one of the following operations.

• Select "Command" - "Start" from the menu bar.

• Click the button on the toolbar.
• Press the F5 key.
  Frames are transmitted based on the log file content loaded in step 3.

Log Replay Screen Description​

Item	Description	Notes
Log File	Displays full path of the target log file selected in file dialog from the button.	The target log file can also be set by directly entering full path.
Button	Click to display file dialog and select target log file to load.	The selected log file is not loaded until the button is clicked.
Button	Click to load the log file shown in "Log File".	MicroPecker log files cannot be loaded.
Loop	Sets whether log replay transmission repeats. Meanings of checkbox ON/OFF are: [ON] After transmitting the bottom log data in the list, returns to top and transmits log data sequentially again. [OFF] After transmitting the bottom log data in the list, transmission stops and enters waiting state.
First Delay	Sets time in milliseconds until transmission of the top log data in the log data list. Configurable range is "0 to 60000". If "None" is set for "Event Trigger", this is elapsed time from monitoring start. Otherwise, it is elapsed time from event detection.	When changed by spin button, value increases/decreases in 10 ms units.
Button	Click to open "LIN LogReplay Dir Stting" dialog and set type of transmission frame by ID. For details, see "LIN LogReplay Dir Stting".
Button	Click to stop log data transmission.	After transmission is stopped with this button, transmission cannot be resumed. To retransmit log data, you must stop monitoring once.
Log Data List (Area 1)	Displays log data included in loaded log file.	Records with the following Type are excluded from display target: Header, Bit Err., Nores. Err., H. Timeout, UART Err., Bus Err., B-Sleep Records with the following Type are displayed, but response becomes dummy value (00H for all bytes): Parity Err., SyncBrk. Long, SyncBrk. Short, SyncField Err. Delay value of each log data is the time difference from Time of the log data directly above it (microsecond part truncated). For the top log data only, Delay is set to the configured "First Delay" value.
Event Trigger	Sets whether to use event trigger and its occurrence condition. For details, see "Event Trigger".

LIN LogReplay Dir Setting​

You can set transmission frame type by ID.

Item Name	Description
Dir	Sets transmission frame type. Click "Tx" or "Rx" to change to that type.
Button	Click to save transmission frame type changes and close dialog.
Button	Click to discard transmission frame type changes and close dialog.

Event Trigger​

Sets whether to use event trigger and its occurrence condition.

Item	Description	Notes
None	Event trigger is not used.
Ext Trigger	Detects port input as event.	This feature is under development and cannot be used.
Log Trigger	Detects specified monitoring log as event.
Key Trigger	Detects specified key input as event.

Log Trigger Setting​

In Log Trigger, configured logs can be detected as events.
Various conditions such as specific data and errors can be set.

Log Trigger Screen Description​

Screen Menu	Description
Event Condition (Area 1)	Displays log information configured as event occurrence condition. Double-clicking this area opens "Trigger Setting" dialog and allows configuring log information for event condition.
Button	Click to open "Trigger Setting" dialog and configure log information for event condition.

For details of "Trigger Setting" dialog, see "Trigger Setting Dialog Screen Description".

Key Trigger​

In Key Trigger, key input from keyboard can be detected as events.
This enables operations such as transmitting frames by key input.

Item	Description	Notes
Main Key (Area 1)	Sets key used as trigger. Pull-down options are: None, A, B, ..., Z, 0, 1, ..., 9, F1, F2, ..., F12, SPACE	If "None" is set for main key, event detection by key input is disabled, so log data transmission is also disabled.
Sub Key (Area 2)	Sets sub key used together with main key as trigger. Pull-down options are: None, Alt, Ctrl, Shift Set "None" when not using sub key.	Event detection cannot be done with sub key only.
