CAN GW Analysis Function

When multi-channel log integration is used, GW Analyze becomes available.
GW Analyze provides the following CAN gateway analysis functions:

• Gateway latency analysis (GW Latency Analyze)
• Message loss analysis (Msg. Lost Analyze)
• Gateway residence analysis (GW Msg. Residence Peak Analyze)

GW Analyze Tab Display​

No.	Item	Description
[1]	GW CAN Frame List	Displays list of frames to analyze. Analysis can be enabled/disabled with checkboxes.
[2]	GW Information	Registers frames for analysis.
	From	Sets source channel of GW.
	To	Sets destination channel of GW.
	Ch dropdown	Sets target channel to analyze.
	CAN / CAN-FD	Selects CAN/CAN FD frame type.
	Std. / Ext.	Selects standard ID (Std.) / extended ID (Ext.).
	CAN ID input	Inputs CAN ID (Hex).
		Registers GW frame configured in GW Information to GW CAN Frame List. Up to 64 frames can be registered.
		Updates selected GW CAN Frame List frame with settings in GW Information.
		Deletes selected frame from GW CAN Frame List.
-	GW Latency & Msg. Lost Analyze button	Executes gateway latency and message loss analysis and displays result.
-	GW Msg. Residence Peak Analyze button	Executes gateway residence analysis and displays result.
-	Clear button	Deletes all target frames from GW CAN Frame List.

GW Analyze Setup Procedure​

1. Open GW Analyze tab
   Select GW Analyze tab in Analyze view.

2. Set target frames for analysis
   Set frame information in GW Information.
   Set source CAN ID in From and destination CAN ID in To.
   Click to register the frame in GW CAN Frame List.

3. Execute gateway latency/message loss analysis
   Click GW Latency & Msg. Lost Analyze to open Analyze Result window and display analysis results.

4. Execute gateway residence analysis
   Click GW Msg. Residence Peak Analyze to open Analyze Result window and display analysis results.

Gateway Latency / Message Loss Analysis Screen Description​

When GW Latency & Msg. Lost Analyze is executed, analysis results are shown in Analyze Result.

No.	Item	Description
[1]	From	Displays GW source channel.
	Protocol	Displays frame type (CAN/CAN FD) at GW source.
	ID	Displays standard/extended ID and CAN ID at GW source.
	To	Displays GW destination channel.
	Protocol	Displays frame type (CAN/CAN FD) at GW destination.
	ID	Displays standard/extended ID and CAN ID at GW destination.
	Max(ms)	Displays maximum latency.
	Max TimeStamp (note1)	Displays timestamp where maximum latency occurred.
	Min(ms)	Displays minimum latency.
	Min TimeStamp (note1)	Displays timestamp where minimum latency occurred.
	Ave(ms)	Displays average latency.
	Recv.Ave(ms)	Displays average GW receive cycle.
	Max Delay Rate	Displays maximum delay rate (max latency / average GW receive cycle) (note2).
	Sample	Displays sample count of same CAN ID.
	Lost Time (note1)	Displays first timestamp where message loss occurred.
[2]	Target Log tab	Displays logs to analyze.
	Gateway Analyze tab	Displays analysis result.
-	Save button	Saves displayed Gateway Latency Analyze Result as CSV.
-	Close button	Closes Analyze Result window.

note1: Double-clicking a timestamp item opens Target Log tab and shows corresponding log.
note2: If loss occurs, latency result values (Max/Min/Ave/Recv.Ave/Max Delay Rate/Sample) are calculated from data up to first loss occurrence.

Gateway Residence Analysis Screen Description​

When GW Msg. Residence Peak Analyze is executed, analysis results are shown in Analyze Result.

No.	Item	Description

	Peak Time (note)	Displays timestamp where peak occurred.
	Sample	Displays sample count of GW frames.
	Save button	Saves Ch Result display as CSV.
[2]	Gateway Residence Analyze Result(Frame)	Displays gateway residence analysis result per GW frame.
	From	Displays GW source channel.
	Protocol	Displays frame type at GW source.
	ID	Displays standard/extended ID and CAN ID at GW source.
	To	Displays GW destination channel.
	Protocol	Displays frame type at GW destination.
	ID	Displays standard/extended ID and CAN ID at GW destination.
	Peak	Displays maximum retained frame count.
	Peak Time (note)	Displays timestamp where peak occurred.
	Sample	Displays sample count of same CAN ID.
