Event List Columns

Each column in the event list represents an automatic measurement. This document describes each column present. Different decoders support different automatic measurements. Clicking on any automatic measurement will change zoom view to the time that measurement was made.

Table 1 - General Columns

NameDescriptionNotes

TStart

Start time of the event. The icon signifies the channel and if there are any warnings or errors in this event.

TWidth

The width of the event in time.

T-IFS

The time since the last event.

Use for testing diagnostic response messaging which requires specific delays.

ErCnt

Indicates how many errors this event has

Use with filter to quickly find events that have errors

WrnCnt

Indicates how many warnings this event has

ID

Node

Name of the node sending this event (requires a data base)

When enabled with a data base this enables statistical node analysis on automatic measurements.

Data

shows the data for the event

Table 2 - FlexRay Columns

NameDescriptionNotes

Res

The FlexRay reserved bit

PPI

Payload preamble indicator bit

Null

Null frame bit

Sync

sync frame bit

Start

startup frame bit

Ch

the flexray channel a or b

H-CRC

the header crc

CycCount

the current cycle count

CRC

the CRC - will be different for channel a and b

TSS (bits)

transmission start sequence measurement in bits

Dyn

indicates whether this is a dynamic frame

Len

Length of the data section in words

Table 3 - CAN Columns

NameDescriptionNotes

RTR

Remote transmit request bit

IDE

Identifier extension bit

RB0

reserve bit 0

RB1

reserve bit 1

HiV (SWCAN ONLY)

For single wire can this indicates the transmitter of the message is using the transceiver's High voltage mode

HiAck (SWCAN ONLY)

For single wire can this indicates the ack bit is high voltage meaning at least one receiver is using the high voltage mode of the transceiver

HiSpd (SWCAN only)

for single wire can this indicate the a high speed transition has occurred and is operating at the high bit rate

SRR

Standard frame remote request bit

Len

Length of data frame in bytes

CRCDel

The CRC Delimiter space

Ack

The acknowledgement bit

AckDel

the acknowledgement delimiter bit

CRC

The 15 bit CRC checksum

Stuffs

how many stuff bits are present in the CAN message

BitTol

The bit tolerance. The bits controlled only by the transmitter are measured between two recessive to dominant edges. This time is compared with the ideal bit time.

MinV

Here a minimum voltage is measured across the bits controlled by the transmitter (after the ID and before the Ack bit)

MaxV

Here a maximum voltage is measured across the bits controlled by the transmitter (after the ID and before the Ack bit)

AckSkew

The measures the time difference between the ideal starting ack position and the actual one

AckWidth

This measures the width of the ack bit

DataPercent

This measures the payload percentage of the message. This is how much data was sent compared to how long the entire frame requires.

Table 4 - LIN Columns

NameDescriptionNotes

Brk(bits)

Length of sync break in bits

Sync

value of the sync byte

TSlvRsp

Time between the master header and the slave response

THeader

Length of the master header in time

TResponse

Length of the entire slave response

TMaxUtil

This the length of the frame compared to the ideal length * 40% allowed by the LIN specification

Len

This is the length of the frames data section.

ChkSum

This is the checksum of the LIN message. Both standard and enhanced are calculated.

Table 5 - J1850 VPW Columns

NameDescriptionNotes

SOF

The length of the start of frame symbol in time

Len

the length of the message in bytes

CRC

The CRC check sum

IFR

In-frame response data (chrysler implementation only)

Table 6 - UART Columns

NameDescriptionNotes

Brk(bits)

the number of bits of a UART break if present

Len

the length of the data section

Data (ASCII)

The data section represented as ascii characters

Table 6 - I2C Columns

NameDescriptionNotes

AddrLen

The length of the I2C address either 7 or 10 bits

R/W

This indicates if it is an I2C write or read

Address

This is the address of the message

Len

This is the length of the data
