LIN No Header & LIN Header only No Data

[itsnewforme]

Hi, I'm using NXP Lin stack for S12ZVML64 as Slave.

I want to ask few things about LIN No Header & LIN Header only No Data.

1. I'm having my ECU in running mode but I'm not transmitting any Header from CANoe. In such case how can I show this on CANoe

2. I'm only transmitting Header and no Data from CANoe in such case how does the Slave responds to it and how can I show this on CANoe.

Thanks in advance

Abhijit.

Thank you so much @nxf78987 . I just want to confirm one thing. 

When we say that we are sending only header from CANoe with no Response. Is that simply means that our ECU(Slave) is off and only CANoe is running. Because  as per the understanding the Master(CANoe) sends the header and Response is either sent by Master or Slave.

Thanks you so much once again for helping with the canoe_test.zip

Hi itsnewforme,

1. When we say that we are sending only header from CANoe with no Response. Is that simply means that our ECU(Slave) is off and only CANoe is running?

=> This means is Slaves existed on the bus and no response or the slave doesn't exist on the bus.

2. The Master(CANoe) sends the header and Response is either sent by Master or Slave.

=> I have a note: when the Master(CANoe) is master then there is no other master on the bus.

Best regards,

Okay understood now. Thank you so much for your quick response

Hi itsnewforme,

In the case of using the CANoe, we need setup a CANoe configuration as a master for the test. And then, they can trace all the frames that transmitted on the bus in the trace window.

To make it easy to understand, I have a example about CANoe configuration.

1. In this case no frame is transmitted on the bus.

2. In this case CANoe sends 2 headers(Break, Sync, PID) on the bus. And then the slave just sends the response with the header containing the PID as its publisher.

Best regards,

Dan

How did you created the second condition where Master sends a header with no Response ?

Thanks in advance

Hi itsnewforme,

This is an example of CANoe's configuration(Attached) that has been used to test.

In this configuration, please see into CANoeTest.can. You can call UserSendheaderNoResponse() function to send a header with no response.

These is the frames that have been sent on the bus:
