LIPOWSKY Baby-LIN-3 Bus Simulator with Gigital User Guide

LIPOWSKY Baby-LIN-3 Bus Simulator with Gigital User Guide

Introduction

This getting started guide will show you how to setup the Baby-LIN-3 Family to communicate with or monitor the LIN-Bus. Simply follow the next steps.

Information
This guide is made for new Baby-LIN-3 Family users. If you already have experience with Baby-LIN products or you are an advanced LIN-Bus user then this guide probably is not suited for you.

Information
This guide assumes you are using a Microsoft Windows operating system. If you use a Linux operating system please contact us to receive software for your distribution.

For this purpose, we will introduce the following components to you:

• LIN description file (LDF)
• Signal description
• Specification Diagnosis Services

From this information, the SessionDescriptionFile (SDF) can be created. The SDF is the linchpin in LINWorks-based applications.

The following graphic shows the typical workflow of a LIN-based application with our Baby-LIN-3 Family.

This diagram shows how the individual LINWorks software applications are linked to each other.

Getting started

Introduction

This getting started guide will show you how to create your Lin application using the information from the LDF and the signal descriptions. In the following, you will learn how to create an LDF and integrate it into the SDF. Furthermore, the Unifeid Diagnostic Services will be introduced. After you have successfully created the SDF, the Baby-LIN-3 Family can be operated in standalone mode, LIN bus data can be logged, or macros can be defined for autostart.

Information
This guide assumes you are using a Microsoft Windows operating system.

Installation

Before you can start using the Baby-LIN-3 Family you have to install several components of the LINWorks software.

If you have not already downloaded the LINWorks software, please download it now from our website under following link: www.lipowsky.de

The following components are required for this getting started guide:

• Baby-LIN driver
• Session Conf
• Simple Menu
• LDF Edit

Session Description File (SDF)

How to create a LIN application

1. Requirement
   
   A LIN node (slave) and a suitable LDF file are available. An application is to be implemented in which a simulated LIN master allows the node to be operated in a certain way.

2. Requirement
   
   However, the information in the LDF is usually not sufficient. The LDF describes the access and interpretation of the signals, but the LDF does not describe the functional logic behind these signals. Therefore you need an additional signal description which describes the functional logic of the signals.

3. **Requirement

** If the task also requires diagnostic communication, a specification of the diagnostic services supported by the nodes is also required. In the LDF, only the frames with the respective data bytes are defined, but not their meaning

These requirements can then be defined and edited together in a Session Description file (SDF).

Introduction

Introduction

The Session Description file (SDF) contains the bus simulation based on the LDF data. The logic of the individual frames and signals can be programmed
by macros and events. In addition to the LDF LIN schedule, further diagnostic services can be implemented in the SDF via protocols.

This makes the SDF the central working point of all Linework’s applications.

Create a SDF

The SessionConf software application is used to create and edit the SDF. For this purpose, an existing LDF is imported.

Common Setup

Emulation

Select Emulation in the navigation menu on the left. Here you can select which nodes you want to be simulated by the Baby-LIN-3 Family . If you only want to monitor the LIN-Bus, select nothing.

GUI-Elements

Select GUI-Elements in the navigation menu on the left. Here you can add signals you want to monitor.

Information
There are other ways to monitor frames and signals, but this is a good and configurable starting point.

Virtual signals

Virtual signals can store values just like bus signals, but they do not appear on the bus. They can be used for many different tasks like:

• Temporary values, like counters
• Store constants
• Operands and results from calculations
• etc.

The size of a virtual signal can be set to 1…64 bits. important for use in the protocol feature.
Each signal has a default value that is set when the SDF is loaded.

System signals

System signals are virtual signals with reserved names. When a system signal is applied, a virtual signal is created at the same time and linked to a specific behavior.

In this way, you can access timer, input and output resources and system information.

Information
For more information and a list of all available system signals, please check the System Signal Wizard in Session Cont.

Macros

Macros are used to combine multiple operations into a sequence. Macros can be started by events or, can also be called from other macros in the sense of a Goto or Gosub. The DLL API calls a macro with the macro_execute command.

All Macro Commands can use signals from the LDF and signals from the Virtual Signal section like the system signals.

Another important function of the macros is to control the bus. The bus can be started and stopped via macro. Furthermore, the schedule can be selected and the status of the bus can be checked with the help of the system signals.

Each macro always provides 13 local signals:

LocalVariable1, _LocalVariable2, …, _LocalVarable10, _Failure, _Result Last Macro Command, _Return
The last 3 provide a mechanism to return values to a callcontext _Return, _Failure) or to check the result of a previous macro command. The signals _LocalVariableX can be used e.g. as temporary variables in a macro.

A macro can receive up to 10 parameters when called. In the macro definition, you can give these parameters names, which are then displayed on the left in the menu tree in brackets after the macro name. The parameters end up in the signals _LocalVariable1…10 of the called. If no parameters or less than 10 parameters are are passed, the remaining _Local Variable signals receive the value 0.

Example SDF

You can download the example SDF under the section “08 | Examples SDF´s” under the following link: Getting Started_ Example. sdf

Start the bus communication

Start the SimpleMenu. You should be able to find your Baby-LIN-3 in the device list on the left. Click the connect button and then load the SDF you created earlier.

Now you can see the variables you added to monitor. To start the simulation/monitoring click on the start button.

Now you will see the changes of these signals.

Updates

Update philosophy

The functionality and features of the Baby-LIN-3 are defined by the installed firmware as well as the used versions of the LINWorks and Baby-LIN-DLL.

As we are permanently working on product improvements, the software and firmware are updated periodically. These updates make new features available and solve problems, which have been discovered by our internal tests or have been reported by customers with earlier versions.

All the firmware updates are done in a way, that the updated Baby-LIN-3 will continue to work with an already installed, older LINWorks installation. So updating the Baby-LIN-3 firmware does not mean, that you necessarily have to update your LINWorks installation as well.

Therefor it is highly recommended to always update your Baby-LIN-3 Family to the latest available firmware version.

We also recommend to also update your LINWorks software and Baby-LIN-DLL, if new updates get available. Since new versions of the SessionConf may introduce new features to the SDF format, it is possible that older firmware, SimpleMenu or Baby-LIN-DLL versions are not compatible. Therefor
you should also update them.

If you update your LINWorks it is highly recommended updating the firmware of your Baby-LIN-3 Family to the latest available firmware version as well as distributed the used versions of the Baby-LIN-DLL.

So the sole reason to stay with an older LINWorks version should be, that you use a Baby-LIN-3 with outdated firmware version, which you can’t upgrade for whatever reason.

It is highly recommended updating the Baby-LIN driver to the latest version.
