Getting started

2.1 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 Unified Diagnostic Services will be introduced. After you have successfully created the SDF, the Baby-LIN-MB-II can be operated in standalone mode, LIN bus data can be logged, or macros can be defined for autostart.

Note 12 Advice
This guide assumes you are using a Microsoft Windows operating system.

2.2 Installation
Before you can start using the Baby-LIN-MB-II 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
  • SessionConf
  • SimpleMenu
  • LDFEdit

Session Description File (SDF)

3.1 How to create a LIN application

  1. Requirement
    LIPOWSKY Baby LIN MB II LIN and CAN Bus Simulator with Rs 232 Ethernet Interface - Icon

    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
    LIPOWSKY Baby LIN MB II LIN and CAN Bus Simulator with Rs 232 Ethernet Interface - Icon 1
    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 that describes the functional logic of the signals.
  3. Requirement
    LIPOWSKY Baby LIN MB II LIN and CAN Bus Simulator with Rs 232 Ethernet Interface - Icon 2
    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).

3.2 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 LINWorks applications.

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

3.4 Common Setup
3.4.1 Emulation
Select Emulation in the navigation menu on the left. Here you can select which nodes you want to be stimulated by the Baby-LIN-MB-II. If you only want to monitor the LIN-Bus, select nothing.

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

LIPOWSKY Baby LIN MB II LIN and CAN Bus Simulator with Rs 232 Ethernet Interface - monitor

Note 12 Advice
There are other ways to monitor frames and signals, but this is a good and configurable starting point.

3.4.3 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.

3.4.4 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 the timer, input and output resources, and system information.

Note 12Advice
For more information and a list of all available system signals, please check the System Signal Wizard in SessionConf.

3.4.5 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.

LIPOWSKY Baby LIN MB II LIN and CAN Bus Simulator with Rs 232 Ethernet Interface - DLL

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 a macro. Furthermore, the schedule can be selected and the status of the bus can be checked with the help of the system signals.

LIPOWSKY Baby LIN MB II LIN and CAN Bus Simulator with Rs 232 Ethernet Interface - bus

Each macro always provides 13 local signals: _LocalVariable1, _LocalVariable2, …, _LocalVarable10, _Failure, _ResultLastMacroCommand, _Return
The last 3 provide a mechanism to return values to a call context _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.

LIPOWSKY Baby LIN MB II LIN and CAN Bus Simulator with Rs 232 Ethernet Interface - 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 passed, the remaining _LocalVariableX signals receive the value 0.

3.5 Example SDF
You can download the example SDF under the section “08  Examples SDF ➫ s” under the following link: GettingStarted_Example.sdf

Start the bus communication

4.1 via SimpleMenu

Updates

5.1 Update philosophy
The functionality and features of the Baby-LIN-MB-II are defined by the installed firmware as well as the used versions of the LINWorks and Baby-LINDELL.
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-MB-II will continue to work with an already installed, older LINWorks installation.
So updating the Baby-LIN-MB-II firmware does not mean, that you necessarily have to update your LINWorks installation as well.
Therefore it is highly recommended to always update your Baby-LIN-MB-II 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. Therefore you should also update them.
If you update your LINWorks it is highly recommended to update the firmware of your Baby-LIN-MB-II 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-MB-II with an outdated firmware version, which you can’t upgrade for whatever reason.
It is highly recommended updating the
Baby-LIN driver to the latest version.

5.2 Downloads
The latest version of our software, fimrware and documents can be found in the download area on our website www.lipowsky.de .
