BABY-LIN-RM-III

Part No.: MPLPS-BABY-LIN-RM-III
LIN- and CAN-Bus simulator with digital I/O interface

Product Description

Description

The Baby-LIN-RM-III allows LIN and CAN Bus equipped devices to be controlled using a standard personal computer. After installing the supplied LINWorks software, you can connect the Baby-LIN-RM-III to an available USB port and access LIN and CAN Bus devices via LINWorks or custom applications using the Baby-LIN-DLL.

In addition, LIN and CAN devices can be controlled and evaluated using inputs and outputs only. This enhances PLC (Programmable Logic Controller)-based testing facilities with LIN or CAN Bus capabilities without significant effort. This can be particularly beneficial for facilities performing long-term testing.

The Baby-LIN-RM-III provides 8 digital inputs, 3 analog inputs and 6 digital outputs. Two of the digital inputs can read, scale and map PWM (Pulse Width Modulation) signals to bus signals.

Furthermore, the module's digital outputs can be controlled by bus signal values. For example, an output can be set when a signal equals, does not equal, is greater than or less than a reference value. It can also be tested whether a specific signal value is within a defined range.

All digital outputs can also be configured to output PWM signals.

In addition, the Baby-LIN-RM-III offers two programmable buttons. They can, for example, be used to start and stop LIN or CAN Bus communication. They can also be assigned to many other functions.

The CAN Bus interfaces (1) of the Baby-LIN-RM-III support CAN FD and are backward compatible with CAN-HS. Both CAN Bus interfaces feature switchable termination resistors. One of the interfaces can be switched to a Fault Tolerant CAN-LS interface.

The Baby-LIN-RM-III has a microSD card slot (1), which can be used for logging purposes. The associated LED indicates the logging status as well as the firmware update and boot status.

The Baby-LIN-RM-III supports LIN Bus voltages in the range of 8-26 VDC. All communication interfaces (LIN Bus, CAN Bus and USB) are galvanically isolated, eliminating interference between the PC and the board electronics.

Only four digital outputs use the ground of the board's logic supply. Two of the digital outputs are galvanically isolated.

The Baby-LIN-RM-III includes its own 32-bit microcontroller, which handles all time-critical tasks of the LIN Bus protocol.

The device firmware is field-updatable, allowing the device to easily adapt to changes in bus specifications and upcoming new system features.

The Baby-LIN-RM-III supports SDF-V3. This new generation of SDF enables features such as multiple bus sections, conditional macro commands, new system variables, new CRC functions and sub-macro calls.

(1) This function requires additional software license(s). See the Ordering Information for details.
 

Operation Mode

Any situation that requires communication with a LIN or CAN device is a potential field of application for the Baby-LIN-RM-III. It is a versatile tool that can be used in research laboratories, test departments and production environments (EOL applications).

  • Monitor and log all frames on the bus without the need for an SDF. If an SDF is available, signal values can also be monitored.
  • Control the bus via the LINWorks software or customer-specific applications using the Baby-LIN-DLL.
  • Program and store freely programmable command sequences in the Baby-LIN-RM-III to operate it as a standalone device without the need for a PC. This allows a bus-driven ECU to be operated during durability testing or EOL applications without a connected PC.

Simulation Modes

The Baby-LIN-RM-III is able to simulate different configurations of LIN Bus and CAN Bus nodes. It is possible to simulate any number of nodes, ranging from none to all. These are some typical configurations:

  • LIN Bus: Simulate the LIN Bus Master to operate Slave nodes.
  • LIN Bus: Simulate any number of LIN Bus Slave nodes.
  • LIN Bus: Simulate all nodes and therefore the complete communication on the bus.
  • CAN Bus: Simulate any number of CAN Bus nodes.
  • LIN Bus and CAN Bus: Simulate all but one node and realize a Residual Bus Simulation.
  • LIN Bus and CAN Bus: Simulate no nodes to monitor the bus communication only.

Simulations for the LIN Bus and CAN Bus can be performed simultaneously.
 

LIN- and CAN-Bus Properties

The used LIN Driver supports bus voltages of 8-26 VDC and can be used up to 115200 Baud. This allows even nodes that operate outside the standard limits of the LIN specifications to be controlled with the Baby-LIN-RM-III.

Supported LIN versions are V1.2, V1.3, ... V2.2. The Pull-up resistor of the LIN Bus Driver is switched to 1 kOhm when the Master node is emulated and to 30 kOhm when only Slave nodes are emulated.

Both CAN Bus interfaces of the Baby-LIN-RM-III are designed as CAN FD interfaces according to ISO 11898-1:2015 with an MCP2562FD Driver. They support data Baud rates up to 8 Mbit/s.

Both CAN Bus interfaces can be used as CAN High-Speed interfaces according to ISO 11898.

The second CAN Bus interface can be switched to a Fault Tolerant Low-Speed physical layer according to ISO 11519 with a TJA1055 Driver.

The maximum supported signal cable length for the LIN Bus and CAN Bus is 30 m, but may be shorter depending on the bus assembly.
 

LINWorks Suite

The purchase of a Baby-LIN-RM-III includes a license to download the LINWorks suite. This suite is a collection of PC software that supports you throughout the entire workflow.

LDFEdit allows the inspection, creation and editing of an LDFile (LIN Description File).

SessionConf allows the inspection, creation and editing of an SDFile (Session Description File), and supports importing LDF files for LIN Bus simulation and DBC files for CAN Bus simulation. It defines everything required for a complete simulation of each available bus, such as which nodes are available on each bus and which nodes should be simulated by the Baby-LIN-RM-III. It also allows application logic to be defined. This programming capability is available for each device out of the box.

SimpleMenu is used to establish a connection to the Baby-LIN-RM-III, upload SDF files, change the device target configuration, control the bus, and monitor frames and signals on the bus. Even without an LDFile, DBC file or SDFile, the bus can be monitored and frames can be logged.

Baby-LIN-DLL allows customers to create their own applications and use all features of the Baby-LIN-RM-III, such as controlling and monitoring the LIN Bus and CAN Bus interfaces. Baby-LIN-DLL is a native C/C++ DLL and is available for Windows, Linux and Raspberry Pi. Wrappers for .NET, Python, VB6 and LabVIEW are also available. Examples are provided for all supported programming languages.

LogViewer can display and convert log files generated by the Baby-LIN-RM-III and SimpleMenu.

The LINWorks software runs on 32-bit and 64-bit versions of Windows 10 and higher.
