Simulateur de bus CAN/LIN Lipowsky Baby-LIN-RM-III

The Baby-LIN-RM-III is a controller that can be used to control LIN or CAN interface using a standard computer. This device comes with an integrated 32-bit microcontroller that can perform all time-critical operations.

LINWorks V2 Software

The Baby-LIN-RM-III includes the easy-to-use LINWorks V2 software suite.

Based on LDF or DBC files configurations can be set up within minutes. Each configuration can define which nodes from the bus will be simulated by the Baby-LIN-RM-III (restbus simulation) or how a change of state at the digital inputs will change bus signals or trigger a macro. Via the digital inputs PWM signals can be read, scaled and mapped to bus signals.

Signal values can be read can be read and written in real-time while other operations are in progress. This can be done via a Simple Menu found in the LINWorks suite or by a custom product or even via the API functions of a supplied DLL.

Operating System Compatibility

The LINWorks-V2 software suite is compatible to Win-XP, Win7, Win8 and Win10 (16 and 32-bit). A Linux version is available upon request.

Digital I/O

Also, the module's digital outputs can be controlled by the values of the bus signals. For instance; an output can be set, if a signal is equal to, not equal to, greater or less than a reference value. It also can be tested, if a certain signal value is within a given range or not.

LIN Bus Interface

The implemented LIN driver supports bus voltages up to 36 volts and can be used to up to 200 Kbit/s. These way even nodes that operate outside the standard limits of the LIN specifications can be controlled with the Baby-LIN-RM-III.

CAN Bus Interface

One CAN interface is designed as a high-speed interface, conforming to ISO-11898 with a SN65HVD251 driver while the other interface utilises a fault-tolerant low-speed physical layer conforming to ISO-11519 with a TJA1054 transceiver.

Galvanically Isolated Interfaces

All communication interfaces (LIN, CAN and USB) as well as the digital inputs are galvanically isolated from the module's logic circuit.

Programmable Buttons

Additionally, the Baby-LIN-RM-II offers two programmable buttons that may be configured to control the start and stop functions of the bus.

Stand-alone Operation

The configuration designed on a computer can be transferred to and stored on the device, allowing you to use the controller as a standalone device, without any computer.

Applications

The Baby-LIN-RM-III makes is easy to add LIN or CAN bus communication capabilities to PLC-based test equipment such as durability test facilities, validation tests etc. The Baby-LIN-RM-II is equipped with a powerful 32-bit microcontroller that handles all time-critical operations such as message formatting and the decoding of the bus protocol.
