CANlog 3 and CANlog 4

The Data Recorder for CAN and LIN Buses

Download Datasheet

CANlog 3 and CANlog 4 are the perfect tools to log messages from CAN and LIN buses and then evaluate them later. They also function as the ideal data recorder for both simple and challenging logging tasks.

Features and Advantages

CANlog 3 and CANlog 4 are the optimal tools for logging the data communication of a CAN and LIN system. Messages can be received, saved, and evaluated according to the loaded configuration. With its low current consumption in sleep mode CANlog is also an excellent choice for in-vehicle testing and use in test fleets.

Application Areas

The main functionalities of CANlog can also be used simultaneously:

• Data logger
  Data Logger: It is easy to filter, receive, log and send messages and signals using CANlog.
• Classing Device
  CANlog is especially well equipped for processing the logged data, editing it, and creating classing tables.
• Gateway
  If there is an ECU that should not be connected directly to the CAN bus, as an alternative CANlog could be used as a gateway for indirect bus interfacing.

Functions

CANlog 3 and CANlog 4 each support up to four CAN channels. Furthermore, CANlog 4 has a CAN channel that can be used as a measurement channel. Optional I/O boards may be used to expand CANlog 3 and CANlog 4 with additional digital inputs and outputs, analog inputs, or a LIN interface. The data are saved in internal memory, and with CANlog 4 there is the option of saving data to interchangeable flash cards.

The configuration program included with the product allows the user to create a configuration customized for different applications and goals. There are functions for using CANlog as a data logger, classing device, gateway, tachograph, and for rainflow analysis.

Integration

The trigger conditions defined in CANalyzer/DENalyzer and CANoe/DENoe (single trigger or entire measurement) for logging a trigger block can also be utilized in CANlog.

Triggers are set up in the configuration for triggering on messages, signals, error frames, and message timeouts. Various message filters may also be set up in the configuration. Other complex trigger conditions can be formulated using the CANlog configuration language.

The logged data traffic can be read into CANalyzer and CANoe, where it can be evaluated using familiar analysis functions. The interface for CANlog 3 and CANlog 4 is included in CANalyzer and CANoe, Version 3.1 or higher.

Project Database

A project database can be used to assign project-specific names, conversion formulas, units, and other attributes to messages and their signals. The database is set up and maintained using the program CANdb++. It allows messages and their signals to be represented on the application level (e.g. CarSpeed = 210 km/h). It is easy to select such messages and signals when defining trigger conditions for MultiLog. CANdb++ is included with delivery of CANalyzer and CANoe.
