ES523 – CAN FD Interface Module

The ETAS ES523 CAN FD Interface Module is designed for calibration, diagnostics and flash programming of ECUs as well as capture measurement data from ECUs and their environment. It provides 4 CAN and 3 Ethernet connections and supports the new high-performance CAN FD (CAN with flexible data rate) protocol on all CAN channels. Connected measurement modules are provided by power supply via Ethernet interface, which minimizes cabling of the modules. Synchronization of signals captured with the device and the connected ETAS hardware with a time resolution of 1 µs. For integrating the module in other tool environments, ETAS ECU and Bus Interfaces Integration Package (EBI-IP) can be used.

Benefits

  • Rugged compact metal housing
  • 4 electrically isolated CAN channels with Bosch M-CAN controller
  • CAN FD allows data to be transmitted at a rate of up to 5 Mbit/s (under laboratory conditions, higher)
  • Supports both ISO-conform and non-ISO-conform (CAN FD V1) Version of the CAN FD protocol
  • Device wake-up via two CAN channels
  • 3 Fast Ethernet ports with integrated power supply for connecting additional ETAS interface or measurement modules
  • Acquisition of time synchronous measurements
  • Open interface for integration with existing tool environments

Time-synchronous acquisition of measurement data

The ES523 module synchronizes all signals that are measured over the CAN and Ethernet channels. This makes the module ideally suited to the task of capturing signals transmitted in short time frames from an ECU via Ethernet through an XETK interface synchronously with CAN and CAN FD signals.

 

Flexible addition of measurement technology

In addition to ECUs and vehicle buses, the Ethernet measurement modules of the ETAS ES400 and ES600 product families can be connected to the interface module. The measurement modules are then powered via connections built into the Ethernet connectors.

 

Supported software

The ES523 module is supported by the software INCA, the ETAS tool for measuring and ECU calibration, from version 7.1.7 onward and the INCA ODX-LINK and ODX-FLASH add-ons for ECU diagnostics and flash programming from version 1.5.7 onward. In conjunction with the BUSMASTER open-source software tool, the ES523 module can be used to simulate, analyze, and test CAN FD networks. In addition, the ETAS Hardware Service Pack (HSP) supplies firmware updates from version 10.7.0 onward.

 

Open interface

ETAS’ EBI-IP (ECU and Bus Interfaces Integration Package) software package enables users to integrate ECU and bus interfaces with third-party applications. The package is available for free from the download center on ETAS’ website.

 

CAN FD

CAN FD (CAN with flexible data rate) is an improved, backward-compatible CAN protocol developed by Bosch. The principal differences to CAN consist in the increased payload data per message from 8 to 64 bytes, the higher transmission speeds of up to 8 Mbit/s, and the longer checksums, which enhance transfer reliability. CAN FD meets the automotive industry’s need for higher bandwidth for networks. At the same time, CAN FD nodes can be easily integrated into existing CAN infrastructure.
