CAN BUS and CAN FD
Interfaces and Analysers

Automotive Bus Interfaces

Dewesoft offers support for several standard automotive interfaces for analyzing and inspecting vehicle bus data. Data can be captured from all the supported interfaces and synchronized with other sources like analog, video, and others...

Supported automotive interfaces:

• CAN Bus (see CAN Bus Analyzers)
• OBDII on CAN (see CAN OBDII)
• J1939 and J1587
• CAN FD (see our CAN FD Bus Analyzers)
• XCP/CCP
• LIN bus
• FlexRay
• Kistler KiRoad
• MTS road simulator integration
• Testbed AK-protocol support
• ETAS INCA over CAN
• SENT (SAE J2716)

CAN Bus Data

Dewesoft X can interface with all Dewesoft CAN and CAN FD devices which are a dominated vehicle bus interfaces found in today's vehicles. Dewesoft X can decode any kind of data from the CAN bus in read-only or acknowledge mode. Support for OBDII on CAN, J1939, and J1587 standards is also available.

Dewesoft X makes it extremely easy to setup CAN channels. The software can import and export CAN DBC or XML files. DBC files are common files for CAN message and channel definition. After the import software will automatically set up all available CAN channels and decode CAN messages.

CAN FD

Dewesoft X can interface with our CAN FD devices to read, store, and analyze the CAN FD data from the vehicle CAN bus. 

Key features

• Synchronized CAN FD acquisition with other sources like analog, digital, video, GPS, etc.
• Decode, store and send CAN FD messages
• Dual baud rate up to 12 MBit/sec
• Message decoding up to 64 bytes
• Support for CAN DBC or XML file import and export for easy setup of CAN FD channels

XCP/CCP

Dewesoft X offers support for XCP and CCP protocols via XCP/CCP plugins.

The plugin enables data acquisition from Electronic Control Units (ECUs) supporting CCP or XCP over CAN or Ethernet protocol. It supports multiple ECU's. No additional HW is needed except CAN or Ethernet port.

• XCP Master Deweso​​​​​​​ft X Online Manual

XCP Devices

Next to XCP Slave and Master plugins, Dewesoft also introduced SIRIUS XHS and IOLITE LX devices which can natively serve data via XCP on Ethernet without the need of any software. You can watch a short presentation video.

FlexRay

FlexRay is an automotive network communications protocol developed by the FlexRay Consortium to govern on-board automotive computing. It is designed to be faster and more reliable than CAN.

Dewsoft X data acquisition software offers support for FlexRay protocol with the FIBEX library import option. All Vector FlexRay cards are supported.

LIN bus 

The LIN bus plugin allows you to simply connect and listen to communication on multiple LIN networks. Using Vector hardware, it mimics listen-only slaves that listen to all data transmission on the bus. Decoding can be done in three different forms:

• analog data with extensive scaling options,
• discrete data
• a mix of both.

The plugin supports importing the configuration from LIN description files (LDF). To read the LIN bus, a Vector LIN card is required.

SENT (SAE J2716)

The SENT protocol (Single Edge Nibble Transmission - SAE J2716) is a data transmission protocol that has seen a big increase in use, especially in the automotive industry. The module developed decodes a SENT signal transmitted from a sensor using counter channels.

The module supports two fast channels and any number of slow channels, which are detected automatically. The SENT signals can be decoded from multiple sensors simultaneously while each sensor is using a dedicated counter channel.

CAN FD Analyzer

The bandwidth requirement of new automotive applications is rapidly increasing. Automotive OEMs are thus introducing CAN FD in new cars. CAN FD can provide significantly increased bandwidth due to increased data clock rates, and to larger data payloads. CAN-FD is used with an increase in the number of sensors inside the vehicle and is much faster than the normal CAN2.0 - which is limited to 1Mbps.

KRYPTONi-1xCAN-FD is a single port CAN FD device that uses EtherCAT as a data interface. It supports high-speed CAN interface with data rates up to 8 Mbps. Besides this, CAN FD also supports the CAN2.0 communication protocol as well as special protocols such as J1939, where CAN out is used as read-only.

The new KRYPTONi-1xCAN-FD uses galvanically isolated communication lines and an isolated sensor supply of +5 V and +12 V. Power limit for the sensor supply is 1.4 W.

This product is the latest member of the award-winning KRYPTON ONE product line. A line designed for extreme conditions with an operating temperature range between -40°C and +85 °C and IP67 rating.

KRYPTONi-1xCAN-FD is supplied in a standard KRYPTON ONE chassis with a DSUB9 input connector.
 

OBD II, J1939, and XCP/CCP protocols

Dewesoft CAN bus devices also offer OBD II, SAE J1939, XCP, and CCP protocol support. 

OBDII functionality provides real-time data acquisition of wide range vehicle parameters available over vehicle standard OBD II port. It only supports OBD II over CAN which is mandatory on all new cars developed after 2008.

Data acquisition from Electronic Control Units (ECUs) supporting CCP or XCP protocol (over CAN or Ethernet) is also possible with no additional hardware.

Synchronization With Analog Data

All configured CAN channels are perfectly synchronized down to microseconds with any other data sources like analog, digital, video, etc.. The synchronization will be pinpoint even if the sampling rates between different data sources are completely different.

CAN and CAN FD devices come with built-in synchronization port which allows for hardware synchronization with other Dewesoft data acquisition systems like SIRIUS, KRYPTON or DEWE-43.
