CAN FD – An Introduction

CANopen has been developed by the members of the international user and producer assosiation CAN in Automation (CiA). The CANopen application layer defines different communication services and protocols (e.g. process and service data) as well as a network management. CANopen is mainly used as an embedded network in machinery, but also as a general industrial communications system. It is based on the international standards ISO 11898-1 (CAN protocol) and ISO 11898-2 (fast physical layer). The CANopen application layer has been standardized by the CENELEC and is defined in the European standard EN 50325-4.

Linux is an open operating system. The term “Linux” actually refers to the Kernel of a unix-related operating systemes (derivative). The term is often used as a synonym for the complete operating system (distribution). Further to the programmes necessary in an operating system, e.g. for file and user management, additional graphic frontends, office applications, multi media tools, databases, web browsers and other programmes are covered. Linux is freely available, i.e. the sources are open and the systems may easily be adapted to the individual application. Linux is freely copiable and there are no software license fees and, in addition, it is non-proprietary.

CAN specifications of Bosch form the basis of all CAN implementations and comprise both 2.0A (standard frames) and 2.0B (extended frames) standards. (PDF formate, 189 KByte, in English). You will find a choice of valuable information at www.bosch-semiconductors.com CAN on the internet For more information on CAN please visit the following websites: CAN in Automation e.V. The manufacturer and user organization CAN in Automation offers a wide range of information on CAN. In particular, you will find an overview of higher layer protocols here (e.g. CANopen).

The cable transmitter µCAN.1.sg-TRS is the universal data acquisition module for standard analogue full bridge strain gauge signals. The bridge is powered via the transmitter. The TRS family is ideally suited for being integrated directly in the measuring lines at a short distance from the sensor.Strain gauge full bridge Voltage ± 20 mV Supply voltage 4.5 V Accuracy 0.2% (FS) Resolution 16-bit (1 µV) Sampling rate up to 1kHz Supply of the strain gauge full bridge Fieldbus CAN classic / CAN FD Protocol CANopen / CANopen FD / J1939
