CANopen Intro: www.csselectronics.com/pages/...
Need a simple intro to CANopen? In this video tutorial we introduce the CANopen protocol incl. the object dictionary, services, SDO, PDO and master/slave nodes.
CANopen is a CAN based communication protocol - used in particular within industrial automation (e.g. robotics), medical equipment and automotive. The protocol enables off-the-shelf integration of CANopen nodes - and easy configuration after installation.
The CANopen protocol has six core concepts: Communication models (master/slave, producer/consumer, client/server), communication protocols (e.g. PDO and SDO services), device states, the Object Dictionary (OD), Electronic Data Sheet (EDS) and device profiles (standardized by CAN in Automation, CiA).
In this intro we also briefly introduce CANopen data logger use cases, including logging CANopen node data, warehouse fleet management, predictive maintenance and blackbox diagnostics.

ABOUT CSS ELECTRONICS
At CSS Electronics we specialize in simple-to-use, pro specs and interoperable CAN bus data loggers - like the CANedge and CLX000 series. The devices let you record raw data from e.g. cars, trucks, industrial machinery and other CAN based applications onto an 8-32 GB SD card. The devices are interoperable, meaning you can process the data in your favorite existing software - or use our 100% free and open source software/API tools.

As a person learning more about CAN hoping to land a career in the autonomous vehicle industry, I thank you very much for such great videos.

@martinfalch4648 4 года назад

Thanks Christones! :-)

@0783155 2 года назад

Thanks! Got a small project with CanOpen to do under high pressure. No previous knowledge in our organization helps too. But this video was really helpful in figuring out the basics.

@martinfalch8016 2 года назад

Awesome to hear :-)

@KangJangkrik 2 года назад

Thanks for sharing! Our team ended up creating a new, more simple protocol due to restriction of low energy controller like STM32. It's called M2TP by the way and it's open source too, currently in development.

@mcejp 2 года назад

This is interesting, but I haven't been able to find any specification of the protocol, and the documentation in general is quite sparse.

@KangJangkrik 2 года назад

@@mcejp which protocol?

Best can open video ...tnxs

@aizentaichou4705 2 года назад

In the object dictionary, there is manufacture, that means the manufacture need to get approval from canopen company to get certified ?

@yassinekhlaf2053 Месяц назад

Good helpful video ! am new learner about CAN protocol in the automotive field , so what steps should i take to learn it the best way cause people say it's one of the hardest protocols and it feels exhausting

@WaleedUddin-mw8uw Год назад

Nice video, provides clarity. Tho one suggestion is that I wished you talked a bit more about PDO mapping

@marciohogenelst 3 года назад

very good

@mehmeteneskaraman7083 Год назад

Hello everyone! Could you help me for a project? I wanna heartbeat for sensors with arduino?

@XWSshow 3 года назад

So the can bus is in the lowest layer of the osi model, and canopen is in the second lowest?

@KangJangkrik 2 года назад

Yes, also there is a possibility for the data to be encoded in BSON format which is supposed to be the highest layer

@siowlimchow7755 3 года назад

So very hard to follow with the speed and the explanation if he is writing a formal essay. Also the speed is a the pace of commercial. I wonder what intention is? to implant the idea? but with so much information, brains need to digest.

@martinfalch4648 3 года назад

Thanks for the feedback - the pacing is perhaps a bit fast, but if you prefer a slower pace I can recommend reading the full article (link is in the description).

@vladshcherbakov3112 Год назад

After 5 years of working with CAN and 19 minutes of this video, I still know nothing about CAN. Completely useless.

@TaylorAlexander 2 года назад

Just a little feedback that a lot of organizations are moving away from “master/slave” language these days. It is honestly hard to listen to this video because of this language. I have noticed for example that the Raspberry Pi foundation no longer uses these terms to describe SPI devices, instead using terms like “SPI TX” and “SPI RX” to reference communications pins rather than old terms like MISO and MOSI. I would have to do some digging to see what other people use but perhaps something like “controller/dependent” could be used. The protocol looks nice! Just wanted to give this specific feedback.
