CAN Transmission speed

Masia Jean-Baptiste 9 years ago in IQANdesign • updated by Wilfried 9 years ago • 1

Hello


Here's my system

Image 278


Following a slow sampling time, I've changed the MD4 and Mc3 to put a 10ms.
Now the CAN frames emmise by MC3 to MD4 are not always read by the Md4.
The cycle time can it affect the speeds of the CAN messages between two master module ?


Best regards

Hello

My advice is to check the CAN trafic with IQAN-Analyse on the different busses.

Then you can see directly, how many trafic you have.

If the busload on one of the CAN busses exceeds 70 - 80%, I advice to increase the cycle time.
