IQANdesign 6.08.28 did not fix MD4 CAN C & D Issues ?

Matt 2 months ago in IQANdesign updated by Gustav Widén (System support) 4 weeks ago 2

Hi all. I did some testing on 3 MD4-7s with serial numbers after 2302040001. All of them had issues on bus D not communicating with generic CAN devices. Is this a known issue which has a fix in the works? Is there a PCN newer than PCN7432021-53289-3?

I have tried using programs with 6.08.24 and 6.08.28 and still get the same results.

Under review

We are aware of one remaining problem, the known symptom is failure to perform firmware update on IQAN-XC4 modules via MD4 CAN-C /-D. 

In brief, that known issue can be seen when sending lots of outgoing data in rapid succession over C/D. 

I would not expect a normal application with generic CAN to be triggering nearly as many messages that are needed to provoke that error. But it would be good to look at. 

My recommendation is to reach out to the Parker RAE to discuss the details of your application. 


There was a problem with bitrates 100 and 125 kpbs.

IQANdesign 6.08.30 contain new firmware for the co-processor for MD4 CAN-C/D that fix this, see
