Problem measuring on CAN

Impossible to start measure by CAN
On multi master MC42 + MD3 or MC2 + MD3, on my project it is impossible to start measure (F7) by Canbus, but it works over G11. There is an error.
My system :
Customer support service by UserEcho
What error message do you see in IQANdesign/IQANrun when trying to measure via CAN?
What does it say in the lower right corner of IQANdesign/IQANrun?
If you measure the CAN utilization using IQANanalyze, how high is it before you try to measure?
It is with Iqan design.
I have also had this problem - could not start a measure by CAN, although I could get / send the project via CAN without a problem.
The system is an MD3, XA2 and MC43.
The message I get is the same as Florent.
Thanks. Is this the only error message you get?
Failed to open a new communication session
Or is there also another dialog before or after the one that says failed to open a new communication session ?
What version of IQANdesign?
But I have this error from long time ago (1 year)
the orther message (after the first one)
Gustave do you want the project to test ?
Thank you Florent, if you can send the project and password that would help a lot
You can send it using this link: https://iqan.sharefile.com/share/filedrop
Have you received file ?
Yes, continuing in separate support case.
I am having a similar problem. My customer had an MC2 and wanted to add an MD3 and G11. I am able to load the program to both modules over CAN, and measure the MD3. However, when I click on the MC2 I get the "Measure Terminated" error.
It sounds as if it could be the same issue. Thanks to the information Florent provided, we managed to find a problem that can occur when measuring on CAN in multi-master systems. It is timing dependent and only happens in some applications.
There will be a fix in 5.07 and 6.02
Do you know when 5.07 will be released?
Now that 6.02 is out, I think it will take another week or two to release 5.07 with this fix for the issue with measuring via CAN in multi-master systems.
Solved also in version 5.07, released today.
See release notes case 49820, could happen when switching between applications in IQANdesign while measuring.
