[etherlab-users] Multirate system - Simulink fundamental sample time / Ethercat bus frequency

Hello Etherlab-Users,

I'm using a slave with a minimal sample time of 125e-6 s but due to numerical stability, I need to calculate some subsystems of the Simulink model more often (have a lower sample time). These subsystems do not contain Ethercat-component blocks. Has anybody experience with this?

It seems that the models fundamental sample time always determines the Ethercat bus cycle time. Is it possible to set the Ethercat cycle frequency to a lower value than the fundamental sample frequency?

Any idea or hint would be greatly appreciated.

thanks for reading and a happy new year!
