Dear,
I try to run a multi rate model using function call subsystems.
However, I get following error:
'MasterModel/FastTask/Ctl/M1/Speed/AT_FirstOrderFilter_Reset/AT_DiscreteTimeIntegrator_Backward_Reset/AT_ResetMethod/AT_Ground/Rate Transition' is a rate transition block. A rate transition block is not allowed inside the function call subsystem 'MasterModel/FastTask' unless its input or output port sample time is asynchronous sample time. Consider placing the rate transition block outside the function call subsystem.
Since the rate transition block in the function call subsystem is part of a large custom simulink library, I cannot just remove it or put elsewhere.
How could I resolve this issue?
Kind regards,
Niels

Hi Niels,
I see you are trying run a multi-rate Simulink model using function-call subsystems. However, you are encountering an error for rate transition block that it is not allowed in function call subsystem unless its input/output sample time is asynchronous.
This can be resolved using Asynchronous sample time for input/ output ports.
Refer this documentation for Asynchronous sample time: https://www.mathworks.com/help/simulink/ug/types-of-sample-time.html#mw_cf777000-5fc5-41ec-9f7e-aac1d9b3efcc
Another approach is to linearize your multi-rate model.
Refer this documentation about Linearizing Multirate Models: https://www.mathworks.com/help/slcontrol/ug/linearize-multirate-models.html
Refer this to documentation for Function-Call Subsystems and rete transition block:
Hope this helps!
