What is the meaning of this error message in Simulink?

Question

Upon execution of a Simulink model, I received following error:

The sample time propagated to '[...]/Discrete-Time Integrator' is not discrete but [0, 1]. Specify a discrete sample time in the source of the incoming signal.

Where can I find documentation about this error?

(I cannot post my model due to copyright restrictions. If needed, I will provide an MWE.)

Answer 1

You can read up about the different types of sample times here. A discrete sample time is the simple case, where the blocks are evaluated every t seconds. The block you have chosen only supports this kind of sample time.

To resolve the error, you must chose one of the two possibilities:

• Make the source signal discrete
• for the likely case that your source is continuous, choose the continuous integral
