Hi John,
I understand you are facing an issue where blocks like “z⁻¹”, “Sum”, and “Gain” do not inherit the event-based sample time from a “SimEvents Entity Generator”. This happens because these standard Simulink blocks are designed for “time-based” signals and are not compatible with “event-based” inputs (purple lines).
To resolve this issue, you can refer to one of the following workarounds:
1. Use a “Discrete-Event Subsystem” - Place your logic inside a “Discrete-Event Subsystem”, which is designed to handle “event-based” signals.
2. Use “Triggered Subsystem” - Convert event arrivals into scalar signals and then use them to trigger regular Simulink logic using a “Triggered Subsystem”.
3. Store Values as Attributes - Instead of using “z⁻¹”, store and manipulate previous values using “entity” attributes in “SimEvents blocks”.
Do note that setting the sample time to “-1” works for discrete time inheritance, not event-based. Hence, event signals need to be handled using event-compatible blocks or subsystems.
For more reference, refer to the following official documentation:
