Hey guys,

I'm new to these forums and having a bit of trouble with Simulink which I hope someone can help me with. I'm trying to create a single use switch that reacts to an input by switching something on when the input reaches a certain point but then stays on regardless of what the input then does.

For example: The input is an objects speed and when said objects speed goes above 100 it switches a light on. this light then stays on regardless of the changes in speed of the object i.e. if it goes below 100 it stays on and then if it again goes above 100 it still stays on, the light stays on until the simulation is terminated or reset.

My attempts previously have involved memory blocks and timers but I can't seem to make the switch stay permanently on once it's triggered, essentially I want the functionality of the manual switch but trigger-able by the simulation itself. Unfortunately I am also limited to using R2009a due to the hardware the simulation runs on.

Thanks in advance!
