inevent

Show FMU input event ports

Select the check box to enable the input event ports of the FMU import block. The FMU import block has two input event ports: External and End. The External event can be activated by any event and puts the FMU (of type ME) into the event iteration mode. The End event puts the block into terminate mode.

Scalar

outevent

Show FMU output event ports

Select the check box to enable the output event ports of the FMU import block. The FMU import block has two output event ports:Discrete and End. The Discrete event is triggered when a time event is programmed inside the FMU block. The End event is triggered when the FMU requests a termination.
