Requirements to simulate a Smart Component?

I’m a new user of Robotstudio and I’m trying to test a Smart Component.
I’ve created a simple gripper with a line sensor and saved it as a library.

If I open a station with a robot and controller and import the library, I can play simulation and check the Smart component.

If I create a new station and import the library (without any other component), when I go to the Simulation Tab and click the ‘Play’ icon, the simulation doesn’t start.
Do I need a robot, a VC or some other component to test a Smart Component?

Hello,
In Simulation Setup, you can check which component is to be simulate.

I’ve checked the simulation setup and the components (smart component and line sensor) are selected.
The problem is that when I click the “Start” button in simulation setup, simulation doesn’t start (no warnings, no errors, the pause an stop buttons continue inactive… the program doesn’t do anything).
If I import the component to a project with a robot, VC and other components… the simulation start without any problem (I can can pause and stop the simulation and check the line sensor status).

i have a similar Problem, but only with versions bigger than 2023.2
i think i know the reason - the simulation runs only for one zycletime.
my workaround is: but a roboter and a controler to the system and then you can set the cycle mode to continous and everything works.
i dont know if this is a bug or it si wanted because the main goal is robotersimulation
