"""Setable signal for simulated devices.
The signal will store the value in sim_state of the SimulatedData class of the parent device.
It will also return the value from sim_state when get is called. Compared to the ReadOnlySignal,
this signal can be written to.
The setable signal inherits from the Signal class of ophyd, thus the class attribute needs to be
initiated as a Component (class from ophyd).
