Attributes

datatype	Datatype of the signal value
put_mock
put_proceeds

datatype: Type[T] | None = None

source(name: str) → str

async connect(timeout: float = 10.0) → None

property put_mock: Mock

property put_proceeds: Event

async put(value: T | None, wait=True, timeout=None)

set_value(value: T)

async get_reading() → Reading

async get_value() → T
