deviceaccesslist

class DeviceAccessList(iterable=(), /)

Bases: list[DeviceAccess]

abstractmethod add_devices(devices)

Add a DeviceAccess to this list

abstractmethod check_device_availability()

Check if all devices in the list are available and accessible.

Returns:

bool – True if all devices are available, False otherwise

abstractmethod get()

Return a list of setpoints of control system device variables

abstractmethod get_devices()

Get the DeviceAccess list

abstractmethod get_range()

Get the valid range for the device variables.

Returns:

list[float] – List containing [min, max] values

abstractmethod readback()

Return the measured variables

abstractmethod set(value)

Write a list of control system device variable (i.e. a power supply currents)

abstractmethod set_and_wait(value)

Write a list control system device variable (i.e. a power supply currents)

abstractmethod unit()

Return the variable unit
