add_device_tag(val: str)#: add a device tag for this device

describe()#: Describes the device and yields information about the device’s signals, including the signal’s name, source, shape, data type, precision etc.

describe_configuration()#: Describes the device configuration.

property enabled#: Returns True if the device is enabled, otherwise False.

property full_name#: Returns the full name of the device.

get(cached=True)#: Gets the device value.

get_device_config()#: get the device config for this device

get_device_tags() → list#: get the device tags for this device

property high_limit#: Returns the high limit.

property limits#: Returns the device limits.

property low_limit#: Returns the low limit.

property on_failure: OnFailure#: get the failure behaviour for this device

put(value: Any, wait=False)#

Puts the device value. In contrast to the set method, the put method does not return a status object and does not wait for the device to settle. However, the put method can be converted into a blocking call by setting the wait argument to True, which will be equivalent to the set method + wait.

Use the put method if you want to update a value without waiting for the device to settle. Use the set method if you want to update a value and wait for the device to settle.

Parameters:

value (Any) – The value to put.
wait (bool, optional) – If True, the method waits for the device to settle. Defaults to False.

read(cached=True, use_readback=True, filter_to_hints=False)#

Reads the device.

Parameters:

cached (bool, optional) – If True, the cached value is returned. Defaults to True.
use_readback (bool, optional) – If True, the readback value is returned, otherwise the read value. Defaults to True.
filter_to_hints (bool, optional) – If True, the readback value is filtered to the hinted values. Defaults to False.

Returns:

The device signals.

Return type:

dict

read_configuration(cached=True)#

Reads the device configuration.

Parameters:: cached (bool, optional) – If True, the cached value is returned. Defaults to True.

property read_only#: Whether or not the device can be set

property readout_priority: ReadoutPriority#: get the readout priority for this device

remove_device_tag(val: str)#: remove a device tag for this device

property root#: Returns the root object of the device tree.

set(val: Any) → Status#

Sets the device value. This method returns a status object that can be used to wait for the device to settle. In contrast to the put method, the set method can be made into a blocking call by calling the wait method on the returned status object.

Parameters:: val (Any) – The value to set.

set_device_config(val: dict)#: set the device config for this device

set_device_tags(val: list)#: set the device tags for this device

set_user_parameter(val: dict)#: set the user parameter for this device

property software_trigger#: Whether or not the device can be software triggered

trigger(rpc_id: str)#: Triggers the device.

update_config(update: dict) → None#

Updates the device configuration.

Parameters:: update (dict) – The update dictionary.

update_user_parameter(val: dict)#: update the user parameter for this device :param val: New user parameter :type val: dict

property user_parameter: dict#: get the user parameter for this device

property wm: None#: get the current position of a device
