pcdsdevices.twincat_motor.InvertedBoolEpicsSignal

class pcdsdevices.twincat_motor.InvertedBoolEpicsSignal(derived_from, *, write_access=None, name=None, parent=None, **kwargs)

Methods

describe(): Description based on the original signal description

forward(value): Compute derived signal value -> original signal value

get(**kwargs): Get the value from the original signal, with inverse applied to it

inverse(value: bool): Convert motor limit enable to switch state: it’s the inverse.

read()

Put the status of the signal into a simple dictionary format for data acquisition

Returns:: dict

read_configuration(): Dictionary mapping names to value dicts with keys: value, timestamp

set(value, *, timeout=None, settle_time=None, **kwargs)

Set the value of the Signal and return a Status object.

Returns:: st (Status) – This status object will be finished upon return in the case of basic soft Signals

trigger(): Call that is used by bluesky prior to read()

Attributes

SUB_META = 'meta'

connected: Mirrors the connection state of the original signal

derived_from: Signal that this one is derived from

high_limit: The high, inclusive control limit for the Signal

hints: Field hints for plotting

kind

limits: Limits from the original signal (low, high), such that low <= value <= high

low_limit: The low, inclusive control limit for the Signal

metadata: A copy of the metadata dictionary associated with the signal

metadata_keys: Metadata keys that will be passed along on value subscriptions

read_access: Can the signal be read?

source_name

subscriptions: ClassVar[FrozenSet[str]] = frozenset({'meta', 'value'})

timestamp: Timestamp of the readback value

tolerance: The absolute tolerance associated with the value.

value: The signal’s value

write_access: Can the signal be written to?
