secop_ophyd.SECoPSignal#

Module Contents#

Classes#

AttributeType

LocalBackend

Class for the ‘argument’ and ‘result’ Signal backends of a SECoP_CMD_Device. These Signals act as a local cache for storing the command argument and result.

SECoPXBackend

Signal backend for SignalX of a SECoP_CMD_Device, that handles command execution

SECoPBackend

Unified backend for SECoP Parameters and Properties.

Functions#

Bases: ophyd_async.core.SignalBackend

Class for the ‘argument’ and ‘result’ Signal backends of a SECoP_CMD_Device. These Signals act as a local cache for storing the command argument and result.

Initialization

Initialize SECoP_CMD_IO_Backend

Parameters:

  • path (Path) – Path to the command in the secclient module dict

  • SECoPdtype_obj – detailed SECoP datatype object for bidirectional

Bases: ophyd_async.core.SignalBackend[ophyd_async.core.SignalDatatypeT]

Unified backend for SECoP Parameters and Properties.

This allows a single backend type to be used in signal_backend_factory, with deferred initialization based on annotation metadata.

Initialization

Initialize backend (supports deferred initialization).

Args:

datatype: Optional datatype for the signal path: Optional path for immediate initialization (module:param or prop_key) secclient: Optional SECoP client for immediate initialization
