Their group_layout is set to GroupLayout.INLINE so PVI renders them as Grid panels on the top-level server screen. PVI forbids nesting a Group(Grid()) inside another Group, so couplers must be at the server level (not inside the device SubScreen) to appear inline. Their FastCS PV paths are unchanged — path resolution is independent of the FastCS parent-child hierarchy. Multi-segment-path couplers (e.g. BL04I-EA-CATIO-01:ETH01:E1RIO01) are unaffected and remain as SubScreen children of the device. --- src/fastcs_catio/catio_controller.py | 195 ++++++++++++-- src/fastcs_catio/devices.py | 21 -- src/fastcs_catio/fastcs.yaml | 8 +- src/fastcs_catio/schema.json | 89 ++++++- tests/test_catio_units.py | 378 +++++++++++++++++++-------- 5 files changed, 540 insertions(+), 151 deletions(-) diff --git a/src/fastcs_catio/catio_controller.py b/src/fastcs_catio/catio_controller.py index 49afd5e..034fccf 100644 --- a/src/fastcs_catio/catio_controller.py +++ b/src/fastcs_catio/catio_controller.py @@ -12,7 +12,7 @@ import numpy as np import numpy.typing as npt from fastcs.attributes import Attribute, AttrR -from fastcs.controllers import Controller +from fastcs.controllers import Controller, GroupLayout from fastcs.datatypes import Int, String, Waveform from fastcs.methods import scan from fastcs.tracer import Tracer @@ -34,7 +34,6 @@ check_ndarray, filetime_to_dt, get_notification_changes, - make_node_prefix, process_notifications, trim_ecat_name, ) @@ -74,6 +73,7 @@ def __init__( # comments: str = "" # TO DO: can comments attribute be written to hardware? *, path: list[str] | None = None, + group_layout: GroupLayout | None = None, ): # tracer.log_event("CATio controller creation", topic=self, name=name) @@ -123,6 +123,7 @@ def __init__( ), ], path=path, + group_layout=group_layout, ) @property @@ -246,7 +247,7 @@ async def add_subcontrollers(self, subcontrollers: list["CATioController"]) -> N f"Registering sub-controller {subctrl.name} with controller " + f"{self.name}." ) - self.add_sub_controller(subctrl.name, subctrl) + self.add_sub_controller(trim_ecat_name(subctrl.name), subctrl) def attribute_dict_generator( self, @@ -375,11 +376,73 @@ class CATioScanTimings: notification_period: float = 0.2 +# Keys that are valid inside each template field. +# {} / {n} / {n:02d} → numeric index (id, chain node, or chain position) +# {id} → the IOC root prefix (from the YAML `id:` field) +# {device_prefix} → rendered name of the parent device +# (node_prefix and module_prefix only) +# {node_prefix} → rendered name of the parent coupler/box +# (module_prefix only) +_VALID_TEMPLATE_KEYS: dict[str, frozenset[str]] = { + "device_prefix": frozenset({"id", "n"}), + "node_prefix": frozenset({"id", "n", "device_prefix"}), + "module_prefix": frozenset({"id", "n", "node_prefix", "device_prefix"}), +} + + +@dataclass +class CATioNameMappings: + """User-configurable name templates for EtherCAT subcontrollers. + + Every template is rendered with Python's :meth:`str.format` using: + + * ``{}`` / ``{n}`` / ``{n:02d}`` — numeric index for the node + (device id, chain-node index, or chain-position index). + * ``{id}`` — the IOC root prefix from the YAML ``id:`` field + (e.g. ``BL04I-EA-CATIO-01``).

Pin fastcs[epics]==0.15.0b4 (was >=0.15.0b3) and pvi==0.14.0b1 (was unpinned at 0.12.0); update uv.lock accordingly. - Remove 'title: CATio Demo' from fastcs.yaml; update schema.json so EpicsGUIOptions.title defaults to null rather than a required string, matching the upstream fastcs change. - Fix docstring and unit-test examples: BL04I-EA-ERIO-01 → BL04I-EA-E1RIO-01 (correct real-world device name). - Update fastcs-epics-ioc.md to reference CATioNameMappings templates instead of the removed ecat_name / get_type_name() implementation details. --- docs/explanations/fastcs-epics-ioc.md | 5 +---- pyproject.toml | 4 ++-- src/fastcs_catio/fastcs.yaml | 1 -

GroupLayout.INLINE on device controllers EtherCAT device sub-controllers are now given GroupLayout.INLINE when registered, so their attributes are rendered as an inline labeled Grid box on the server screen file rather than on a separate SubScreen file requiring a navigation button. 2. Hoist device-direct slave terminals to the server Slave terminal (module) sub-controllers that are direct children of a device node (i.e. attached directly on the EBus, not beneath a coupler/box) are now hoisted to the server alongside the existing coupler/box hoisting logic. This causes PVI to render them as SubScreen navigation buttons at the server-screen level, outside the device's inline Grid box. Slaves reached through an intermediate coupler/box are unaffected: they are registered with the coupler controller before the device-level hoisting check runs, so they continue to appear as navigation buttons within the coupler's own screen. --- src/fastcs_catio/catio_controller.py | 55 ++++++++++++++++++++-------- 1 file changed, 40 insertions(+), 15 deletions(-) diff --git a/src/fastcs_catio/catio_controller.py b/src/fastcs_catio/catio_controller.py index 27d4b2a..bdf16b7 100644 --- a/src/fastcs_catio/catio_controller.py +++ b/src/fastcs_catio/catio_controller.py @@ -738,11 +738,17 @@ async def get_subcontrollers_from_node( Once registered, each subcontroller is then initialised (attributes are created). - Couplers/boxes whose resolved path is a single segment (i.e. they have a - beamline-level PV prefix such as ``BL04I-EA-E1RIO-01``) are *hoisted*: - they are registered as direct sub-controllers of the server rather than - of the device, so that PVI can render them inline on the top-level screen - instead of nesting a Grid inside a SubScreen (which PVI forbids). + When a device node is encountered, its slave children are *hoisted* to the + server so that PVI renders them at the server-screen level rather than inside + the device's inline Grid box: + + - Couplers/boxes whose resolved path has exactly one segment (i.e. a + beamline-level PV prefix such as ``BL04I-EA-E1RIO-01``) are hoisted so + they get their own top-level screen file and index entry. + - Slave terminals (modules, e.g. ``MOD01``) are always hoisted so they + appear as SubScreen navigation buttons directly on the combined + server+device screen, rather than nested inside the device's Grid box. + - Multi-segment coupler/box paths stay as SubScreen children of the device. :param node: the tree node to extract available subcontrollers from. @@ -761,19 +767,38 @@ async def get_subcontrollers_from_node( for child in node.children: ctlr = await self.get_subcontrollers_from_node(child, current_path) assert (ctlr is not None) and (isinstance(ctlr, CATioController)) - # Hoist couplers/boxes with a root-level (1-segment) path to the - # server so they get their own top-level screen in the index. - # Multi-segment paths stay as SubScreen children of the device. - if ( - isinstance(node.data, IODevice) - and isinstance(child.data, IOSlave) - and child.data.category in (IONodeType.Coupler, IONodeType.Box) - and len(ctlr.path) == 1 - ): - hoisted.append(ctlr) + + # Hoist to the server (registered via self.add_sub_controller) so + # that they appear at the server-screen level rather than nested + # inside the device's inline Grid box: + # • Couplers/boxes with a root-level (1-segment) path get their + # own top-level screen and index entry. + # • Slave terminals (modules) which are directly attached to + # the device (via Ebus) become SubScreen navigation buttons + # directly on the server+device combined screen. + # Multi-segment coupler/box paths stay as SubScreen children of + # the device (they have their own PV prefix hierarchy). + if isinstance(node.data, IODevice) and isinstance(child.data, IOSlave): + if ( + child.data.category in (IONodeType.Coupler, IONodeType.Box) + and len(ctlr.path) == 1 + ) or child.data.category == IONodeType.Slave: + hoisted.append(ctlr) + else: + subcontrollers.append(ctlr) else: subcontrollers.append(ctlr) + # Set the layout of device controllers to INLINE so that they appear + # in the same screen file as the server and not in a separate SubScreen + # (which would be the default for a subcontroller). + if ( + isinstance(node.data, IOServer) + and isinstance(child.data, IODevice) + and child.data.category == IONodeType.Device + ): + ctlr.group_layout = GroupLayout.INLINE + logger.verbose( f"{len(subcontrollers) + len(hoisted)} subcontrollers were found for " f"{node.data.name} ({len(hoisted)} hoisted to server)."

Shorten attribute names at attribute-add time, where the controller's path (and therefore the available budget) is known: a new max_attribute_name_length helper computes the snake-case budget from pv_prefix_from_path + the EPICS limit (minus 4 for _RBV on AttrRW), and a new shorten_fastcs_name helper applies the existing abbreviation pass (preserving any trailing _idx suffix) only when the name exceeds the budget. CoE and symbol attribute paths both call it; the existing CoE collision detection runs on the post-shortening name. Add abbreviations for the words that show up in the failing EL3162 / EL3314 / ELM3704 CoE subindices (calibration, detection, offset, compensation, resistance, ...) so shortening produces readable names rather than truncating at word boundaries.
