v7.1.0 (2022-11-04)

Device Updates

• Allow BeckhoffAxis devices to report the NC error from the beckhoff PLC as part of the move status.

• Throw a clear error when the user tries to move a BeckhoffAxis that has the default velocity (zero), rather than failing silently.

Bugfixes

• Fix an issue where BeckhoffAxis devices would show error status after nearly any move, even those that ended normally.

• Fix _find_matching_range_indices method signature to include self. This was causing startup errors for the XRT mirrors.

Maintenance

• Update quadratic equation and soft limits for VLS focus mirror. These were no longer correct.

• Update example in docstring of LightpathMixin. The previous example was from an earlier implementation of the lightpath interface.

• Add argument to conftest.find_all_device_classes that allows specified device classes to be skipped. This is helpful for skipping interface classes that may not behave normally as independent devices.

• Set typhos>=2.4.0 in run_constrainted to make sure the typhos feature required for the template update is available.

• Four blade SXR solid attenuator (AT1K4 and AT2K2) screens have been updated to include all of the filters installed on each blade. It will also show the per-blade filters that the calculator will insert when “Apply Configuration” is clicked. The custom energy line edit will now remain visible regardless of the “Actual/Custom” Photon Energy selection.

• Adjust the BeckhoffAxis typhos templates to only show alarm state from hinted components instead of all components. This reduces the noise from an unresolved bug with alarm states that get stuck in a fake “major” state for monitors despite being cleared.

• Slightly adjust the sizing on the BeckhoffAxis detailed typhos template so that the errors can be read.

v7.0.1 (2022-10-26)

Device Updates

• Rename lens_pitch to lens_pitch to lens_pitch_up_down and lens_yaw to lens_yaw to lens_yaw_left_right.

Bugfixes

• When initializing the lightpath summary signal from a happi load, guard against bad input_branches or output_branches. This stops us from spamming the terminal when loading from a db without input_branches and output_branches.

• Fully removes LightpathItem from containers that subclassed it.

Contributors

• tongju12

• zllentz

v7.0.0 (2022-10-21)

API Changes

• Now compatible with and expecting lightpath v1.0.0 for lightpath support.

• Converted LightpathMixin to the new lightpath API, consolodating reporting into a single LightpathState Dataclass. The lightpath subscription system has also been simplified by using an AggregateSignal to monitor all relevant components.

• Overwrote the default move method for the CCMEnergy class to kill the PID loop at the end of each move (default). This should prevent the piezo motor from heating up and breaking vacuum or frying itself.

Features

• Made LCLSItem fully lightpath-compatible, to maintain backcompatibility of happi db, as well as added happi containers that work with the new lightpath interface. These containers allow input_branches and output_branches to be optional kwargs. This lets these containers work with devices that both do and do not implement the lightpath interface. In a future release the extra containers may be removed and should not be considered a permanent API.

• Added LightControl.ui screen for controlling fiber-lites.

• Added useful qmini embedded screen that’s been active in dev for over a year.

Device Updates

• Updated LightpathMixin implementation to the new API for all existing lightpath-active devices. This includes but is not limited to:

  • Mirrors

  • LODCMs

  • Attenuators

• Added an ns_delay_scan motor to the evr Trigger class that is convenient for scanning the delay in nanoseconds.

• Added the missing valve_position signal to ValveBase, making it available for all valve classes. This contains the valve’s state, e.g. “OPEN”, “CLOSED”, “MOVING”, “INVALID”.

• Made devices that use PVStateSignal like GateValve and PulsePicker report their enum states and write permissions in subscriptions for applications like typhos and lightpath.

• Updated pcdsdevices.laser.btps device classes following a PV rename.

• Updated pcdsdevices.laser.btps device classes to support the Laser Beam Transport Motion System (BTMS). In addition, this includes a module pcdsdevices.laser.btms_config which has utilities to represent the state of the BTS in a control system independent way and allows for motion verification and other sanity checks.

• Added two new thorlabs ZST213 into TMOSpectrometer, lens_pitch and lens_yaw.

• Renamed the valve signal named close_override to override_force_close for consistency with override_force_open, which is the corresponding “open” signal.

New Devices

• Added RohdeSchwarzPowerSupply class for controlling the Rohde Schwarz NGP800 power supply series.

• Added pcdsdevices.laser.btps.BtpsVGC a variant of the VGC class that included valve_position prior to this being added in ValveBase.

• Added HPI6030 in radiation.py, a device for reading out 6030 radiation data.

• Added Gen1VonHamos4Crystal and Gen1VonHamosCrystal to the spectrometer module to support the pre-ADS 4 crystal VonHamos.

Bugfixes

• Fixed an issue where various types of motors could have inconsistent limits metadata when the IOC or gateway doesn’t behave as expected.

• Fixed an issue where the UpdateComponent was incompatible with subscription decorators.

• Fixed PV typos in the BeckhoffSlits and PowerSlits typhos ui templates.

Maintenance

• Made some of the test motor simulations slightly more accurate.

• Mark test_presets as xfail because it has a race condition that is slowing down our development.

• Added an optional acr_status_suffix argument to BeamEnergyRequest that instantiates an alternate version of the class that waits on an ACR PV to know when the motion is done. This is a more suitable version of the class for step scans and a less suitable version of the class for fly scans.

New Devices

• Added KBOMirrorHEStates - a class for KBO mirrors with coating states and cooling.

• Added KBOMirrorStates - a class for KBO mirrors with coating states and no cooling.

Bugfixes

• Fixed the Stopper happi container definition.

• Removed unusable bunch_charge_2 signal from LCLS beam stats. This PV seems to contain a stale value that disagrees with bunch_charge and causes EPICS errors on certain hosts.

Maintenance

• Added a run constraint for pyqt to avoid latest while we work out testing failures.

Features

• adds .screen() method to BaseInterface, which opens a typhos screen

• adds AreaDetector specific .screen() method, which calls camViewer

• Add utilities for rearranging the order of components as seen by typhos. This can be helpful for classes that inherit components from other classes if they want to slot their new components in at specific places in the automatic typhos tree.

Device Updates

• Added “ref” signal to “BeamEnergyRequest” to track the energy reference PV.

• TwinCATStatePositioner has been updated due to underlying MultiDerivedSignal API changes.

• OpticsPitchNotepad - a class for storing pitch positions based on state in a notepad IOC for mr1l0, mr2l0, mr1l4, mr1l3, and mr2l3.

Bugfixes

• Fix calls to ipm_screen.

• Fix an issue where Beckhoff motion error reset signals could not be set twice in the same session.

• Fix an issue where the TMO Spectrometer and the HXRSSS would spam errors when loaded in lightpath.

Maintenance

• Ran pre-commit on all files in the repository, except the ones where it causes issues. Update the CI to require these checks to pass. (passive update, this is the new pcds-ci-helpers master). Notable changes were related to import sorting and removal of trailing whitespace.

v5.2.0 (2022-03-31)

Features

• Added a post_elog_status method to the BaseInterface class, which posts to the registered primary elog if it exists.

• Added a function for posting ophyd object status (and lists of objects) to the ELog as html.

• Added new AggregateSignal variant MultiDerivedSignal. With a list of signal names and a calculation function, it is now possible to create a new signal derived from the values of the provided signals. For example, if a hutch has many temperature sensors - each with their own corresponding EpicsSignal instance - a signal that shows the maximum value from all of those temperatures would be easy to implement.

• Added the scale keyword argument to tweak() method, allowing the user to pick the initial step size.

Device Updates

• Added the Y axis to the KBOMirror status printout

• TwinCAT state devices now have a top-level “state_velo” summary signal. This can be used to view the highest speed of all the configured state speeds, and it can also be used to do a bulk edit. These are stored per state destination in the IOC.

• Added a biological parent attribute to GroupDevice, for tracking parents without alerting stage() methods

• Added the current monitoring PV to pcdsdevices.pump.PTMPLC.

• Allow for user offsets to TMO Spectrometer motors.

• Commented out the GasNeedleTheta motor for 3/22 LAMPMBES configuration.

New Devices

• Adds a new class to interface with the LAMP motion configuration for LV17.

Bugfixes

• EpicsSignalEditMD will be more lenient for cases where we have unset metadata strings (“Invalid”) from TwinCAT. This fixes recent issues involving terminal spam and failure to update enum strings for devices like the solid attenuators.

• EpicsSignalEditMD will not send metadata updates until all composite signals have connected and updated us with their values.

• Fix SL1K2 target count (2 states + out instead of default).

• Fixed mr1l0_homs and mr2l0_homs state counts in TwinCATMirrorStripe. This should be set to 2 for mr1l0 (B4C, B4C/Ni) and mr2l0 (B4C, Ni).

Maintenance

• detailed_tree.ui was vendored from typhos. The default attenuator screens AT2L0, AT1K4, and AT2K2 will now default to detailed_tree.ui.

Contributors

• zllentz

v5.0.1 (2021-11-19)

Bugfixes

• CCM status representation fixed in certain situations. (#908)

• Exceptions will no longer be raised when generating device status representations. (#909)

Contributors

• klauer

v5.0.0 (2021-11-15)

API Changes

• TwinCATStateConfigAll has been removed. This was considered an internal API.

• isum components have been renamed to sum in IPM detector classes.

• The motor components for PIM classes have been shortened by removing _motor from their names (e.g. zoom_motor is now zoom).

• Switch the target PVs for BeamEnergyRequest from e.g. “XPP:USR:MCC:EPHOT” to e.g. “XPP:USR:MCC:EPHOT:SET1”, “RIX:USR:MCC:EPHOTK:SET1”.

Features

• EpicsSignalEditMD and EpicsSignalROEditMD now allow for overriding of enumeration strings (enum_strs) by way of a static list of strings (enum_strs kwarg) or a list of signal attribute names (enum_attrs kwarg).

• Update TwinCATStatePositioner to have a configurable and variable number of state configuration PVs. These are the structures that allow you to check and change state setpoints, deltas, velocities, etc. This is implemented through the new TwinCATStateConfigDynamic class.

• Increase the maximum number of connected state configuration records to match the current motion library limit (9)

Device Updates

• Using the new TwinCATStateConfigDynamic mechanisms and the UpdateComponent, update the following classes to contain exactly the correct number of twincat configuration states in their component state records. Note that the number of states here does not include the “Unknown” or “Moving” state associated with index 0. A device with n states will have typically have 1 out state and n-1 target states by this count, and the EPICS record will have n+1 possible enum values. - ArrivalTimeMonitor (6) - AttenuatorSXR_Ladder (9) - AT2L0 (2) - FEESolidAttenuatorBlade (2) - LaserInCoupling (2) - PPM (4) - ReflaserL2SI (2) - WavefrontSensorTarget (6) - XPIM (4)

• The default theta0 values for CCM objects has been changed from 14.9792 to 15.1027.

• IPM objects now have short aliases for their motors (ty, dx, dy).

• Reorganized the sample delivery Selector class to be composed of two Sensiron devices instead of a flat collection of PVs.

• In VGC_2S, allow for the user to change the at_vac setpoint value for upstream and downstream gauges separately.

• Add the user_enable signal (bUserEnable) to the BeckhoffAxisPLC class. This is a signal that allows the user to unilaterally disable a running motor’s power. When enabled, it is up to the controller whether or not to actually power the motor, but when disabled the power will be shut off.

• Add the ability for BeamEnergyRequest to write to PVs for either the K or the L line and for either bunch 1 or bunch 2 in two bunch mode.

New Devices

• Add TM2K2, a variant of the ArrivalTimeMonitor class that has an extra state (7). The real TM2K2 has one extra target holder compared to the standard ArrivalTimeMonitor.

• BeckhoffAxis_Pre140 has been added to support versions of lcls-twincat-motion prior to v1.4.0. This has been aliased to OldBeckhoffAxis for backcompat.

• Created Bronkhorst and Sensiron flow meter devices for sample delivery.

• Added the crix_motion.VLSOptics Device, which contains calculated axes for the VLS optical components. The rotation state of these crystals is approximated by a best-fit 2nd order polynomial.

• Add VRCClsLS, a class for gate valves with control and closed limit switch readback.

Bugfixes

• Fix subtle bugs related to the UpdateComponent and using copy vs deepcopy. This was needed to make the dynamic state classes easy to customize.

• Add an extra error state in UpdateComponent for when you’ve made a typo in your component name. Previously this would give a confusing NameError.

• In the LODCM “inverse” calculations, return a NaN energy instead of raising an exception when there is a problem determining the crystal orientation. This prevents the calculated value from going stale when it has become invalid, and it prevents logger spam when this is called in the pseudopositioner update position callback.

Maintenance

• Add various missing docstrings and type annotations.

• Tab whitelists have been cut down to make things simpler for non-expert users.

Maintenance

• Removed prototype-grade documentation helpers in favor of those in ophyd.docs

• Added similar find_all_callables for the purposes of documentation and testing.

v4.8.0 (2021-09-28)

Features

• Add GroupDevice: A device that is a group of components that will act independently. This has some performance improvements and small optimizations for when we expect the different subdevices to act fully independently.

• Add a status method to BaseInterface to return the device’s status string. This is useful for recording device status in the elog.

• Add typhos templates for BeckhoffSlits and PowerSlits using existing elements from their normal pydm screens.

Device Updates

• The following devices have become group devices: - Acromag - ArrivalTimeMonitor - BaseGon - BeckhoffJet - BeckhoffJetManipulator - BeckhoffJetSlits - CCM - CrystalTower1 - CrystalTower2 - CVMI - DiagnosticTower - ExitSlits - FFMirror - FlowIntegrator - GasManifold - ICT - Injector - IPIMB - IPMDiode - IPMMotion - Kappa - KBOMirror - KMono - KTOF - LAMP - LAMPMagneticBottle - LaserInCoupling - LCLS2ImagerBase - LODCM - LODCMEnergyC - LODCMEnergySi - Mono - MPODApalisModule - MRCO - OffsetMirror - PCM - PIM - PulsePickerInOut - ReflaserL2SI - RTDSBase - SamPhi - Selector - SlitsBase - StateRecordPositionerBase - VonHamosCrystal - VonHamosFE - Wave8 - WaveFrontSensorTarget - XOffsetMirror - XYZStage

• Clean up pmgr loading on the IMS class.

• Edit stage/unstage on PIMY to be compatible with GroupDevice.

• Edit stage/unstage and the class definition on SlitsBase to be compatible with GroupDevice

• Change CCM from a InOutPositioner to a normal device with a LightpathMixin interface. Being a positioner that contained a bunch of other positioners, methods like move were extremely ambiguous and confusing. The insert and remove methods are re-implemented as they are useful enough to keep.

• Split CCMCalc into CCMEnergy and CCMEnergyWithVernier to make the code easier to follow

• Remove unused CCMCalc feature to move to wavelength or theta to make the code simpler to debug

• Add aliases to the CCM for each of the motors.

• Adjust the CCM status to be identical to that from the old python code.

• Add functions and PVs to kill and home the CCM alio

• Calculate intermediate quantities in the CCM energy calc and make them available in both the status and as read-only signals.

• EpicsMotorInterface subclasses will no longer spam logger errors and warnings about alarm issues encountered by other users. These log messages will only be shown if they were the result of moves in the current session. Note that this log filtering assumes that all epics motors will have unique ophyd names.

• Added GFS fault setpoint, GCC, PIP auto-on and countdown timer

• Switch the CCM energy devices to use user PVs as the canonical source of calculation constants. This allows the constants to be consistent between sessions and keeps different sessions in sync with each other.

• Add CCM.energy.set_current_position utility for adjusting the CCM theta0 offset in order to synchronize the calculation with a known photon energy values.

New Devices

• TMO Fresnel Photon Spectrometer Motion components class, TMOSpectrometer

Bugfixes

• Fix some race conditions in FuncPositioner

• Fix a race condition in schedule_task that could cause a task to never be run

• Add a timeout parameter to IMS.reinitialize, and set it as the default arg for use in the stage method, which is run during scans. This avoids a bug where the stage method could hang forever instead of erroring out, halting a scan in its tracks.

• Fix an issue where epics motors could time out on the getting of the egu property, which was causing issues with the displaying of device status.

Maintenance

• Move PVStateSignal from state.py to signal.py to avoid a circular import

• Make the tests importable and runnable on Windows

• Require Python 3.9 for type annotations

• Make pmgr optional, but if installed make sure it has a compatible version.

• Added the pcds typhos templates from typhos.

New Devices

• Add classes for controlling the new apalis mpods. The new apalis mpod PVs differ from previous model PVs and needed new classes to accommodate those changes. Features:

v4.6.0 (2021-07-09)

Features

• Add pmgr support to the IMS class! There are three new methods on IMS for interacting with pmgr: configure, get_configuration, and find_configuration.

Device Updates

• User changes to offset/dir on python or UI level to MRCO motion have been disabled.

• Add the veto_device signal (:VETO_DEVICE_RBV) to the VFS class.

• XYGridStage now uses one file per sample instead of one giant file for all samples, and it writes to these files less often. This speeds up operations. Various additional improvements to the class.

New Devices

• Add special IM2K0 device for the new configuration of IM2K0, where we swapped its XTES style camera setup for a L2SI style camera setup.

Bugfixes

• Fix an issue where DelayBase subclasses could spam the terminal at startup if we load too many devices at once.

• Fix a typo in the KBO DS Bender RMS PV.

• Fix issue where motor presets would not load until the first access of the presets object.

v4.5.0 (2021-06-03)

Features

• Add UpdateComponent, a component class to update component args in subclasses.

Device Updates

• Update kmono threshold for showing beam passing in lightpath

• Rename PPSStopperL2SI to PPSStopper2PV and generalize to all PPS stoppers whose states are determined by the combination of two PVs. The old name and old defaults are retained for backcompatibility and have not yet been deprecated. This was done to support the PVs for ST1K2 which do not follow any existing pattern.

• Set various beamline component motor offset signals to read-only, using the new BeckhoffAxisNoOffset class, to prevent accidental changes. These are static components that have no need for this level of customization, which tends to just cause confusion.

New Devices

• MRCO motion class for MRCO IP1 endstation in TMO.

• Added a class for the RIX ladder-style solid attenuator AT2K2.

• Add BeckhoffAxisNoOffset, a varition on BeckhoffAxis that uses UpdateComponent to remove write access on the user offset signals.

Bugfixes

• Fix issue where BeckhoffSlits devices could show metadata errors on startup by cleaning up the done moving handling. This would typically spam the terminal in cases where we were making large numbers of PV connections in the session at once, such as at the start of a hutch-python load.

Contributors

• cristinasewell

v4.3.0 (2021-04-02)

API Changes

• Deprecate pcdsdevices.component in favor of pcdsdevices.device to avoid circular imports and to more closely mirror the structure of ophyd.

Features

• Fix issue where Newport motors would not show units in their status prints.

• Fix issue where SyncAxis was not compatible with PseudoPositioners as its synchronized “real” motors.

• Fix an issue where calling set_current_position on certain motors would cause the ipython session to freeze, leaving the motor in the set state instead of bringing it back to the use state.

• Hacky workaround for IMS motor part number strings being unable to be read through pyepics when they contain invalid utf-8 characters.

• Fix issue where Newport user_readback had incorrect metadata.

• UnitConversionDerivedSignal will now pass through the units keyword argument in its metadata (SUB_META or 'meta') callbacks. It will be included even if the original signal did not include units in metadata callbacks. (#767)

• Fix an issue where various special Signal classes had their kinds improperly reported as “hinted”.

Maintenance

v4.1.0 (2021-02-10)

API Changes

• Update twincat motors to use the correct homing PV. This is an alternative PV to the normal motor record PVs for IOC/PLC management reasons. It is possible that this will break devices that have not updated to the latest motion PLC library.

API Changes

• The calculations for alio_to_theta and theta_to_alio in ccm.py have been reverted to the old calculations.

• User-facing move functions will not be able to catch the LimitError exception. These interactive methods are not meant to be used in scans, as that is the role of bluesky.

Features

• pcdsdevices.attenuator.AT2L0 now has a textual representation of filter status, and supports the move interface by way of transmission values.

• SyncAxes has been adjusted to support scalar-valued pseudopositioners, allowing for more complex devices to be kept in lock-step motion.

• PseudoPositioner position tuples, when of length 1, now support casting to floating point, meaning they can be used in many functions which only support floating point values.

• Adds TimeToolDelay, an alias for DelayNewport with additional contextual information and room for future development.

• Add LaserInCoupling device for TMO.

• Add ArrivalTimeMonitor device for TMO.

• Add ReflaserL2SI device for TMO.

• Fixed a typo in a ValueError exception in pcdsdevices.state.StatePositioner.check_value().

• A read-only PV was erroneously marked as read-write in pcdsdevices.gauge.GaugeSerialGPI, component autozero. All other devices were audited, finding no other RBV-related read-only items.

• The direction of LaserTiming (lxt) was inverted and is now fixed.

• Allow setting of EpicsMotor limits when unset in the motor record (i.e., (0, 0)) when using EpicsMotorInterface.

v2.11.0 (2020-09-21)

API Changes

• BaseInterface no longer inherits from ophyd.OphydObject.

• The order of multiple inheritance for many devices using the LCLS-enhanced BaseInterface, MvInterface, and FltMvInterface has been changed.

• Added pcdsdevices.interface.TabCompletionHelperClass to help hold tab completion information state and also allow for tab-completion customization on a per-instance level.

• Presets add_hutch (and all similar add_*) methods no longer require a position. When unspecified, the current position is used.

Features

• For pcdsdevices.pseudopos.DelayBase, added set_current_position() and its related component user_offset, allowing for custom offsets.

• Epics motors can now have local limits updated per-session, rather than only having the option of the EPICS limits. Setting limits attributes will update the python limits, putting to the limits PVs will update the limits PVs.

• Add PVPositionerDone, a setpoint-only PVPositioner class that is done moving immediately. This is not much more useful than just using a PV, but it is compatibile with pseudopositioners and has a built-in filter for ignoring small moves.

• Moves using mv and umv will log their moves at info level for interactive use to keep track of the sessions.

• Add user_offset to UnitConversionDerivedSignal, allowing for an arbitrary user offset in user-facing units.

• Add user_offset signal to the pcdsdevices.lxe.LaserTiming, by way of UnitConversionDerivedSignal, offset support.

Device Updates

• CCM energy limited to the range of 4 to 25 keV

• Fix bug in PulsePickerInOut where it would grab only the first section of of the PV instead of the first two

• Tweak will feel less “janky” now and give useful feedback.

• Tweak now accepts + and - as valid inputs for changing the step size.

• Tweak properly clears lines between prints.

• Fix issue where putting to the limits property would update live PVs, contrary to the behavior of all other limits attributes in ophyd.

• Fix issue where doing a getattr on the limits properties would fetch live PVs, which can cause slowdowns and instabilities.

• Preset methods are now visible when not in engineering mode. (#576)

• Rework BeamEnergyPositioner to be setpoint-only to work properly with the behavior of the energy PVs.

• FltMvPositioner.wm will now return numeric values if the position value is a tuple. This value is the first element of the tuple, which for pseudo positioners is a value that can be passed into move and have it do the right thing. This resolves consistency issues and fixes bugs where mvr and umvr would fail.

• Fixed a race condition in the EventSequencer device’s status objects. Waiting on these statuses will now be more reliable.

• Fix issue where converting units could incur time penalties of up to 7 seconds. This should take around 10ms now.

• Fix bug on beam request where you could not override the tolerance via init kwarg, despite docstring’s indication.

Maintenance

• Establish DOC conventions for accumulating release notes from every pull request.

• Tweak refactored for maintainability.

• Use more of the built-in ophyd mechanisms for limits rather than relying on local overrides.
