API Breaks

  • Removes rarely-used TwinCAT state config PVs from TwinCATStateConfigOne
    that are also being removed from the IOCs.
    These are still available on the PLC itself.

    • delta
    • accl
    • dccl
    • locked
    • valid

  • Removes lens motors from TMOSpectrometer (SP1K4).

Features

  • EPICS motors now support setattr on their limits attribute.
    That is, you can do e.g. motor.limits = (0, 100) to set
    the low limit to 0 and the high limit to 100.
  • Adds a blank subclass of PPM, IM3L0, to allow for screens specific to this device that don't interfere with other PPM devices.
  • Adds a IM3L0.detailed.ui template to add embedded Keithley readout screen to detailed screen for IM3L0.
    IM3L0 has a Keithley multimeter added to it for higher-resolution readouts of its power meter.
  • ND (N-dimensional) TwinCAT states are now supported.
  • Updates supported positioner typhos templates to use the new row widget,
    TyphosPositionerRowWidget.

Device Updates

  • Updates limits for LaserTiming, LaserTimingCompensation, and LxtTtcExample from +/-10us to +/-100us.
  • Adds missing pump_state (:STATE_RBV) signal to PTMPLC.
  • Adds chin guard RTDs to FFMirrorZ in mirror.py.
  • LODCM: Adds the E1C pseudo-interface for moving only the first tower energy.
  • SmarAct: Adds signals for performing axis calibration and checking calibration status.
  • Adds laser destination 1 (LD1), where a diagnostics box is installed, to
    the Laser Beam Transport System (BTPS) state configuration. Updates
    overview and configuration screens to display LD1.
  • TwinCATInOutPositioner by default now uses 2 states as its name implies
    (excluding the "unknown" transition sate), with one representing the "out"
    state and one representing the "in" state.
  • XOffsetMirrorSwitch: adds cool_flow1, cool_flow2, and cool_press.
  • XOffsetMirrorSwitch gets component reordering.
  • Adds TIXEL Manipulator motors to LAMPMagneticBottle.
  • Adds twincat states and the ST3K4 automation switch to the SXR test absorber.
    This device is pcdsdevices.sxr_test_absorber.SxrTestAbsorber and is named ST1K4.
  • Includes the Fresnel Zone Plate (FZP) 3D states on the TMOSpectrometer device.
  • TMOSpectrometer (SP1K4): adds two new motors for solid attenuator and one for thorlabs lens x.
  • Add the following signals to BeckhoffAxis:
    • enc_count: the raw encoder count.
    • pos_diff: the distance between the readback and trajectory setpoint.
    • hardware_enable: an indicator for hardware enable signals, such as STO buttons.
  • Added new PVS to OpticsPitchNotepad for storing the MR2L3 channel-cut monochromator (CCM) pitch position setpoints for its two coatings.

New Devices

  • FDQ flow meter implemented in analog_signals.py.
  • PPMCOOL added to pim.py.
  • KBOMirrorChin added to mirror.py
  • SQR1Axis: A class representing a single axis of the tri-sphere motion system. It inherits
    from PVPositionerIsClose and includes attributes for setpoint, readback, actuation, and
    stopping the motion.
  • SQR1: A class representing the entire tri-sphere motion system. It is a Device that
    aggregates multiple SQR1Axis instances for each axis. It also includes methods for
    multi-axis movement and stopping the motion.
  • Includes example devices and components that correspond to
    lcls-plc-example-motion <https://github.com/pcdshub/lcls-plc-example-motion>_.
  • Adds BeckhoffAxisEPS, which has the new-style EPS PVs on its directional and power enables.
    These correspond to structured EPS logic on the PLC that can be inspected from higher level applications.

Bugfixes

  • KBOMirrorHE in mirror.py only has 1 flow sensor per mirror, so remove one.
  • Fixes an issue where the generic Motor factory function would not recognize devices with
    MCS2 in the PV name. These are now recognized as SmarAct devices.

Maintenance

  • Updates BtpsState comments and logic to help guide future port additions.
  • TwinCAT state devices now properly report that their state_velo
    should be visualized with 3 decimal places instead of with 0.
    This caused no issues in hutch-python and was patched as a bug in
    typhos, and is done for completeness here.
