• Documentation:

  • if you’re planning to develop start w/ reading “CONTRIBUTING.rst”, otherwise either

  • read HVL CCB documentation at RTD, or

  • install Sphinx and sphinx_rtd_theme Python packages and locally build docs on Windows in git-bash by running:

    $ ./make.sh docs

    from a shell with Make installed by running:

    $ make docs

    The target index HTML (“docs/_build/html/index.html”) will open automatically in your Web browser.

Features

Manage experiments with ExperimentManager instance controlling one or more of the following devices:

• a MBW973 SF6 Analyzer / dew point mirror over a serial connection (COM-ports)

• a LabJack (T7-PRO) device using a LabJack LJM Library for communication

• a Schneider Electric ILS2T stepper motor drive over Modbus TCP

• a Elektro-Automatik PSI9000 DC power supply using VISA over TCP for communication

• a Rhode & Schwarz RTO 1024 oscilloscope using VISA interface over TCP::INSTR

• a state-of-the-art HVL in-house Supercube device variants using an OPC UA client

• a Heinzinger Digital Interface I/II and a Heinzinger PNC power supply over a serial connection

• a passively Q-switched Pulsed Laser and a laser attenuator from CryLas over a serial connection

• a Newport SMC100PP single axis motion controller for 2-phase stepper motors over a serial connection

• a Pfeiffer TPG controller (TPG 25x, TPG 26x and TPG 36x) for Compact pressure Gauges

• a SST Luminox Oxygen sensor device controller over a serial connection

History

0.4.0 (2020-07-16)

• Significantly improved new Supercube device controller:

  • more robust error-handling,

  • status polling with generic Poller helper,

  • messages and status boards.

  • tested with a physical device,

• Improved OPC UA client wrapper, with better error handling, incl. re-tries on concurrent.futures.TimeoutError.

• SST Luminox Oxygen sensor device controller.

• Backward-incompatible changes:

  • CommunicationProtocol.access_lock has changed type from threading.Lock to threading.RLock.

  • ILS2T.relative_step and ILS2T.absolute_position are now called, respectively, ILS2T.write_relative_step and ILS2T.write_absolute_position.

• Minor bugfixes and improvements:

  • fix use of max resolution in Labjack.set_ain_resolution(),

  • resolve ILS2T devices relative and absolute position setters race condition,

  • added acoustic horn function in the 2015 Supercube.

• Toolchain changes:

  • add Python 3.8 support,

  • drop pytest-runner support,

  • ensure compatibility with labjack_ljm 2019 version library.

0.3.5 (2020-02-18)

• Fix issue with reading integers from LabJack LJM Library (device’s product ID, serial number etc.)

• Fix development requirements specification (tox version).

0.3.4 (2019-12-20)

• New devices using serial connection:

  • Heinzinger Digital Interface I/II and a Heinzinger PNC power supply

  • Q-switched Pulsed Laser and a laser attenuator from CryLas

  • Newport SMC100PP single axis motion controller for 2-phase stepper motors

  • Pfeiffer TPG controller (TPG 25x, TPG 26x and TPG 36x) for Compact pressure Gauges

• PEP 561 compatibility and related corrections for static type checking (now in CI)

• Refactorings:

  • Protected non-thread safe read and write in communication protocols

  • Device sequence mixin: start/stop, add/rm and lookup

  • .format() to f-strings

  • more enumerations and a quite some improvements of existing code

• Improved error docstrings (:raises: annotations) and extended tests for errors.

0.3.3 (2019-05-08)

• Use PyPI labjack-ljm (no external dependencies)

0.3.2 (2019-05-08)

• INSTALLATION.rst with LJMPython prerequisite info

0.3.1 (2019-05-02)

• readthedocs.org support

0.3 (2019-05-02)

• Prevent an automatic close of VISA connection when not used.

• Rhode & Schwarz RTO 1024 oscilloscope using VISA interface over TCP::INSTR.

• Extended tests incl. messages sent to devices.

• Added Supercube device using an OPC UA client

• Added Supercube 2015 device using an OPC UA client (for interfacing with old system version)

0.2.1 (2019-04-01)

• Fix issue with LJMPython not being installed automatically with setuptools.

0.2.0 (2019-03-31)

• LabJack LJM Library communication wrapper and LabJack device.

• Modbus TCP communication protocol.

• Schneider Electric ILS2T stepper motor drive device.

• Elektro-Automatik PSI9000 current source device and VISA communication wrapper.

• Separate configuration classes for communication protocols and devices.

• Simple experiment manager class.

0.1.0 (2019-02-06)
