Changelog¶

1.2.0 - May 30, 2024¶

🚀 New¶

Added a new convert module with function to convert register unsigned 16-bit integers to different data types.

1.1.0 - September 12, 2023¶

🚀 New¶

Allow to set the connection timeout when initialising Drift.

⚙️ Engineering¶

Lint with ruff.
Update codebase to work with pymodbus 3.5+.

1.0.2 - March 10, 2023¶

🔧 Fixed¶

Pin pymodbus<3.2.0. This versions removes the protocol attribute in AsyncioModbusTcpClient and breaks drift. It will be fixed in a future version.

1.0.1 - December 24, 2022¶

🔧 Fixed¶

Fixed reconnection. pymodbus now set the host to None after the transport closes, so it needs to be rested before reconnecting.

1.0.0 - December 24, 2022¶

🚀 New¶

Dropped Python 3.7 and add support for 3.11 with pymodbus>=3.0.0.

0.4.5 - November 9, 2022¶

🔧 Fixed¶

Release lock if connection fail in Drift.__aenter__.

0.4.4 - May 25, 2022¶

🚀 New¶

Drift() can now be initialised with lock=False which will disable the locking of the client while the context manager is used. In this mode, multiple concurrent connections to the client are allowed.
Added Drift.read_devices() which allows reading multiple devices concurrently with only one connection to the client.
Drift.devices returns a list of all connected devices.

✨ Improved¶

Module does not require to pass a number of channels anymore. In fact the number of channels is never used so it may be deprecated in the future.
Add poetry dependency groups.

0.4.3 - May 13, 2022¶

🎨 Engineering¶

Use latest pre-release version of poetry core, do not require setuptools, and test for 3.10.

0.4.2 - May 11, 2022¶

✨ Improved¶

Drift.from_config() now accepts keyword arguments that are passed to __init__().

0.4.1 - February 4, 2022¶

🚀 New¶

#9 Device now accepts a data_type argument that follows the same format as the struct module and allows to cast the read raw value from unsigned 16-bit integer to a different type, before passing it to an adaptor.

0.4.0 - December 14, 2021¶

💥 Breaking changes¶

Device addresses now must include the offset (i.e., 40001 is not subtracted).

🚀 New¶

Add proportional adaptor.

0.3.0 - October 12, 2021¶

🚀 New¶

Add the option to add an offset to the read value after applying the adaptor.

✨ Improved¶

Updated documentation theme to furo.

🔧 Fixed¶

Fix case when linear adaptor range does not start at zero.

0.2.5 - August 1, 2021¶

✨ Improved¶

Added gain parameter to voltage adaptor.

0.2.4 - July 27, 2021¶

🔧 Fixed¶

#7 If the connection to the client fails, release the lock immediately.

0.2.3 - July 15, 2021¶

🔧 Fixed¶

#5 Fixed an error that would happen when switching the first (channel 0) bit in a holding register. In that case the code would just set the entire register, ignoring the other set bits.

0.2.2 - May 18, 2021¶

🔧 Fixed¶

Fix a nasty bug that would force all relays to be of mode coil even if its module has been defined as a holding_register. Also, fix the writing of bits when channel is set in a holding register.

0.2.1 - February 23, 2021¶

🔧 Fixed¶

Add a lock to the connection context manager to prevent multiple simultaneous connections disconnecting the client.

0.2.0 - February 22, 2021¶

🚀 New¶

Major rewrite of how addresses, channels, and modes work.
Rename E+E adaptors and add rtd10 adaptor.
Add voltage, pwd, flow, and linear adaptors.

🔧 Cleanup¶

#4 Add typing and use Black formatting.

0.1.5 - October 10, 2020¶

🔧 Fixed¶

#3 Fix import of AsyncioModbusTcpClient when using pymodbus>=2.4.0.

0.1.4 - August 19, 2020¶

🔧 Cleanup¶

Do not require extra dev for sdsstools.

0.1.3 July 30, 2020¶

🚀 New¶

Add Drift.read alias to Drift.read_device.

🔧 Fixed¶

Fix Drift.get_device not working for case-insensitive devices.

0.1.2 - July 29, 20202¶

🔧 Cleanup¶

Relax sdsstools version to allow jaeger to bump the minimum version.

0.1.1 - July 19, 2020¶

🔧 Cleanup¶

Updated release workflow.
Expose exceptions.

0.1.0 - July 19, 2020¶

🚀 New¶

Initial version, based on jaeger’s code.
Added testing suite.
Added documentation.
