Changelog¶

1.2.1 - January 9, 2025¶

✨ Improved¶

Clear the anti-flap lock in lvmecp dome reset.
Check if the drive is in error state before moving the dome.
Renamed registers dome_status[1|2] to drive_status[1|2].

🔧 Fixed¶

Wait for status to be output in lvmecp dome status before finishing the command.

⚙️ Engineering¶

Use pytest-timeout.

1.2.0 - January 7, 2025¶

🚀 New¶

#33 Add a mode to close the dome using only drive overcurrent to determine when the movement has completed.
#34 Implement emergency stop command, resetting e-stops, and prevent dome from opening if safety flags are active.

✨ Improved¶

Added PLC engineering mode status bits to the configuration file.
If the dome is moving when commanded to open/close, the movement will be stopped before actually open or close.
Daytime check for dome opening will be ignored if the PLC hardware or software overrides are active.
Improved the logging of Modbus messages.

🔧 Fixed¶

Fixed setting and resetting of the start time for the engineering mode.

1.1.0 - January 1, 2025¶

✨ Improved¶

#32 Major refactor of the Modbus and ModbusRegister classes. The main change is that the performance has been greatly improved, with Modbus.get_all() going from taking ~0.6 seconds to under 0.1. The register and coil blocks are now read completely, in chunks as large as the device will accept, as opposed to before, when we would read each variable with one read command (although the connection was not closed in between). Note that several methods and variables have been renamed; see the PR for details.

1.0.2 - December 27, 2024¶

✨ Improved¶

Report last time the heartbeat was set in the PLC in the status command.
Report timeout of the engineering mode.
Report ``last_heartbeat_set` as an ISO string.

1.0.1 - December 26, 2024¶

⚙️ Engineering¶

Bump CLU to 2.4.3.

🔧 Fixed¶

Do not command the dome to close during daytime if it is already closed.

1.0.0 - December 25, 2024¶

🚀 New¶

#29 Add a new engineering mode that can be used to bypass the heartbeat and to allow the dome to open during daytime. Part of RORR RID-025.
#30 Prevent the dome from opening during daytime. Close if daytime is detected. Part of RORR RID-025.
#31 Prevent the dome from opening multiple times in a short period of time. RORR RID-019.

✨ Improved¶

Add reporting of roll-off error state and allow resetting on error.
Prevent the PLC modules from running before the actor is ready.

🏷️ Changed¶

#28 Removed the automatic setting of the heartbeat variable. Added a heartbeat command that will be triggered by a heartbeat middleware.

🔧 Fixed¶

Restore GS3 status registers and fix addresses for roll-off lockout and error.

⚙️ Engineering¶

Updated workflows.

0.8.4 - November 3, 2024¶

✨ Improved¶

Add a lock for the status command to prevent multiple concurrent requests.

⚙️ Engineering¶

Use uv for packaging.

0.8.3 - September 7, 2024¶

🔧 Fixed¶

Fixed a bug that would make a module notification fail in some cases if its maskbit value was zero.

0.8.2 - August 19, 2024¶

✨ Improved¶

Fail open/close dome if the drive becomes disabled (usually due to the dome being stopped).

0.8.1 - July 23, 2024¶

🚀 New¶

Added rain sensor.

⚙️ Engineering¶

Format code using ruff.

0.8.0 - June 1, 2024¶

🚀 New¶

Allow not outputting the registers in status with --no-registers.
Use LVMActor as the base class for the ECP actor.

✨ Improved¶

Use dome_open and dome_closed modbus variables to determine the state of the roll-off.

0.7.0 - January 19, 2024¶

🚀 New¶

Added a cache to the registers with default timeout 0.5 second.
Modbus.read_group() calls Modbus.get_all() instead of reading individual registers sequentially. Since during a status all groups are read in quick succession, and with caching, this results in much faster status outputs.

✨ Improved¶

Moved the logic to lock a connection while in use to Modbus.connect() and disconnect() from the context manager.

🔧 Fixed¶

Use key modbus from configuration file to initialise a new Modbus instance when a configuration file path is passed.
Fixed output of status flags with value zero.

0.6.0 - January 13, 2024¶

🚀 Added¶

#26 Add heartbeat.

⚙️ Engineering¶

Pinned pymodbus to 3.6.2 due to test errors in 3.11.

0.5.1 - November 24, 2023¶

🔧 Fixed¶

Fixed cases in which the modbus lock could remain locked.

0.5.0 - November 5, 2023¶

🚀 New¶

Added support for lights.
Added support for O2 sensors.
Added support for HVAC controller.

🔧 Fixed¶

Additional improvments for dealing with PLC disconnections.

0.4.1 - August 25, 2023¶

🔧 Fixed¶

Attempt at fixing sporadic failures to read Modbus variable by introducing a retry loop.

⚙️ Engineering¶

Lint using ruff.

0.4.0 - July 9, 2023¶

🚀 New¶

Complete rewrite with dome and door functionality.

0.3.1 - May 23, 2022¶
