PySide6.QtSerialBus¶

Detailed Description¶

The Qt Serial Bus API provides classes and functions to access the various industrial serial buses and protocols, such as CAN, ModBus, and others.

To include the definitions of modules classes, use the following directive:

import PySide6.QtSerialBus

Qt CAN Bus

Qt Modbus

The QtSerialBus module exports the following logging categories:

Logging Category	Description
qt.canbus	Enables standard logging inside the Qt CAN Bus classes
qt.canbus.plugins	Enables low level logging inside the Qt CAN Bus plugin classes. To set logging for a specific plugin, use `qt.canbus.plugins.pluginname`, e.g. `qt.canbus.plugins.socketcan`. `qt.canbus.plugins*` affects all plugins.
qt.modbus	Enables standard logging inside the Qt Modbus classes
qt.modbus.lowlevel	Enables low level logging including individual packet content inside the Qt Modbus classes

Logging categories can be used to enable additional warning and debug output for QtSerialBus.

A quick way to enable all Qt Modbus logging is to add the following line:

QLoggingCategory.setFilterRules("qt.modbus* = true")
