Communication via Modbus requires the interaction between a single Modbus client instance and multiple Modbus servers. This class provides the client implementation via a serial port.
- class PySide6.QtSerialBus.QModbusRtuSerialClient([parent=None])#
Constructs a serial Modbus client with the specified
- Return type:
Returns the amount of microseconds for the silent interval between two consecutive Modbus messages.
microseconds – int
Sets the amount of
microseconds for the silent interval between two consecutive Modbus messages. By default, the class implementation will use a pre-calculated value according to the Modbus specification. A active or running connection is not affected by such delay changes.
microseconds is set to -1 or
microseconds is less than the pre-calculated delay then this pre-calculated value is used as frame delay.
turnaroundDelay – int
Sets the amount of milliseconds for the silent interval between a Modbus broadcast and a consecutive Modbus messages to
turnaroundDelay. Typically the turnaround delay is in the range of
- Return type:
Returns the amount of milliseconds for the silent interval between a Modbus broadcast and a consecutive Modbus messages. The default value is set to
