<modbusSession>.ReadFloat	Reads one or more single-precision floats from a Modbus slave, starting at a specific address.
<modbusSession>.ReadRegister	Reads one or more registers from a Modbus slave, starting at a specific address.
New in version 2024 <modbusSession>.SendRawFrame	Sends a raw frame to a Modbus slave. This enables communication with devices that do not strictly comply with the Modbus standard.
