In Modbus communication, polling is a technique used by the master device to retrieve data from slave devices. The master device sends a request to the slave device, which responds with the requested data. The master device then polls the slave device at regular intervals to retrieve updated data. This process is essential in industrial automation, as it enables the master device to monitor and control the slave devices in real-time.
