Scanning devices on the bus
Usually, an installation includes several slave devices on one RS-485 bus inside a panel or in the field. Each device has an address that the user can change. During installation, the addresses of slave devices are written down from the device casing and manually entered into the master configuration. This is not very convenient. To simplify device configuration, there is a bus scanning function. It was available in the Wiren Board controller even before the Quick Modbus extension was released. With the release of the extension, the ability to quickly scan the bus without waiting for a timeout for each non-existent address was added.
