=== | === Firmware devices on the Modbus broadcast address 0 === | ||
Bootloader | Bootloader allows you to download firmware to devices via Modbus address 0. To do this, the device must be the only device on the bus and must be in bootloader mode. | ||
=== | === Flashing several devices on the bus === | ||
It is possible to flash several devices connected to the bus. The devices must be set to bootloader mode and flashed separately with a non-broadcast Modbus address. Flashing devices with the same address is possible if only one of them is in the bootloader mode. The devices shall be flashed at a time. | |||
''' | '''Attention!''' The flashing of the devices in bootloader mode and of the same modbus address, or the flashing of multiple devices being in the bootloader mode at address 0 will not be performed; the existing firmware of the device will be ruined. |
