Firmware Update in a System with Several Sunny Islands
In a system with several Sunny Island devices, the firmware is only updated on the master. If the master
detects that a slave has a different firmware version, it transmits its firmware to the slave and makes
sure that all Sunny Island devices within a system operate with the identical firmware version.
While the master updates the slave(s), the slave(s)
display(s) the message shown here.
At the same time, the message shown here appears on
the master.
After the firmware update, the parameters are
downloaded onto the slave devices.
Wait until all slave processes have terminated, and until
this display appears on the slave devices' screens.
Reset after a successful update
After the update has been successfully completed a reset is enforced in order that the
changes become effective. After the reset, the master device remains in standby mode.

If you have carried out a firmware update in which the number before the period in the
firmware version has changed, it is advisable to start QCG and to perform all settings
anew.
