5.3.3 Points to note

Only when the contents of the command request (request for changing the
inverter setting: PKW, HSW, STW/ECW) from the master changed, the
inverter processes the request. If the contents of the command request
are identical with those of the last request, the inverter does not process
the request. (The received request is cleared.)
For instance, while the master keeps sending the "network operation
mode enabled" command, changing the mode to the PU operation mode
with switchover function does not allow the "network operation mode
enabled" command to be executed due to the same contents as that
sent last time. Therefore, the operation mode remains the PU operation
mode without changing to the network operation mode.
In this case, send another command as "PU operation mode enabled"
from the master once, then send the "network operation mode enabled"
command again.
