(5) Some Master devices, such as the Mitsubishi A1SJ71PB92D
Programmable Controller will require that this data be sent to the
inverter in a "byte-swapped" configuration. In this case, the position of
the high-order byte and the low-order byte are switched in the data
string.

(6) These 6 words (described in following subsections) are how the
network master and slave (the option unit) communicate via the
PROFIBUS-DP protocol. It is through this addressing scheme that the
sender indicates which data word within the drive is being accessed
and what that access is.
(7) This option unit does not support any other manufacturer-specific
messages/parameters.
