ordinarily. Expectation is the case of which Slave I/O transfer its data to
PROFIBUS as little-endian order with word-type. Data transferring type is
depend on the Slave I/O's manufacturer's specification, and At that case User
is needed to send byte-swap command by nv-tool (Detail is described at

○ ：Order in the TC-net common area is correct .and No need for
additional setting.
□：Order in the TC-net common area is incorrect.(Byte-swap is
occurs) and User is needs for additional setting by nv-tool.
×： Order in the TC-net common area is incorrect.(Byte-swap is
occurs). and User is needs to set PA912 as byte-swap mode.
