It sometimes occurred that the input data or output data of each pair of high
and low byte-address from PROFIBUS slave I/Os set as incorrect order in word
address block area. This is caused by the difference between PROFIBUS slave
I/Os venders specification and nv controller specification. To solve this
problem, with nV-Tool it is necessary to download the Byte-swap command
for the word address which is needed to be swapped.
Select the Slave I/O module parameter and chose the Tabs of Byte swap(IN)
or Byte swap(Out).Then select the address of word which you want to swap
the data order. After you select the data IN and Out ,Turn the MODE switch 3
ON (Refer 3.1.2) and Restart the PA912 with maintenance switch.
