After I used interbus-Profinet coupler, byte sway happened, but there is no parameter of byte swap on it.
So, I want to choose profinet-profinet couplet to have the byte swayp parameter.
When doing byte swap, byte swap should be separated.
For example, there is combination of four words like 2 byte + 2 byte + 2 byte+2 byte.
First 2 byte has the parameter of byte swap.
Second 2 byte has the parameter of byte swap.
Thrid 2 byte has the parameter of byte swap
Fourth 2 byte has the parameter of byte swap.
The anybus can not perform any byte swapping. If any byte swapping occurs it is most likely due the the protocols supporting different endiness.
