Endian Swap
By default EtherNet/IP uses the little-endian format.
Big-endian
The big-endian format places the most significant byte of the data at the byte with the lowest
memory address.
Little-endian
The little-endian format places the least significant byte of the data at the byte with the lowest
memory address.
To convert between big-endian and little-endian you must reverse the byte order.
