NX-series PROFINET Coupler Unit User’s Manual (W623)
The IO allocation display area includes the following information.
Padding is sometimes required in the IO allocation to fill remaining bits within an incomplete byte of
data. This is done automatically to ensure whole bytes are used for data exchange.
The PROFINET Coupler Unit only supports little endian. It is recommended to select an IO Control-
ler/PLC which supports function blocks to swap from little-endian to big-endian. Please refer to third
party IO Controller Operation manual how to use the swap function blocks.

on page 9-27 for more information.
Bit Offset
The consecutive order of bits assigned based on the size of each port accounting for any
necessary padding (see below for padding details).
Size
Each item in the port area has a specific data size and this determines the bit offset and the
data input/output total size.
IO Data Size
The summary of the input/output bytes required to accommodate all port items previously
configured.
Output to File
Clicking Output to File will generate a zip file that includes an .xsl and .xml file.
Opening the .xml file in a browser will display a table overview of the IO allocation.
