Cyclic data transmission is divided into a bit and a word area. 
CC-Link IE Field Basic is based on stations, whereby each station incorporates 64 bits and 
32 words. 
The BNI CIB module can be configured for between 2 and 5 stations and thereby offers various 
process data sizes of 8 to 32 bytes. The bit area is the same for all station configurations. In 
addition to the status information, the word area also contains the IO-Link process data, the 
size of which varies with the configuration. The process data size applies to both input and 
output data. A word is filled with two bytes.
