Precautions for Correct Use
Allocate the process input data from and process output data to IO-Link devices consecutively
starting from data 01. A setting error will occur if the data allocations are not consecutive or are
in reverse order.
A Slave Initialization Error occurs in the Communications Coupler Unit.
Examples: When the sequence is reversed, when allocations are not consecutive, and when
there is port 1 data for port 2.
• To save the I/O data size for unused ports, delete the I/O entries for the unused ports from
the I/O entry mapping list.
