Attaching Markers
Markers can be attached to PROFINET Coupler Units, NX Units, and terminal blocks on NX Units to
identify them.
The plastic markers made by OMRON are installed for the factory setting. The ID information can be

Commercially available markers can also be installed.
Replace the markers made by OMRON if you use commercially available markers now.
