Precautions for Correct Use
• If you do not use tag data link communications but want to input and output data with an NX
Unit, use this service and set the NX Unit to Operational state in advance.
• NX-series Safety Units do not support Change NX state.
• If you execute Change NX Unit state when tag data link communications are established, a
Device state conflict error occurs and the state of the NX Unit does not change. Restart the
EtherNet/IP Unit to enable any changes made with Change NX state.
• You cannot establish tag data link communications during execution of Change NX state.
• To confirm from the user program that I/O data communications for an NX Unit are possible,
use NX Unit Message Enabled Status in the I/O data. To check the Slave Terminal status,
use Slave Terminal Status in the I/O data. For details, refer to Details of I/O Data in the Eth-
erNet/IP Coupler Unit on page 9-15.
