A-3-5 Initializing the Unit Operation Settings of One NX Unit
This procedure initializes the Unit operation settings of one NX Unit in the EtherNet/IP Slave Terminal.
The unit number of the relevant NX Unit is 1.
The setting procedure is given in the following table.
You can read and write the I/O data of an EtherNet/IP Slave Terminal using explicit messages from a
device that does not support tag data link (implicit message) communications.
When you use an EtherNet/IP master that does not support explicit messages, you can use the
TCP/UDP message service to read and write the I/O data of an EtherNet/IP Slave Terminal.
The procedure is given in the following table.
