NX-series EtherNet/IP Coupler Unit User’s Manual (W536)
13-2 Maintenance Procedures
This section describes the procedures to replace the Slave Terminal components.
The EtherNet/IP Coupler Unit stores NX Unit setting data. If you replace the EtherNet/IP Coupler Unit,
you must restore the settings for the EtherNet/IP Coupler and the NX Units using the Support Software.
Replacing an NX Unit on a previously configured EtherNet/IP Coupler Unit will cause that NX Unit to
inherit settings from the EtherNet/IP Coupler Unit.
You can use the Support Software to export and import the Slave Terminal settings and NX Unit set-
tings as files. This allows you to reuse settings from an Slave Terminal or NX Units for other Slave Ter-
minals or NX Units such as:
• Unit configuration information
• I/O allocation information
• Unit operation settings
• Hardware switch information
Refer to 9-2-6 Support Software Functions Used as Required on page 9-24 for more information about
importing and exporting Slave Terminal settings.
