9-2-3 I/O Allocation Information
Registering I/O Entries
The I/O data assigned to an I/O entry mapping is called an I/O entry.
Default values are assigned to the I/O entries in each I/O entry mapping. Some I/O entry mappings
allow you to add or delete I/O entries. Also, the I/O data that you can assign to an I/O entry mapping
is predetermined. Change the I/O entries as necessary.
This section gives the I/O data in the EtherNet/IP Coupler Unit that you can assign as I/O for network
variables.
To access I/O data as NX objects, use the index numbers.
I/O Entry Mappings for EtherNet/IP Coupler Units
The following I/O entry mappings are available.
I/O Data Allocatable to I/O Entry Mappings
The following I/O data can be registered as I/O entries for the I/O entry mappings.
If you use a status that has a number as the suffix to the data name, select a status according to the
number of used NX Units. Doing so will reduce the I/O data size and improve communications per-
