3-3-2 I/O Port Names
The I/O port names are registered automatically. The I/O port names differ as given below depending
on whether the device (i.e., Unit or slave) is an EtherCAT slave, CJ-series Basic I/O Unit, or CJ-series
Special Unit.
The following I/O port names are used for Remote I/O Terminals that are EtherCAT slave devices.
Example for a 16-point Remote I/O Terminal: Bit00 to Bit15
For other slaves, all or part of the object names that are defined in the EtherCAT object dictionary are
used.
Example for Analog Input Unit: CH0_input16-bit
Examples for the R88D-KN50H-ECT: Position actual value and Digital inputs
If the device is a CJ-series Basic I/O Unit, I/O port names are created according to the following rules.
