I/O refreshing is performed between the EtherCAT master and EtherCAT slaves and between the
EtherCAT Coupler Unit and the NX Units. The ranges of refreshing are given in the following table.
The operation of refreshing between the built-in EtherCAT port on the NJ-series CPU Unit and the NX
Units on the EtherCAT Slave Terminal is determined by the combination of the I/O refresh types for the
above ranges.
The rest of this section gives a general description of I/O refreshing between the built-in EtherCAT port
on the NJ-series CPU Unit and EtherCAT slaves. This is followed by a description of I/O refreshing with
the NX Units on EtherCAT Slave Terminals.
