10 I/O Refreshing
10 - 6
NX-series EtherCAT Coupler Unit User’s Manual (W519)
10-3 I/O Refreshing for EtherCAT Slave Ter-
minals
This section describes I/O refreshing between the built-in EtherCAT port on the NJ-series CPU Unit and
EtherCAT Slave Terminals.
The EtherCAT Coupler Unit is an EtherCAT slave that supports DC synchronization.
The I/O refreshing between the built-in EtherCAT port on the NJ-series CPU Unit and the EtherCAT
Coupler Unit is the same as the operation of DC Mode that is described in
There is more than one I/O refreshing method that you can use between the EtherCAT Coupler Unit
and the NX Units. The I/O refreshing methods that you can use between the EtherCAT Coupler Unit
and the NX Units are listed below.
Because the EtherCAT Coupler Unit can perform all I/O refreshing methods at the same time, NX Units
with different I/O refreshing methods can be used together in the EtherCAT Slave Terminals.
Refer to the manuals for the specific NX Units for details on the operation for each I/O refreshing
method.
The I/O refreshing method between the EtherCAT Coupler Unit and each NX Unit depends on whether
the DC is enabled in the EtherCAT Coupler Unit.

Coupler Unit
I/O Refreshing between the EtherCAT Coupler Unit and NX Units
I/O refreshing method name
Outline of operation
Free-Run refreshing
With this I/O refreshing method, the refresh cycle of the NX bus and the I/O
refresh cycles of the NX Units are asynchronous.
Synchronous I/O refreshing
With this I/O refresh method, the timing to read inputs or to refresh outputs is syn-
chronized on a fixed interval between more than one NX Unit on more than one
Slave Terminal.
10-3-2 Setting the I/O Refreshing Methods
DC enable setting in the Ether-
CAT Coupler Unit

NX Units that support both
Free-Run refreshing and syn-
chronous I/O refreshing
Enabled (DC Mode)
