 I/O Refreshing with a Master from Another Manufacturer That Supports DC
Synchronization
In this case, EtherCAT Slave Terminals can operate only in DC Mode.
NX Units that support synchronous I/O refreshing and Free-Run refreshing can operate in the DC
Mode with synchronous I/O refreshing. However, not all of the NX Units that use synchronous I/O
refreshing in all Slave Terminals that are not connected to the same EtherCAT network will read
inputs and refresh outputs simultaneously.
To operate an EtherCAT Slave Terminal in DC Mode, set up communications in the software from
another manufacturer so that the EtherCAT Slave Terminal operates in DC Mode. NX Units that sup-
port synchronous I/O refreshing and Free-Run refreshing are automatically set to use synchronous
I/O refreshing when you set up communications on the software from another manufacturer so that
the EtherCAT Slave Terminal operates in DC Mode.
