This section describes I/O refreshing.
I/O Refreshing with a Master from Another Manufacturer That Does Not Sup-
port DC Synchronization
In this case, EtherCAT Slave Terminals can operate only in Free-Run Mode.
NX Units that support Synchronous I/O refreshing and Free-Run refreshing can operate in the
Free-Run Mode with Free-Run refreshing.
To operate an EtherCAT Slave Terminal in Free-Run Mode, set up communications in the software
from the other manufacturer so that the EtherCAT Slave Terminal operates in Free-Run Mode. NX
Units that support synchronous I/O refreshing and Free-Run refreshing are automatically set to use
Free-Run refreshing when you set up communications on the software from another manufacturer
so that the EtherCAT Slave Terminal operates in Free-Run Mode.
