Cyclic I/O Refreshing The EtherNet/IP Coupler Unit exchanges I/O data with
the mounted NX Units.

Refreshing
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.

connected to the actual configuration but will be added at
a later time in the Unit configuration information as
