5-2 I/O Refreshing Methods

5-2-9 Output Refreshing with Specified Time Stamp
With this I/O refreshing method, the Output Units refresh outputs at the DC times specified by the user
program. The specified DC times are not synchronized to the NX bus refresh cycles. Among Slave
Terminals, only EtherCAT Slave Terminals support this refreshing method.
The CPU Unit or EtherCAT Coupler Unit cyclically sets the output set values and the DC times to
refresh outputs to the Output Units on the NX bus refresh cycles.
In the descriptions below, the DC time to refresh the output is called the specified time.
You can use the Input Units that support input refreshing with input changed time with the Output Units
that support output refreshing with specified time stamp to control outputs at fixed intervals after the
sensor inputs change.
