I/O Refreshing Method Setting

There are the following methods to exchange data between SSI Input Units and the Controller: 
Free-Run refreshing, synchronous I/O refreshing, and task period prioritized refreshing.

This section describes how to set the I/O refreshing method for SSI Units, the I/O refreshing methods, 
and the differences in I/O refreshing methods for different Controllers.

This section describes the settings of the I/O refreshing method for each Communications Coupler Unit.

EtherCAT Coupler Unit

When an SSI Input Unit is connected to an EtherCAT Coupler Unit, the I/O refreshing method 
depends on the 

Enable Distributed Clock 

setting.

The following table lists the possible combinations.

Version Information

Unit version 1.2 or later and an NX-ECC203 EtherCAT Coupler Unit are required to use task 
period prioritized refreshing. If you use unit version 1.1 or earlier and an NX-ECC203 EtherCAT 
Coupler Unit, operation is performed with synchronous I/O refreshing.

EtherNet/IP Coupler Unit

When an SSI Input Unit is connected to an EtherNet/IP Coupler Unit, you can use only Free-Run 
refreshing. There is no setting.

The following table lists the refresh cycles for Free-Run refreshing, synchronous I/O refreshing, and 
task period prioritized refreshing.
