5 I/O Refreshing
5 - 4
NX-series IO-Link Master Unit User’s Manual (W567)
The following shows the operation of I/O refreshing when the built-in EtherCAT port on the NX-series
CPU Unit is used for communications with an EtherCAT Slave Terminal.
• The process data communications cycle in item (b) and the refresh cycle of the NX bus in item (c) are
automatically synchronized with the primary period or the task period of the priority-5 periodic task of
the CPU Unit in item (a).
*1
• The refresh cycle of each NX Unit in item (d) depends on the I/O refreshing method which is given
below.
*1. This applies when the distributed clock is enabled in the EtherCAT Coupler Unit.
The priority-5 periodic task must be supported by the connected CPU Unit model. Refer to the
NJ/NX-series CPU Unit Software User’s Manual
(Cat. No. W501-E1-16 or later) for the periodic
tasks supported by each model of NX-series CPU Unit.
The operation of I/O refreshing is as follows when the built-in EtherCAT port on the NJ-series CPU Unit
or NY-series Industrial PC is used for communications with an EtherCAT Slave Terminal.
• The process data communications cycle in item (b) and the refresh cycle of the NX bus in item (c)
*1
are automatically synchronized with the primary period of the NJ-series CPU Unit or NY-series Indus-
trial PC in item (a).
• The refresh cycle of each NX Unit in item (d) depends on the I/O refreshing method which is given
below.
*1. This applies when the distributed clock is enabled in the EtherCAT Coupler Unit.
Refer to the
NX-series EtherCAT Coupler Unit User's Manual
(Cat. No. W519-E1-08 or later) for
detailed information on I/O refreshing between the built-in EtherCAT port on the NJ/NX-series CPU Unit
and EtherCAT Slave Terminals.
Refer to the user’s manual for the connected Communications Coupler Unit for the I/O response times
of NX Units on Slave Terminals.
