13-3 I/O Response Time in Tag Data Links
Additional Information
This section describes the response time of the NY-series Controller built-in Ethernet/IP port.
The data processing times for the EtherNet/IP Unit, the built-in EtherNet/IP port on the NX- and
NJ-series Controller, the built-in EtherNet/IP port on the CJ2H-CPU6
-EIP CPU Unit and the
built-in EtherNet/IP port on the CJ2M-CPU3
CPU Unit are different. For details, refer to
Tag Data Links with Other Models
.
The following diagram shows the timing of tag data link transfers between the built-in EtherNet/IP port
and the Controller. Data is transferred when system common processing 2 is performed for the task set
as the refreshing task.
You can set either of the following types of tasks as the refreshing task.
•
Primary periodic task
The primary periodic task has the highest execution priority. It executes processes with high speed
and high precision.
•
Periodic tasks
Periodic tasks are executed during the time between executions of the primary periodic task.
The task during which to perform tag data link processing is specified for each tag. Set the refreshing
task on the Sysmac Studio for each variable you want to set as a tag. Refer to the
Sysmac Studio Ver-
sion 1 Operation Manual
(Cat. No. W504) for details on setting refreshing tasks.
