Designing the Tasks Reference
 Design the task configuration.
Design the task configuration based on the I/O response perfor-
mance that is required by the controlled devices.

ods and I/O Response
Times
 Determine whether to use the primary periodic task or the
priority-16 periodic task for the I/O refreshing of each Unit
and slave.
5-2-10 Assigning I/O
Refreshing to Tasks
 Determine which programs to assign to the primary
periodic task, to the priority-16, priority-17, and priority-18
periodic tasks, and to the priority-8 and priority-48 event
tasks.
5-2-11 Assigning
Tasks to Programs
 Design the exclusive control methods for variables
between tasks.
Design the exclusive control methods for variables between tasks
when the same global variables are used in different tasks.
5-2-13 Ensuring Con-
currency of Variable
Values between Tasks
 Design the tasks to access variables from outside of the
Controller.
Design the tasks to enable synchronization of accessing variables in
the CPU Unit from outside of the Controller with the execution of a
program in a specific task. EtherNet/IP tag data links are included in
accessing variables.
