s
In the NJ/NX-series Controller, the I/O refreshing processing, user program processing, and MC Func-
tion Module processing between the Position Interface Units are executed in the primary periodic task
and priority-5 periodic task.
Refer to
NJ/NX-series CPU Unit Software User's Manual
(Cat. No. W501) for information on the pri-
mary periodic task and priority-5 periodic task.
The following figure shows an example of the task operation performed for I/O processing for the Posi-
tion Interface Units in the primary periodic task. The same information applies when processing is per-
formed in the priority-5 periodic task.
The input information is obtained from the Position Interface Units every fixed period that the task is
executed. Processing (user program execution and motion control processing) is then performed based
on that information, and the information is sent as an output command.
