■Restarting user programs
CPU module
Sequence program
1.
Execute the C intelligent function module dedicated function (CITL_WaitYEvent) while executing a user program.
2.
The user program is placed into a state of waiting for an output signal (Y) interrupt event notification.
3.
When the output signal (Y) of a C intelligent function module is turned ON, the user program is restarted.
Precautions
The following shows the considerations when using C intelligent function module dedicated function (CITL_WaitYEvent).
■When an interrupt event has already been notified
When an interrupt event has already been notified at the time of executing the C intelligent function module dedicated function
(CITL_WaitYEvent), a user program restarts from a state of waiting for an interrupt event at the same time as the execution of
the function.
In addition, when multiple interrupt events have been notified to the same interrupt event number at the time of executing the
C intelligent function module dedicated function (CITL_WaitYEvent), a user program performs processing as a single interrupt
event notification.
■When using the function in multiple user programs
Do not specify a same interrupt event (output signal (Y) number) in multiple user programs.
Otherwise, a user program to which a specified interrupt event (output signal (Y) number) is notified will be undefined.
