Remark
(b) How to resume the user program
This section explains how to resume the user program that is waiting for an
interrupt event by the QBF_WaitEvent function.
1) In the user program, call the QBF_WaitEvent function.
2) By 1), the user program is placed into the interrupt event waiting status.
3) In the above 2) status, execute either of the following.
• User program of the other C Controller module (another CPU) (QBF_GINT
function)
• Sequence program of a programmable controller CPU (another CPU)
(S.GINT or D.GINT instruction)
4) The user program is restored from the event waiting status.
