■If an interrupt cause with the same or a lower priority occurs while the interrupt program is
being executed
• For I0 to I23 and I50 to I177
The occurred interrupt cause is memorized, and the interrupt program corresponding to the factor will be executed after the
running interrupt program finishes. Even if the same interrupt factor occurs multiple times, it will be memorized only once.
Higher
Priority
rank
I100 interrupt program
Lower
• For I28 to I31
The interrupt cause that occured is memorized, and the interrupt program corresponding to the cause will be executed after
the running interrupt program finishes. If the same interrupt cause occurs multiple times, it will be memorized once but
operation at the second and later occurrences depends on setting of the fixed scan execution mode. (Page 26 Fixed scan
execution mode)
When "Execution Count Takes Priority" is enabled, the interrupt program corresponding to the memorized interrupt causes will
be executed after the running interrupt program finishes. When "Precede Fixed Scan" is enabled, the second and later
occurrences will not be memorized.
