9.1.4 Precautions for Use

 Process when more than one interrupt activation request is made
• If more than one interrupt activation request is made from the unit, the process will be
carried out from the smallest slot number or the smallest interrupt program number.
• If the interrupt activation is requested on the completion of the process of interrupt program,
a higher-priority program will be searched and the corresponding interrupt program will be
executed.
• Interrupt activation request signals on the unit side will be held until the corresponding
interrupt program is executed or ICLR instruction is executed.
•
If interrupt occurs many times in one scan, the execution of interrupt
program has priority, and the scan time will be longer.
