1.2 Restrictions on Units Combination1-5(Note): When a mark "*" is displayed in the INT column, it indicates that the mode setting switch on the side of the unitis set to "use the interrupt function".1.2.3 Restrictions on Interrupt FunctionThe multi input/output unit can start an interrupt program of the CPU unit using an interruptinput or counter comparison match flag. The interrupt function can be used within thefollowing range. Interrupt program specificationsItem SpecificationsNo. ofinterruptprogramsPer multi input/outputunit Max. 8 programsPer CPU unit Max. 64 programs (8 programs x 8 units)(Note 1) If interrupts occur many times in one scan, the execution of interrupt program has priority, and the scan timewill be longer.(Note 2) If more than one interrupt activation request is made from the unit, the process will be carried out from thesmallest slot number or the smallest interrupt program number.
