Precautions For Use - Panasonic FP7 User Manual

 Corresponding interrupt program numbers
Interrupt
program no.
INTPG 10 INT0 (Input X8 or EQ0)
INTPG 11 INT1 (Input X9 or EQ1)
INTPG 12 INT2 (Input XA or EQ2)
INTPG 13 INT3 (Input XB or EQ3)
INTPG 14 INT4 (Input XC or EQ4)
INTPG 15 INT5 (Input XD or EQ5)
INTPG 16 INT6 (Input XE or EQ6)
INTPG 17 INT7 (Input XF or EQ7)
(Note 1): Interrupt program numbers are specified with slot numbers + (0 to 7).The numbers in the above table are for
the slot 1.
Example) The program number corresponding to the interrupt INT3 of the multi I/O unit of the slot number 10 is
INTPG03.
KEY POINTS
• Either interrupt (X8-XF) by an external input or comparison match signal
(EQ0-EQ7) when using the comparison output function is allocated to the
interrupt number of the multi I/O unit by the tool software or the setting with
a program. For details of the comparison match signals (EQ0-EQ7), refer to
"8.1.2 Comparison Output and Comparison Match Signal".

6.1.5 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 interrupts occur many times in one scan, the execution of interrupt
•
program has priority, and the scan time will be longer.
