Chapter 6 Applied Instructions 6_ Note: When several interrupts occur simultaneously, the interrupt task whose pointer number is smallest is executed first. The PLC completes the on-going interrupt, and then execute other interrupts according to their pointer numbers. For example, during the execution of I400 interrupt, if I500 and I300 occur simultaneously, the PLC executes the I300 interrupt (smaller pointer number) after executing the I400 interrupt. 6-167 Interrupt Maskable interrupts Description Bit No. number SR instruction completes I504 High-speed output interrupt: the 5th axis positioning instruction completes 4 I505 High-speed output interrupt:
the 6th axis positioning instruction completes 5 I510 High-speed output interrupt 1: the position planning table instruction completes SR630 0 I511 High-speed output interrupt 2: the position planning table instruction completes 1 I512 High-speed output interrupt 3: the position planning table instruction completes 2 I513 High-speed output interrupt 4: the position planning table instruction completes 3 I514 High-speed output interrupt 5: the position planning table instruction completes 4 I515 High-speed output interrupt 6: the position planning table instruction completes 5 I516 High-speed output interrupt 7:
