Interrupt Disable (Refer to Subsection 35.2.1.) for details.
M8050 (input interrupt)
I00
disable
*4
•
If an input interrupt or timer interrupt occurs while
a special auxiliary relay for that interrupt (M8050 -
M8058) is ON, the interrupt will not operate.
For example, turning M8050 ON disables the
I00
interrupt; hence, the interrupt routine is not
processed even in an allowable program area.
•
If an input interrupt or timer interrupt occurs while
a special auxiliary relay for that interrupt (M8050 -
M8058) is OFF,
a) The interrupt will be accepted.
b) The interrupt routine will be processed
promptly if it is permitted by the EI (FNC 04)
instruction. However, if the DI (FNC 05)
instruction disables interrupts, the interrupt
program will not be processed until EI (FNC
04) permits the interrupts.
