*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.
