Operation and function
• 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
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.
