4.3 Comparison Output Function 4.3.5 Coincidence detection interrupt function
(3) Interrupt pointer setting method
Assign the interrupt factors (SI) of the QD65PD2 and the interrupt pointers of the CPU module in the intelligent
function module interrupt pointer setting of the programming tool.
Page 250, Section 7.3
When assigning SI0 to 7 of the QD65PD2 to the interrupt pointers I50 to I53 (QD65PD2 is mounted to the
slot whose start I/O number is 20.)
(4) Interrupt timing for each comparison condition
An interrupt occurs at the rising state (off to on) of Coincidence output 1 to 8 (X10 to X17).
Note that interrupt timing depends on the comparison condition.
(a) Coincidence output
The figure below shows the timing of an interrupt signal when the comparison condition for the coincidence
output 1 is coincidence output.
In this case, Coincidence output 1 (X10) must be reset by Reset command (coincidence output 1) (Y10).
