■Interrupt factor transaction setting
Set whether to send an interrupt request when the same interrupt factor occurs during the interrupt factor detection.
• When "Interrupt reissue request" has been set and the same interrupt factor occurs while the interrupt factor has been
detected, an interrupt request is sent to the CPU module again.
• When "No interrupt reissue request" has been set and the same interrupt factor occurs while the interrupt factor has been
detected, an interrupt request is not sent to the CPU module.
■Interrupt pointer
Specify the number of an interrupt pointer that is started at the detection of an interrupt factor. For details on the interrupt
pointers, refer to the following.

Precautions
• When 'Condition target setting [n]' (Un\G232 to Un\G247) is Disable (0), an interrupt request is not sent to the CPU module.
• When 'Interrupt factor mask [n]' (Un\G124 to Un\G139) is Mask (Interrupt unused) (0) and an interrupt factor occurs, an
interrupt request is not sent to the CPU module. However, 'Interrupt factor detection flag [n]' (Un\G4 to Un\G19) changes to
Interrupt factor (1).
• To reset the interrupt factor, set Reset request (1) until 'Interrupt factor detection flag [n]' (Un\G4 to Un\G19) changes to No
interrupt factor (0).
• Resetting interrupt factors is executed only when 'Interrupt factor reset request [n]' (Un\G156 to Un\G171) changes from No
reset request (0) to Reset request (1).
• Multiple interrupt pointers can share the same setting of 'Condition target setting [n]' (Un\G232 to Un\G247). When multiple
interrupt pointers have shared the same setting of 'Condition target setting [n]' (Un\G232 to Un\G247) and interrupts occur,
interrupt programs are executed in order of priority of the interrupt pointers. For the priority of the interrupt pointers, refer to
the following.

• When All channels (0) is set for 'Condition target channel setting [n]' (Un\G264 to Un\G279) and an interrupt detection
target is set for 'Condition target setting [n]' (Un\G232 to Un\G247) of each channel, the interrupt requests that have the
same interrupt factor are sent to the CPU module if warnings are issued in multiple channels. In this case, the CPU module
executes multiple interrupt programs and judges that the programs cannot be normally completed with the scan monitoring
function, and a CPU error may occur. When a CPU error occurs, refer to the following.
