■Interrupt pointer
Specify the number of an interrupt pointer that is initiated at the detection of an interrupt factor. For details on the interrupt
pointers, refer to the following.

Precautions
• If 'Condition target setting [n]' (Un\G232 to Un\G247) is Disable (0), an interrupt request is not sent to the CPU module.
• 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 also share the same setting of 'Condition target setting [n]' (Un\G232 to Un\G247). When
interrupts with the same settings in 'Condition target setting [n]' (Un\G232 to Un\G247) occur, the interrupt program is
executed in order of the 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 each channel of 'Condition target setting [n]' (Un\G232 to Un\G247), the interrupt requests that have the
same interrupt factor are sent to the CPU module if alerts are issued in multiple channels. In this case, the CPU module
executes multiple interrupt programs and judges that the program cannot be normally finished due to the scan monitoring
function, and a CPU module error may occur. When a CPU error occurs, refer to the following.
