Precautions
• When 'Condition target setting [n]' (Un\G232 to Un\G247) is Disable (0), an interrupt request is not sent to the CPU module.
• If an interrupt factor occurs when 'Interrupt factor mask [n]' (Un\G124 to Un\G139) is Mask (Interrupt unused) (0), an
interrupt request is not sent to the CPU module. 'Interrupt factor detection flag [n]' (Un\G4 to Un\G19) is turned 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) are 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, a CPU error may
occur because the CPU module executes multiple interrupt programs and the scan monitoring function of the CPU module
judges that the programs cannot be normally completed. When a CPU error occurs, refer to the following.
