• When 'Condition target setting [n]' (Un\G232 to Un\G247) has been set to Disable (0), no interrupt request is
sent to the CPU module.
• To reset an interrupt factor, set 'Interrupt factor reset request [n]' (Un\G156 to Un\G171) to Reset request (1)
until 'Interrupt factor detection flag [n]' (Un\G5 to Un\G20) changes to No interrupt factor (0).
• Interrupt factors are reset only when 'Interrupt factor reset request [n]' (Un\G156 to Un\G171) changes from
No reset request (0) to Reset request (1).
• The same setting of 'Condition target setting [n]' (Un\G232 to Un\G247) can be set to multiple interrupt
pointers. When an interrupt of 'Condition target setting [n]' (Un\G232 to Un\G247) that has been set to
multiple interrupt pointers occurs, interrupt programs are executed following the priority of the interrupt
pointers. For the priority of interrupt pointers, refer to the following:

• When 'Condition target channel setting [n]' (Un\G264 to Un\G279) has been set to All channels (0), an
interrupt detection target has been set to each channel of 'Condition target setting [n]' (Un\G232 to
Un\G247), and alerts occur in multiple channels, interrupt requests that have the same factor will be sent to
the CPU module for several times. At this time, the CPU module executes multiple interrupt programs
simultaneously, the scan monitoring function of the CPU module judges the programs cannot be completed
successfully, and a CPU error may occur. When a CPU error occurs, refer to the following:
