1.13 Interrupt Function
• 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 occur in 'Condition target setting [n]' (Un\G232 to
Un\G247), 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.
