Setting procedure
To use the interrupt function, set "Condition target setting", "Condition target channel setting", "Interrupt factor transaction
setting", and "Interrupt pointer" in GX Works3. After completing the settings, write the project to enable the settings.

The following shows the setting items on the interrupt settings window.
Item
Condition target setting
Condition target channel setting
Interrupt factor transaction setting
Interrupt pointer
■Condition target setting
Select a factor of the condition target setting for the interrupt detection.
For details on the factors to be detected, refer to the following.
Page 303 Condition target setting [n]
■Condition target channel setting
Select a target channel when the condition target setting for the interrupt detection is channel specification.
Item
Condition target channel setting
■Interrupt factor transaction setting
Set an interrupt request for when the same interrupt factor occurs during the interrupt factor detection.
• With "Interrupt reissue requests (0)", if the same interrupt factor occurs during the interrupt factor detection, an interrupt
request is sent to the CPU module again.
• With "No interrupt reissue request (1)", if the same interrupt factor occurs during the interrupt factor detection, an interrupt
request is not sent to the CPU module.
■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.
MELSEC iQ-F FX5 User's Manual (Application)
• If 'Condition target setting [n]' (Un\G232 to Un\G247) is Disable (0), no interrupt request is 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.
MELSEC iQ-F FX5 User's Manual (Application)
• 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 Warning output flag (2) etc., the interrupt requests that have the
same interrupt factor are sent to the CPU module if alarms are issued in multiple channels. In this case, the
CPU module executes multiple interrupt programs at a time and thus judges that the program cannot be
normally finished due to the scan monitoring function, and a CPU module error may occur. When a CPU
module error occurs, review the CPU module parameter setting and the program.
Description
Select a factor of the target for the interrupt detection.
Select a target channel when the condition target setting for the interrupt detection is channel specification.
Set an interrupt request for when the same interrupt factor occurs during the interrupt factor detection.
Specify the number of an interrupt pointer that is initiated at the detection of an interrupt factor.
