Interrupt Function - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

Interrupt function

Executes an interrupt program of the CPU module when an interrupt factor such as an input signal error or alarm output is
detected.
The number of available interrupt pointers per analog input module is up to 16.
Operation
■Detecting an interrupt factor
When an interrupt factor occurs, an interrupt request is sent to the CPU module at the same time as 'Interrupt factor detection
flag [n]' (Un\G4 to Un\G19) turns to Interrupt factor (1).
■How to reset an interrupt factor
When Reset request (1) is set to 'Interrupt factor reset request [n]' (Un\G156 to Un\G171) corresponding to the interrupt factor,
the specified interrupt factor is reset and 'Interrupt factor detection flag [n]' (Un\G4 to Un\G19) changes to No interrupt factor
(0).
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.

■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 137 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.
