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

• Operation when 'Disconnection detection automatic clear enable/disable setting' (Un\G304) is Enable
Disconnection detection flag (Un\G38, b0)
Disconnection detection signal (Un\G69, b13)
Error clear request (Un\G70, b15)
At the same time analog output restarts, the disconnection detection flag (Un\G38) of the corresponding channel is cleared. In
addition, when the analog output of all channels restarts, 'Disconnection detection signal' (Un\G69, b13) is cleared.

Interrupt function

Executes a CPU module interrupt program when an interrupt factor such as a disconnection or warning output is detected.
The number of available interrupt pointers per analog output 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 in '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).
