Using Interrupts
* User Fault Routine (URF) configuration part is located in “Error” of SR2
different with other interrupt configuration.
But, the interrupt service routine exe
c
ution can affect to PLC scan time
directly, interrupt processing must be completed in the shortest time. It is
applied to most devices using interrupt.
Priority of User Interrupts
When multiple interrupts occur, the interrupts are serviced based upon their
individual priority.
The priorities from highest to lowest are:
