Interrupt Type and Elements
User Fault Routine (UFR) Interrupt
The UFR interrupt is an interrupt with the highest priority and recovers User
Fau
l
t (Error). The fault routine is executed when any recoverable or
non-recoverable user fault occurs.
The basic types of faults are described below:
• Recoverable Fault
Recoverable Faults are caused by the user and may be recovered from by the
UFR interrupt. To clear the errors, set the SR2.1.13 flag as reset value in the
UFR service routine.
• Non-Recoverable Fault
Non-Recoverable Faults are cover
e
d after Power Cycle (Power On/Off).
External Input Interrupt (EII)
The EII contains 8 of interrupts from EII 0 to 7 according to the priority.
It is supported X1 input port embedded on PLC CPU only.
Followings are descriptions elements related interrupt of SFR.
It is described based on the EII and each eleme
n
ts are used in HSC and PIT
similarly.
