Interrupts

The I/O module supports diagnostic interrupts and hardware interrupts. You can find additional
information on hardware interrupts in the appendix Hardware interrupts (Page 70)
Diagnostics interrupts
Diagnostics interrupts are used by the I/O module to output both diagnostic messages and
maintenance events; see also the appendix Diagnostics messages and maintenance events
(Page 66).
The I/O module generates a diagnostic interrupt for the following events:
● Overtemperature
● Wire break at a digital output
● Wire break at an analog input
● High limit violated (overflow)
● Low limit violated (underflow)
● Parameter assignment error
● Supply voltage missing
● Hardware interrupt lost
● Channel/component temporarily unavailable
● Module is faulty
● Short-circuit of an analog input to sensor supply or L+
● Digital output short circuit to M
● Sensor supply short circuit / overload
● Button switch-off
● Retentive memory in carrier module defective
● Retentive memory in the terminal block defective
● Redundancy partner has different hardware/firmware
● IO redundancy warning
● IO redundancy parameter assignment inconsistent
● HART communication error
● HART field device error
Note
A pending "Module is defective" or "Excess temperature" or "Button switch-off" diagnostic is
not deleted by the module without a restart.
