5.2 Interrupts

5.2 Interrupts
The I/O module supports diagnostics interrupts and hardware interrupts. You can find
additional information about hardware interrupts in appendix "Hardware interrupts (Page 56)".
Diagnostics interrupts
Diagnostics interrupts are used by the I/O module to signal diagnostics messages as well as
maintenance events, see also appendix Diagnostics messages and maintenance events
(Page 51).
The I/O module generates a diagnostics interrupt at the following events:
● Overtemperature
● Channel/component temporarily unavailable
● Short-circuit / overload of sensor supply
● Wire break
● Low limit violated (underflow)
● High limit violated (overflow)
● Supply voltage missing
● Hardware interrupt lost
● Module is faulty
● Short-circuit of an analog input to sensor supply or L+
● Retentive memory in carrier module defective
● Retentive memory in the terminal block defective
● Redundancy partner has different hardware/firmware
● IO redundancy warning
● Redundancy parameter assignment inconsistent
● HART communication error
● HART field device error
Note
The diagnostics "Module is defective" and "Excess temperature" are not cleared again by the
module without a restart.
