5.2 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 57)
Diagnostics interrupts
Diagnostics interrupts are used by the I/O module to signal diagnostic messages as well as
maintenance events, see also appendix Diagnostics messages and maintenance events
(Page 54)
The I/O module generates a diagnostic interrupt at the following events:
● Wire break
● High limit violated
● Low limit violated
● Parameter assignment error
● Supply voltage missing
● Reference channel error
● Hardware interrupt lost
● Channel/component temporarily unavailable
● Module is faulty
● Redundancy partners have different hardware / firmware
● IO redundancy warning
● Redundancy parameter assignment faulty
● Retentive memory in carrier module defective
● Retentive memory in terminal block defective
Note
A pending diagnosis "Module is defective" is not deleted by the module until a restart.
