The I/O module supports diagnostic interrupts and hardware interrupts. You can find additional
information on hardware interrupts in the appendix Hardware interrupts (Page 34)
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 32).
The I/O module generates a diagnostics interrupt in case of the following events:
● Wire break
● Supply voltage missing
● Module is faulty
● Channel/component temporarily unavailable
● Hardware interrupt lost
● Parameter assignment error
● Retentive memory in carrier module defective
● Retentive memory in the terminal block defective
