Diagnostics interrupts
Diagnostic interrupts are used by the IM 155-6 PN HA to signal diagnostic messages as well
as maintenance events, see also appendix Diagnostics messages and maintenance events
(Page 31)
The IM 155-6 PN HA generates a diagnostic interrupt for the following events:
● Faulty 24 V DC power supply
● Module parameter errors or incorrect carrier present in real slot
● Failure of redundancy partner
● Redundancy partners have different hardware/firmware
● Impermissible bus adapter on interface module
● Incorrect bus adapter in redundancy partner
● Defective retentive memory in bus adapter
● Permissible backplane bus size exceeded
● No server module
Diagnostics of I/O modules are forwarded by the IM 155-6 PN HA and depend on the respective
I/O module.
Maintenance messages
The IM 155-6 PN HA generates a maintenance message for the following events:
● Different hardware/firmware in the redundancy partners
● IO redundancy warning
● Redundancy parameter assignment inconsistent
● Retentive memory in carrier module defective
● Defective retentive memory in bus adapter
