4.2.4 PROFINET Module Loss, Add and Mismatch Faults
The PAC8000 PROFINET Scanner uses standard PROFINET Pull/Plug alarms to indicate
differences between the configured modules and the actual modules present in the PNS.
■
If a module is configured, but is not present or not operating correctly, the PNS
indicates the module as removed via a Pull Alarm.
■
If a different IO module is hot-inserted than configured while an Application
Relationship is active, the PAC8000 PROFINET Scanner reports the mismatch using
a Plug Wrong Submodule alarm.
■
PNS does not generate alarms for an un-configured slots. The module is ignored by
the PNS and remains at its module defaults.
■
When a configured IO module is plugged into a configured slot, PNS sends a Plug
Alarm.
■
Configuration related alarms are generated when user configuration is not valid. For
each invalid configuration of a IO module, an alarm is generated. If all modules have
invalid configuration, 32 alarms will be generated. Note that only one alarm per IO
module is generated (even though more than one invalid configuration exists on a
module). If an IO module has an invalid configuration, an alarm is generated and that
IO module will not be put under IO scan.
