Fault Contacts
If the RX3i application needs to monitor the real-time status of PROFINET inputs and/or outputs, it
must refer to the I/O point fault contacts associated with the remote I/O module. Point fault contacts
are set if the device is missing or the IO Producer or Consumer Status (IOxS) indicate a
bad
data
status for the corresponding IO.
Fault Locating References
The Fault-Locating References for a PNC module can be used for rack-level and slot-level faults.
These names can be programmed on the FAULT and NOFLT contacts:
#RACK_000r
#SLOT_0rss
where
r
represents the rack number and
ss
represents the slot number
These names
cannot be
used to check for faults on a PROFINET IO-Device, remote module, or
remote sub-module.
The reserved fault names are always available. These fault names do not correspond to %SA, %SB,
%SC, or to any other reference type. They are mapped to a memory area that is not
user-accessible.
Fatal Error Reporting
If the PNC encounters a Fatal error, it tries to save diagnostic information to non-volatile storage.
The RX3i CPU then resets the PNC.
Diagnostic information can be viewed from the Command Line Interface using the
show debug
fataIInfo
command.
