PACSystems* RX3i PROFINET Controller Manual – December 2011

Cause
The PNC is configured as a
Media Redundancy Manager
and it had detected that multiple
Media Redundancy Managers
were on the network, but now
those other managers are no
longer present.
The PROFINET MRP network
ring is broken.
The PROFINET MRP network
ring is closed/okay.
PNC no longer has a valid MAC
address.
The PNC has encountered a
problem attempting to configure
media redundancy operation.
PNC has encountered an
internal error during its
operation.
The temperature detected by the
PNC has exceeded its safe
operating temperature.
PNC application code restarted
due to a hardware watchdog
timeout.
The PNC has become heavily
loaded with activity (Continued
use in this mode may cause
degradation of system
performance (possibly including
delayed IO updates) and
potential loss of network
communications.
Load applied to PNC has been
reduced to an acceptable level,
after it was previously heavily
loaded.
Recommended
Correction
No action necessary. The network is
expected to only have a single Media
Redundancy Manager present.
The MRP Ethernet ring is broken.
Possible causes include damaged or
disconnected cable or power loss to a
node or switch. Locate and repair the
cause(s).
No action necessary. This is the normal,
expected state of an MRP Ethernet ring.

Reduce the temperature of the
environment where the PNC is operating.
Contact customer service.
Reduce load on PNC. One or more of
the following can be tried to reduce load:

Increase the configured update rate
value (i.e. IO received less
frequently) of one or more
PROFINET Devices configured on
the PNC.

Reduce the number of PROFINET
Devices configured on the PNC.
None.
