Redundancy Manager and other
Media Redundancy Managers are

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

The PROFINET MRP network ring
is closed/okay.
PNC no longer has a valid MAC
address.
The PNC has encountered a

Cause Recommended Correction
Update the PNC configuration to
change its MRP role to either
Disabled or Client, or remove all
of the other devices on the
network that are also acting as a
Media Redundancy Manager.
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.

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.
