SETTING MRP ROLES

SETTING MRP ROLES
Within an MRP ring, each device must be assigned a role. One device will be the MRP
Manager (MRM) and will be responsible for sending out test frames to detect for a net -
work failure and for blocking network traffic on one port (except for the test frames) to
prevent a network loop. The other devices must be assigned a Client role (MRC) so they
know how to handle the test frames.
So let's set our PLC as the manager.
Go to the Device view for the PLC and look at the properties of the network interface.
Under Advanced Options, look for Media redundancy. Here you can select the role for
the device: set the Manager (Auto) option in the Media redundancy role drop-down
menu.

We do the same for the encoder: it must be set as a client.
Go to the Device view for the encoder and look at the properties of the network inter
-
face. Under Advanced Options, look for Media redundancy. Here you can select the role
for the encoder: set the Client option in the Media redundancy role drop-down menu.
