MRP Ring Redundancy
The ring topology is achieved by extending a line topology back to its starting
point. A network redundancy ring protocol such as PROFINET MRP (see
Appendix A MRP Ring Redundancy) must be supported by all devices that
form the ring. This allows monitoring the state of the network and reconfiguring
the communication paths in case of a disturbance..
Advantage of a ring topology:
•
Disadvantage of a ring topology:

/i
This protocol, which is part of the PROFINET IO Specification, enables the
Unit to be part of a ring-shaped network structure and adds redundancy to the
network. The internal Ethernet Switch of for instance the Omron GRT1-PNT IO
Device Unit supports the Media Redundancy Protocol (MRP).
In case one of the line connections fails, the MRP ensures communication to
all IO Devices through the redundant path. The ring structure can contain up to
50 Units and typically switches to the redundant path within 150ms (max
500ms).
Part
Switch
Malfunction of a single IO Device will not result in disconnection of part of
the network as the network redundancy mechanism will automatically
maintain the connection with the other devices.
Malfunction or power disruption to the MRP manager will result in
disconnection of the entire network.
High data traffic per connection.
Recommendation
Industrial Ethernet Switch supporting MRP manager function.
Suggestion: Hirschmann Automation and Control GmbH,
Series RS20/30/40, Software Version 4 or higher.
