System Integration
Redundant PROFINET communication can also be implemented via a socalled media
redundancy protocol (MRP) topology. The HD2-GTR-4PA.PN gateway supports MRP in a ring
according to the PROFINET specification.
For more information, refer to the specific control system documentation of your application.
