Redundant Media - Emerson PACSystems RX3i User Manual

RSTI-EP PROFINET I/O Controller User Manual
GFK-2571R
Section 6:
The PACSystems PROFINET Controller supports PROFINET Media Redundancy Protocol
(MRP). The PROFINET Controller can be used as either a Media Redundancy Manager or
Media Redundancy Client on a redundant media ring.
Media Redundancy enables the network to recover from a failure at any single network link
or network node. Because it operates transparently to applications using the network, no
changes to the application are needed to use media redundancy.
This Section describes:
• PROFINET Media Redundancy Protocol
• MRP Performance
• Ring Topology with One Controller
• Ring Topology with Multiple Controllers
• Setting Up Media Redundancy Protocol for a PROFINET IO-Controller
• Sequence for Enabling Media Redundancy
• Sequence for Replacing a Media Redundancy Manager
• Procedure for Disabling Media Redundancy
The following table shows which PROFINET Scanners/Devices support MRP.
