Third-Party Mrp Manager Use With Profinet Controller As Mrp Client - GE PACSystems RX3i User Manual

Chapter 6. Redundant Media
6.1.8 Third-party MRP Manager Use with PROFINET Controller as MRP
Client
When using a third-party MRP Manager, it is recommended to set the MRP Manager Test Monitoring
Interval to 10ms and Test Monitoring Count to 2 and/or connect the PROFINET Controller client
directly to a device that provides fast link down detection.
Failure to follow these recommendations may result in degraded MRP Ring update performance for
bumpless operation, due to the speed at which ring breaks are detected.
Use the tables below as a guide when choosing not to follow the recommendations.
