160 Configuration Manual, 03/2015, C79000-G8976-C285-06
Changing the configuration of an existing HRP manager
The configuration of a device in the role as redundancy manager with the HRP redundancy
method cannot be changed to the redundancy method MRP using STEP 7.
The only way to change the redundancy mode is to use manual parameter assignment
methods such as WBM, CLI or SNMP and to activate the "MRP Manager (Auto)/Client" or
"Automatic Redundancy Detection" role.
X-200IRT: No change to the MRP configuration during PROFINET IO operation
With X-200IRT, media redundancy cannot be set during PROFINET IO operation. Set the
X-200IRT to the factory settings to configure MRP using an alternative method (WBM, CLI,
SNMP). After saving the settings on the device using the alternative method, you can create
or modify the MRP configuration in STEP 7.
