FPN replaces the existing MMS configuration. The relay's booting time is longer due to processing of project-specific configuration. The configuration size is compared to the maximum recommended configuration size and a warning is given if the configuration size exceeds the recommended maximum.
The tool does not download the configuration if the relay's capabilities are exceeded. The configuration size warning is given when the project is larger than verified in ABB. In this case, it is recommended to check and minimize unnecessary options.
The configuration size can be minimized in several ways.
- Decrease the number of RCB clients per control block. This can be checked from //ReportControl/RptEnabled/@max.
- Decrease the number of report controls and data sets
- Remove the unnecessary logical nodes from configuration. The data model size can be minimized if a replaced relay is configured with a default configuration or a configuration which contains unused functions.
