Flexi Link
The Flexi Link IDs are also displayed in the Flexi Link Network settings view.
If the configuration of any station in the Flexi Link system is changed in a way that
affects the process image of the system (e.g. if a station is added to the system or if
the default value for one of the transmitted bits is changed), then the Setting and
Monitoring Tool calculates a new Flexi Link ID based on the changed process image.
In this case you have to transmit the configuration to all stations in the system, not
only to the station whose configuration you have changed. Otherwise the new Flexi
Link IDs will be transferred only to this station while the other stations will keep the old
Flexi Link IDs. The resulting Flexi Link ID mismatch between the stations will disrupt
the process image communication in the system. If a differing Flexi Link ID is detected,
no process image transfer between the stations is possible and all CPU modules
(WS0-CPU1) in the system will show a recoverable error (MS LED flashing
1 Hz and EFI1 and EFI2 LEDs will light up Red). Only configuration and diagnostics of
the stations is still possible then.
For more information on how to correct a Flexi Link ID mismatch please see Section 7.5.
