7.5.1 Flexi Link ID mismatch
Error description
If no process image transfer is possible between the stations in your system and all
CPU modules show a recoverable error (MS LED flashing
Red at 1 Hz and EFI1
and EFI2 LEDs light up Red), this could be due to a Flexi Link ID mismatch. This
means that at least one of the stations in the system has one or two Flexi Link IDs that
differ from the other stations’ Flexi Link IDs.
Diagnostics
Switch to the Flexi Link System overview.
If the Setting and Monitoring Tool is not connected to the system, connect to all
stations.
Check the status messages of the stations for indication of a Flexi Link ID mismatch.
Correction of the error
If different Flexi Link IDs exist in the system, the current configuration must be
transferred to all stations again.
Check whether the configuration in the Setting and Monitoring Tool is correct.
Connect to all stations.
Transfer the configuration to all stations.
Switch to the view for each station and verify the configuration if necessary.
