A redundant system requires two MLinks connected to the same switchgear bus. In this configuration the MLinks are synchronized using a redundant link cable.

For more information concerning redundant operation please refer to the MNS iS Interface Manual Redundancy.

MLink is not able to create internal database. Please reboot the MLink. If that doesn’t resolve the problem use MNavigate to download the MLink configuration again.

During startup MLink is checking if all required xml files are available. In case of a missing file that error is indicated. Please use MNavigate to download the MLink configuration again.

MLink is not able to configure the IP settings as mentioned in configuration file e.g. due to wrong setting of Default Gateway parameter for that Ethernet Interface. Please use MNavigate to check the settings and download the MLink configuration again. If a download is not possible please use a flash card reader (ref. to MNavigate Help or MNavigate Manual).

Please check if MLink hardware (the identity number) matches to the project specification (e.g. Profibus MLink <-> Profibus project). Furthermore the DataMapping should be checked. Please use MNavigate to download the MLink configuration or download Mapping file again (ref. to MNavigate Help or MNavigate Manual).

Please use MNavigate to check the redundancy status (Redundancy Report) . If a mismatch was found please download the regarding file. For details please refer to MNavigate Help or MNavigate Manual.

Check if the correct IP address in the address bar of the web browser has been entered.

Check if the MLink is powered on and no fault indication is on the LED indication of MLink.

Check if the Web Server option is activated. This option is customer project specific and can only be enabled using MNS Engineering Tools. If available it can be used to check communication to the MLink.

If the MLink is still not reachable; Remove the CF card from MLink, insert the CF card into a card reader connected to MNavigate and write the MLink data again to the CF card. Ensure that correct address settings are entered for MLink. Re-insert the card to MLink and start MLink and check communication.
