Firmware upgrade considerations

Ensure that the firmware version you are upgrading to is compatible with your meter, and that the version number is greater than your existing firmware (or else you will downgrade your meter).

Your meter’s existing template may not work with different firmware versions if significant meter features have been added or modified.

Your firmware upgrade files have digital signature confirmation to help ensure your firmware’s authenticity. Once you have upgraded your firmware to a version that uses digital signature confirmation, you cannot downgrade to an earlier firmware version that did not use digital signature authentication.

Remote display (RMD) upgrade behavior

Your meter’s remote display will upgrade as soon as the upgrade file is put in the remote display upgrade folder on your meter’s internal SFTP site. It is deleted as part of the upgrade process.

NOTE: If your meter’s remote display loses power during firmware upload, the display will revert to its original firmware and you will have to reload the firmware file.

The results of your remote display firmware upgrade are stored in your meter’s event log. Detailed information about your remote display, such as serial number and firmware version is provided in the Factory module.

See the ION Reference, available from www.schneider-electric.com, for more information about the Factory module.

Option module(s) upgrade behavior

To upgrade option modules, you must load the upgrade file into the appropriate folder on the meter’s internal SFTP site. The upgrade is triggered by either a power cycle or option module reset. After the upgrade is performed, the upgrade file is deleted from the meter’s internal SFTP site before the option module is reset to run the new firmware. The option module firmware will not upgrade if more than one upgrade file is in the folder. The upgrade file must be the correct file type and match the type of module being upgraded.

All option modules do not perform their regular functions during firmware upgrade. If more than one option module is being upgraded, the firmware on the option module closest to the meter is done first, then the next closest, proceeding to the furthest module from the meter base requiring upgrading. A single option module firmware upgrade should not take more than five minutes.

The option module upgrade results are stored in your meter’s event log. Detailed information about the option module, such as serial number and firmware version is provided in the Factory module. Information about the option module type and details of the option module’s state is provided in the Diagnostics module.

See the ION Reference, available from www.schneider-electric.com, for more information about the Factory and Diagnostic modules.

Accumulated energy values and upgrades

The firmware upgrade process clears accumulated energy values in the meter.

If you want to retain these values across a firmware upgrade, you can use the Register Edit feature in ION Setup to manually restore pre-upgrade values back to your meter.
