ION8650 151 Errors

Hello,

Does anyone have additional information on 151 errors.  Specifically, what causes these errors on a meter, and what does a 151 error mean? 

I have a customer who was getting these on a couple meters.  When they started coming into the event log, they said that their load profile log stopped updating.  Sometimes a power cycle would correct the issue for a little while but the errors would come back with the same problem.

Thanks for the information in advance.

The short answer is one or more blocks in the flash can not be read.

UPGFileCantRead

As you said it recovers for a time after a power cycle so this condition would likley be resolved by a firmware upgrade to V405 or V406

If a firmware upgrade does not resolve the issue a Flash block is stuck in the read state and the meters would need to be returned for repair.

Root Cause summary:

The firmware design team working with the flash manufacturer discovered there was a potential that certain aspects of the meter's code might affect the internal memory management of the meter.  Firmware enhancements were incorporated into V405 to prevent the possibility of the flash read write issues from occurring.

Recommendations for the customer:

Should a similar occurrence happen the device can sometimes be corrected by power cycling.

If possible an upgrade to 8650V405 firmware which was enhanced to prevent these errors from occurring is suggested.

For devices that already exhibit the symptoms and do not return to normal operation after a power cycle the new firmware may not directly resolve the issue.

If the device has the new firmware and has been power cycled and continues to show the symptoms it will need to be returned for repair.

Schneider Electric internal corrective actions :

Improvements to the firmware have been identified through collaboration between Schneider Electric and its suppliers.

This new firmware will resume read/write cycles once power has been restored to the meter, will change memory blocks from an unknown state to a known state, and will improve memory reliability to safeguard against data loss.
