5 Confidential Property of Schneider Electric 1st Test – Shutdown Historian Server >When WWHistorian server is offline (shutdown) Ampla recognizes error and does not capture the data. >Connecting the WWHistorian server again, Ampla reads the updated status “good” of HDA Server and captures the data properly. But considering data backfilling for the period communication was off, it is done the wrong way: first, the value is kept frozen for the whole period. After some minutes, values are correctly updated (not frozen anymore). But at this point, as the status of the frozen value was “good”, Ampla already read it and considered it to write into its database and also for calculations, and it does not consider the updated values.

6 Confidential Property of Schneider Electric 2nd Test – Broken Network Connection between Client and WWHistorian >Ampla does not identify any error connection in Historian Server, so it captures the last value written in WWHistorian. >When broken connection is restablished, there is no backfilling in Ampla history values. >This happens because OPC HDA Integration reads the status of WWHistorian Server and not the data sources configured in WWHistorian. So if one data source shows problem but WWHistorian keeps working, Ampla doesn't read any status if error.

7 Confidential Property of Schneider Electric 3rd Test – Shutdown Ampla Server >When Ampla server is shutdown and returns later, Ampla reads the data and make fill back with no problems - with proper data. >The backfilling period that Ampla considers is the same as configured in SampleStream at Ampla.config file.

8 Confidential Property of Schneider Electric 4th Test – Broken Connection between Ampla and WWHistorian Server >When we break the network connection between WWHistorian and Ampla, OPC HDA Client shows error and Ampla stops capturing the data. Restoring the network connection, Ampla collects all data from the period connection was broken. >It is important to highlight that, if the period of broken connection is longer than the period defined in Ampla’s SampleStream, Ampla won’t fill back the difference between those periods.
