Data Recording and Timestamping

To help ensure the validity of the test reports and avoid repetition of the test due to data loss, data must be recorded and timestamped at the connected product level. This will allow producing a valid report even if there was a temporary communication loss between the Edge Control software and the connected products during the test.

Advanced meters such as the PowerLogic ION9000, PM8000, and some PowerLogic PM5000 models (PM53xx and PM55xx) can timestamp and record onboard input data, energy measurements, and connected equipment states. EcoStruxure Power Monitoring Expert or Power Operation can then retrieve the records with their original timestamp.

For other connected products (PowerLogic P5/P3, MasterPacT MTZ, entry-level PowerLogic PM5000 models) measurements are acquired by the connected products and then recorded and timestamped by associated Cyber Sciences SER 3200/2408 or by the ASCO CPMA (Critical Power Management Appliance).

Timestamping Requirements for Backup Generator and ATS/PTS

Due to the accuracy requirements of the Generator Test (EPSS) Report, it is necessary to have all status data recorded with high time precision. Depending on the jurisdiction, this is typically greater than ±100 ms.

When using power meters to monitor generator and ATS/PTS, a custom framework is required to record all required data. This framework is described in detail in the Backup Power module in the EcoStruxure Power Monitoring Expert System Guide.

Advanced power meters (PowerLogic ION9000 and PM8000) support this framework.

Timestamping Requirements for UPS

For UPS test reports, time accuracy is not as critical, but should still be within ±1second.
