At the turn of the year (2021), some of our customers have encountered problems with filtering the Alarm Message List (AML) or Chronological Event List (CEL/audit trail) in unsupported zenon versions (outside the product life cycle). We're sorry for any inconvenience and have already fixed the issue for several versions. If your installation seems to be affected, <a href="https://go.copadata.com/aml_cel_filtering" target="_blank">please contact us by following the link</a> (and we will provide you with a solution as quickly as possible).
