IEC61850 Server: data inconsistency in reports when timestamp is from variable for t-attribute
Summary
When t-attribute of a data object is managed manually in the zenon Logic project, a report may have been generated with the previous timestamp of the value change.
Description
When t-attribute of a data object is managed manually in the zenon Logic project, a report may have been generated with the previous timestamp of the value change.
Information
No workaround.
Theoretically, would be possible to write program in logic which in separated cycles, first maps t-attribute from the timestamp of zenon variable, and in next cycle - its status bits and value. Maybe tolerable to do on few variables, but not on many. And there is then still risk of data inconsistency: that updated t-attribute would be sent in the report about data change in other DO, and the relevant value/quality change for this DO - in the next report.
